Definitions

  • the invention relates to a barefoot shoe with bottom and shaft and with locking means for locking the shoe at the foot of a person wearing the shoe and the use of a shoe as barefoot shoe.
  • barefoot walking strengthens muscles, ligaments and joints, improves motor skills, promotes sense of balance and prevents injury. The spine and the rest of the body will benefit as well. Walking barefoot or walking barefoot strengthens the immune system, especially in cold weather. If foot damage is already present, barefoot walking can often correct and alleviate discomfort better than with orthopedic aids.
  • Barefoot walking is considered to be extremely healthy and desirable in many areas of daily life. Basically, one would therefore refrain from shoes, if there were not the risk of injury from lying around objects, rubbish, broken glass, sharp stones, bottle caps, insects, small animals od. Like.
  • One known such outdoor shoe which may be referred to as a sock rather than a shoe, has a dimpled rubber sole which is followed by a fabric upper.
  • This outdoor shoe proves to be particularly problematic when used in wet conditions, since the rubber sole and the fabric can not release stored moisture as quickly as desired and the foot does not have sufficient support when wet.
  • This well-known outdoor shoe is not able to convey the desired barefoot feeling and thus rather unsuitable as a "barefoot shoe”.
  • swimming shoes are known, which firmly enclose the foot of the wearer with the right size selection. As a result of thin materials such swimming shoes leave a person wearing these shoes feel the ground well and also convey a secure feeling.
  • the disadvantage is that such a swimming shoes wearing person sweats heavily and also swimming shoes when using "on land” are not durable. In the event of moisture, water also accumulates in the swimming shoes and the feet not only stay moist, but literally wet. Also swimming shoes are therefore unsuitable for use as "barefoot shoes”.
  • an outdoor shoe with a sole made of grooved natural rubber and a shaft made of polyamide stretch fabric is known.
  • this outdoor shoe is disadvantageous that the feet quickly sweat and penetrated moisture is not sufficient can escape.
  • the sole of this outdoor shoe does not provide adequate support, especially on slippery surfaces. Overall, therefore, this outdoor shoe is not suitable for use as a "barefoot shoe”.
  • the known long socks in Rasteren- or clamping area with closed chain fabric and in particular in this area are formed without locking devices.
  • the training as a closed chain fabric also applies to the floor area.
  • a known chain fabric socks are provided at all locking devices, so they are located on the upper collar, ie already almost in the knee area of the trained as a long socks warp fabric socks person.
  • a barefoot shoe is to be created, which encloses the feet of a person wearing the barefoot shoe fit and tight fitting and without the risk of injury in a quick change wet, dry, cold, warm, etc. feel. Accordingly, the shoe should be well ventilated and react quickly changing to environmental influences, adapt to the foot like a "second skin", be possible to use even in the cold season and sit firmly on the foot in any weather. Furthermore, the creation of pressure points, blisters, abrasions or the like should be avoided. movements Muscles and tendons in the foot are in no way to be impeded by the barefoot shoe. The foot should be reliably protected against injury and penetration of interfering foreign bodies should be avoided as far as possible.
  • the barefoot shoe should be as durable as possible, despite constant change between heat, cold, wet and dry. Furthermore, it is desirable that the static friction properties (so-called "grip") of the barefoot shoe are sufficient, even on variable substrates.
  • the barefoot shoe should be quick to clean and offer better hygienic properties than other so-called barefoot products.
  • the aim is that the barefoot shoe is lightweight and flexible and can be designed visually appealing.
  • the object underlying the invention is achieved by a barefoot shoe according to the preamble of claim 1 by the feature combination of the characterizing part of claim 1.
  • Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
  • the object is achieved by the use of a shoe with bottom and shaft and with locking means for locking the shoe at the foot of a person wearing the shoe whose bottom has wholly or partially of annular structures existing areas as Barefoot.
  • a barefoot shoe which has a bottom and a shank and locking devices for locking the barefoot shoe on the foot of a person wearing the barefoot shoe, and the bottom completely made of at least partially open ring structures consists or at least partially exclusively of ring structures existing areas, resulting for the person wearing such a shoe, especially when used in the "outdoor” area, effects on the skin, which are comparable to a "real" barefoot or close to this because for the wearer of the shoe, the environmental influences, such as humidity, temperature (heat, cold), surface texture u. Like. Immediately noticeable.
  • the locking devices are at least partially provided in the areas of the shaft which are in the wearing state in the instep or instep area, a firmly seated yet slightly slippery and extendable shoe created.
  • the fact that the locking devices are located in the dorsal region is not detrimental to the barefoot shoe - in contrast to the known long-sock warp-knit socks - because the protection of the back of the foot is of secondary importance in a barefoot shoe.
  • the shoe in the dorsal region in particular have a larger opening in the manner of a ballerina shoe, in which case the locking means are formed so that the edge of the opening is acted upon in the manner of a tightening tension with an elastic clamping force.
  • the locking means may also be formed in the manner of known laces or in the manner of buckles or straps fixed with hook and loop fasteners.
  • the bottom consists only partially of at least partially open ring structures.
  • parts of the floor for example in areas of the arch of the foot, which usually have no direct contact with the ground due to the arch anatomy of the sole of the foot, can be realized by means of other materials.
  • the advantages of the ring structures according to the invention and the advantages of conventional shoe materials can be combined with one another.
  • the locking means may also be provided in the dorsal region.
  • the ring structures are at least partially open in the context of the invention, and in contrast, for example, to vulcanized into a rubber layer ring structures od in the field of labor protection garments as penetration protection for nails. Like. Can be useful.
  • at least partially open ring structures may also include configurations in the context of the invention in which, in addition to the ring structures, further substantially permeable fabrics, such as, for example, coarse mesh fabrics, are provided.
  • the barefoot shoe and the structure of the ring structures are designed such that environmental influences can act directly on the foot of a person wearing the barefoot shoe, ie, that the barefoot shoe and the ring structures are ergonomically designed so that the shoes are preferred by a user additional intermediate socks between the foot of the wearer - although the use of intermediate socks, as explained below, is possible - and can be worn without overshoe ,.
  • this results in the advantage of quasi-direct contact of the sole of the foot with the ground with excellent ventilation and faster drying and removal of particulate foreign matter such as sand and at the same time unimpaired protection against injury.
  • the bottom of the barefoot shoe consists entirely of ring structures, and the areas of the shaft adjoining the floor, in particular the toes in the front shoe area and the heel of the person wearing the shoe in the rear shoe area, are integral with the ring structures are formed of the soil and thus also consist of ring structures.
  • the advantages of the present invention are essentially achieved in that at least a portion of the bottom is formed in the form of ring structures and the entire barefoot shoe is designed such that these ring structure portions form an open and / or permeable parting surface structure between the sole of the foot and the ground, ie that the shoe can be worn comfortably without additional socks or overshoes.
  • the remaining parts of the shoe, ie the remaining parts of the bottom and the shaft - can - depending on the specific requirement profiles - either also consist of ring structures, or be made entirely or partially from other customary in the shoe area materials.
  • ring structures are understood to mean fine-meshed flexible surface elements as permeable rasters, which, when loaded by the weight of a person wearing the barefoot shoe, are rigid (surface-stable) and wrap around one another or central holding elements. Metal and / or plastic.
  • the rings of the ring structures may be round, angular (e.g., 4, 6, 8 corners) or oval in shape.
  • the bottom of the barefoot shoe in contrast to solid soles, can be adapted individually to uneven floors. This results in e.g. good holding properties even with problematic substrate conditions such. reached on roots in moist moss growth. Since the foot adapts to the ground due to the relatively small ground support surface of the individual rings of the ring structures and the relatively high weight of the person wearing the shoe with high specific pressure, for example, in moss vegetation on roots press the rings of the ring structures through to the harder wood , which - even when tilted - slipping is unlikely.
  • a person wearing the shoe immediately feels the properties of the ground, temperature differences and differences in humidity at every step.
  • the foot is still better protected by the ring structures from cuts and cuts than in conventional barefoot shoes.
  • Another advantage is that the barefoot shoe can be easily cleaned, for example by washing under running water. Experiments have shown that the barefoot shoe according to the invention does not lead to sore areas, abrasions or bruises on the foot, since the material is applied, with a precise fit However, no permanent friction or permanent pressure exerted on individual sites.
  • the barefoot shoe according to the invention is permeable to air due to the completely permeable grid structure of the ring structures and therefore well ventilated. Due to the flexibility of the ring structures, the area of the barefoot shoe that comes into contact with the substrate adapts perfectly to the respective substructure.
  • the foot can be protected from the cold by thin, arranged inside the barefoot shoe socks, for example, from chloropenic rubber or other suitable, for example, from orthopedic and rehabilitation technology known materials, if necessary.
  • a suitable material is the lining designed for the care of diabetic patients with the product name Diatex of Erkodent Erich Kopp GmbH (DE).
  • an additional sock for example, made of chloroprene rubber or other suitable materials to pull the outside of the barefoot shoe. This may be useful in situations where the adhesion of the ring structures to certain, especially artificially created, soils, e.g. polished granite, to be improved without losing the additional massage effect.
  • the barefoot shoes according to the invention also have good slip resistance properties, in particular on grown soils, since rings of the ring structures are easily set up on each ground contact and thus the comparatively small contact area remaining with the substrate leads to a high, surface-pressure-preventing surface pressure.
  • the design of the rings of the ring structures can be chosen so that, for example, thorny brambles or stinging nettles have no chance to touch the foot of the person wearing the barefoot shoe.
  • dirt particles can basically get into the barefoot shoe, but they are "sifted" through the fabric interstices of the ring structures during the entry, so to speak, and pushed out again by the back pressure of the foot. Due to the small remaining openings between the rings of the ring structures only particles with correspondingly small dimensions come to the skin of the foot. However, these particles are not annoying and only become visible when the shoe is pulled out.
  • the ring structures used in the barefoot shoe according to the invention are durable and easily tolerate changes between hot and cold, dry and wet od. Like. After wet contact the foot is dry again after a few steps. When passing through a puddle of water, the foot of a person wearing the barefoot shoe is pleasantly cooled and is soon dry again. Due to the open structure of the ring structures and thus their continuity, the environmental influences desired in barefoot running thus act directly on the foot of the person wearing the barefoot shoe, as is otherwise the case only with true barefoot walking or walking.
  • the barefoot shoe according to the invention is flexible due to its ring structures and od for storage, transport od. Like.
  • the barefoot shoe can be brought into virtually any desired shape and occupies much less space than conventional shoes.
  • Suitable materials may be selected from the group of metals, metal alloys, (optionally modified) plastics, fibers or composites. Concrete examples of suitable materials are steel or steel alloys, aluminum or aluminum alloys, titanium / stainless steel or corresponding alloys, silver / gold, Brass or brass alloys, copper or copper alloys (including bronze), hard plastics, fiberglass, carbon fiber or aramids.
  • the rings can be welded or soldered. As far as the rings are made of plastic, they can be fused or glued.
  • the number of rings suspended in each other depends on the particular application and is variable.
  • the ring structure has a plurality of interconnected raster elements, wherein each raster element preferably has four rings each, which are mounted in a common connecting ring.
  • the individual grid elements are connected by the fact that the mentioned four or more rings are each mounted in different, as connecting rings or otherwise designed as the central holding elements further correspondingly formed grid elements.
  • Ring structures within the meaning of the present invention also include so-called metal ring braids or flexible structures referred to as so-called “flexible shed braids” in which a multiplicity of elements designated as “shed” or “capsules” are connected to one another via hinged rings.
  • the dandruff or capsules each have closed flat sides and hinged rings in edge regions of the dandruff or capsules.
  • four rings are each hooked into opposite edge regions and together with the respective scale or capsule form a grid element which is in communication with correspondingly formed further grid elements in that each of the four rings mentioned is in edge regions is hung by four more scales or capsules.
  • the dandruff meshes have through openings through which the environmental influences desired in barefoot walking can reach the foot of a person wearing the barefoot shoe.
  • capsules or scales with structures provided on the bottom side can or can be used as the central holding element or as the central holding elements.
  • the bottom of the barefoot shoe may have areas with fewer rings or areas with additional rings of different orientation. Such measures can influence the "grip" behavior of the barefoot shoe.
  • Ring structures made of metal have the advantage of being particularly resistant to ring structures made of other materials.
  • Metal ring structures are particularly suitable for use in areas of high mechanical stress (e.g., changing terrains, hard soils, steep slopes, or the like). Metal ring structures protect against injury.
  • Plastic ring structures have the advantage of being lighter than metal ring structures and more flexible. Ring structures made of plastic are preferably used when it comes to applications with lower mechanical stress (meadows, beaches, soft ground, low risk of injury od. Like.). Barefoot shoes with ring structures made of plastic have a high wearing comfort.
  • the shape and construction of the barefoot shoe according to the invention are variable: between the shape of a so-called footlet or a light ballerina shoe and the shape a high-necked, possibly additionally reinforced outdoor shoe, even in boot shape to over the ankle, many variants are conceivable. It is also possible to make the barefoot shoe in the manner of a simple, stretchable stocking (with toe pockets or without toe pockets). Toe compartments, for example, make sense when the barefoot shoe special requirements (eg climbing requirements) are made.
  • the locking means for locking the shoe to the foot of a person wearing the shoe can be carried out in a conventional manner.
  • Barefoot shoes according to the invention may also have reinforcements and / or additional elements for increasing the grip (so-called “grip improvements"), and also elements for upholstery, insulation or the like.
  • the ring structures may be provided as locking devices, for example, spring-loaded locking hooks, by means of which a stepless lock in correspondingly attached eyelets and the ring fabric itself can be done.

  • softer, flowable surfaces, eg in the sand on the other hand, larger parts of the sole of the foot tend to come into contact with the ground, so that the specific barefoot feeling is intensified here.
  • Such a shoe thus offers a kind of automatic adaptation to the respective ground.

Description

Die Erfindung betrifft einen Barfußschuh mit Boden und Schaft sowie mit Arretiereinrichtungen zum Arretieren des Schuhs am Fuß einer den Schuh tragenden Person sowie die Verwendung eines Schuhs als Barfußschuh.The invention relates to a barefoot shoe with bottom and shaft and with locking means for locking the shoe at the foot of a person wearing the shoe and the use of a shoe as barefoot shoe.

Viele Zivilisationskrankheiten sind auf unsachgemäßen Umgang mit den Füßen und insbesondere auf das Tragen ungeeigneter Schuhe zurückzuführen. Allgemein bekannt ist, dass Barfußgehen bzw. Barfußlaufen Muskeln, Bänder und Gelenke kräftigt, die motorischen Fähigkeiten verbessert, den Gleichgewichtssinn fördert und Verletzungen vorbeugt. Auch die Wirbelsäule und der gesamte restliche Körper profitieren davon. Barfußgehen bzw. Barfußlaufen stärkt die Immunabwehr, insbesondere bei kaltem Wetter. Wenn bereits Fußschäden vorliegen, können durch Barfußlaufen Beschwerden vielfach besser als durch orthopädische Hilfsmittel korrigiert bzw. gelindert werden.Many diseases of civilization are due to improper handling of the feet and in particular to the wearing of unsuitable shoes. It is well known that barefoot walking strengthens muscles, ligaments and joints, improves motor skills, promotes sense of balance and prevents injury. The spine and the rest of the body will benefit as well. Walking barefoot or walking barefoot strengthens the immune system, especially in cold weather. If foot damage is already present, barefoot walking can often correct and alleviate discomfort better than with orthopedic aids.

Barfußlaufen wird als äußerst gesund und in vielen Bereichen des täglichen Lebens als möglich und erstrebenswert angesehen. Grundsätzlich würde man auf Schuhe daher verzichten, wäre da nicht die Verletzungsgefahr durch herumliegende Gegenstände, Unrat, Scherben, spitze Steine, Kronkorken, Insekten, Kleintiere od. dgl.Barefoot walking is considered to be extremely healthy and desirable in many areas of daily life. Basically, one would therefore refrain from shoes, if there were not the risk of injury from lying around objects, rubbish, broken glass, sharp stones, bottle caps, insects, small animals od. Like.

Vor diesem Hintergrund sind bereits sog. "Outdoorschuhe" vorgeschlagen worden, die der solche Schuhe tragenden Person die Vorteile des Barfußgehens bzw. -laufens bei gleichzeitigem Schutz vor Verletzungsgefahr vermitteln sollen.Against this background, so-called "outdoor shoes" have already been proposed which are intended to convey to the person wearing such shoes the advantages of walking or running barefoot while at the same time protecting against the risk of injury.

Ein bekannter derartiger Outdoorschuh, der eher als ein Strumpf als ein Schuh bezeichnet werden kann, weist eine genoppte Gummisohle auf, an die sich ein aus Textilgewebe bestehender Schaft anschließt. Dieser Outdoorschuh erweist sich insbesondere bei einem Einsatz bei Nässe als problematisch, da die Gummisohle und das Textilgewebe gespeicherte Feuchtigkeit nicht so schnell wie gewünscht abgeben kann und der Fuß bei Nässe keinen ausreichenden Halt hat. Dieser bekannte Outdoorschuh ist nicht in der Lage, das gewünschte Barfußgefühl zu vermitteln und somit als "Barfußschuh" eher ungeeignet.One known such outdoor shoe, which may be referred to as a sock rather than a shoe, has a dimpled rubber sole which is followed by a fabric upper. This outdoor shoe proves to be particularly problematic when used in wet conditions, since the rubber sole and the fabric can not release stored moisture as quickly as desired and the foot does not have sufficient support when wet. This well-known outdoor shoe is not able to convey the desired barefoot feeling and thus rather unsuitable as a "barefoot shoe".

Weiterhin ist ein nach Art einer Socke ausgebildeter Outdoorschuh bekannt, bei dem der Boden und der Schaft Strickgut aus einem Gemisch von Textilien und Kunststoff aufweist, an dessen Bodenunterseite eine dort eingeschweißte, aus Polyester bestehende Noppensohle angeordnet ist. Für einzelne Zehen sind in dem Strickgut sog. Zehenfächer vorgesehen. Auch dieser Outdoorschuh vermittelt der ihn tragenden Person kein echtes Barfußgefühl und ist ebenfalls problematisch bei Nässe.Furthermore, a trained in the manner of a sock outdoor shoe is known in which the bottom and the shaft knitted fabric made of a mixture of textiles and plastic, at the bottom bottom there is a welded there, existing polyester nub base is arranged. For individual toes, so-called toe compartments are provided in the knitted fabric. Also, this outdoor shoe gives the person wearing it no real barefoot feeling and is also problematic in the wet.

Bei Versuchen, zum Laufen auf Booten und in Gewässern konzipierte Outdoorschuhe mit Löchern in der Sohle, durch die eingedrungenes Wasser entweichen kann, für den hier angestrebten Zweck einzusetzen, stellte sich heraus, dass die Füße einer diese Schuhe tragenden Person nach aufgetretener Nässe nass bleiben. Auch dieser Outdoorschuh ist somit als "Barfußschuh" ungeeignet.In attempts to use outdoor shoes designed for running on boats and in the water, with holes in the sole through which water can escape, for the purpose intended here, it has been found that the feet of a person wearing these shoes remain wet after wetness has occurred. This outdoor shoe is therefore unsuitable as a "barefoot shoe".

Weiterhin sind sog. Schwimmschuhe bekannt, welche den Fuß des Trägers bei richtiger Größenauswahl fest umschließen. Infolge dünner Materialien lassen derartige Schwimmschuhe eine diese Schuhe tragende Person den Untergrund gut spüren und vermitteln zudem ein sicheres Gefühl. Nachteilig ist aber, dass eine derartige Schwimmschuhe tragende Person stark schwitzt und außerdem Schwimmschuhe bei Benutzung "auf Land" nicht lange haltbar sind. Bei auftretender Feuchtigkeit staut sich zudem Wasser in den Schwimmschuhen und die Füße bleiben nicht nur feucht, sondern regelrecht nass. Auch Schwimmschuhe sind daher für einen Einsatz als "Barfußschuhe" ungeeignet.Furthermore, so-called. Swimming shoes are known, which firmly enclose the foot of the wearer with the right size selection. As a result of thin materials such swimming shoes leave a person wearing these shoes feel the ground well and also convey a secure feeling. The disadvantage, however, is that such a swimming shoes wearing person sweats heavily and also swimming shoes when using "on land" are not durable. In the event of moisture, water also accumulates in the swimming shoes and the feet not only stay moist, but literally wet. Also swimming shoes are therefore unsuitable for use as "barefoot shoes".

Weiterhin ist ein Outdoor-Schuh mit einer aus gerilltem Natur-Kautschuk bestehenden Sohle und einem aus Polyamid-Stretch-Gewebe bestehenden Schaft bekannt. Bei einem Einsatz dieses Outdoor-Schuhs als "Barfußschuh" ist nachteilig, dass die Füße schnell schwitzen und eingedrungene Feuchtigkeit nicht ausreichend entweichen kann. Auch bietet die Sohle dieses Outdoorschuhs insbesondere auf glitschigem Untergrund keinen ausreichenden Halt. Insgesamt ist daher auch dieser Outdoorschuh für einen Einsatz als "Barfußschuh" nicht geeignet.Furthermore, an outdoor shoe with a sole made of grooved natural rubber and a shaft made of polyamide stretch fabric is known. When using this outdoor shoe as a "barefoot shoe" is disadvantageous that the feet quickly sweat and penetrated moisture is not sufficient can escape. Also, the sole of this outdoor shoe does not provide adequate support, especially on slippery surfaces. Overall, therefore, this outdoor shoe is not suitable for use as a "barefoot shoe".

Aus der US 4 841 577 A sind verschiedene Bekleidungsstücke aus Kettengewebe bekannt, u.a. auch Langsocken aus Kettengewebe. Derartige bekannte Kettengewebesocken dienen typischerweise dem Schutz gegenüber Verletzungen der Füße, insbesondere in rauen Arbeitsumgebungen (z.B. beim Umgang mit Kettensägen), und sind daher nicht dahingehend konzipiert, in der Art eines "Barfußschuhs" ohne weitere Über- und Unterschuhe oder Socken getragen zu werden. Auch lassen diese - bzgl. der Passform nur sehr grob gefertigten und nicht eng anliegenden - Kettengewebesocken keine schnellen Bewegungen- wie bspw. Gehen, Laufen, Klettern über größere Distanzen - zu, da das lose, sehr schwere Material zu stark schwingen würde. Ihre Anwendung ist deshalb auf den reinen Körperschutz während des Arbeitens an einer Stelle verbleibend beschränkt. Da es für die Schutzwirkung bei derartigen Bekleidungsstücken besonders auf den Schutz des Fußrückens ankommt, sind die bekannten Langsocken im Fußrücken- bzw. Spannbereich mit geschlossenem Kettengewebe und insbesondere in diesem Bereich ohne Arretiereinrichtungen ausgebildet. Die Ausbildung als geschlossenes Kettengewebe gilt auch für den Bodenbereich. Soweit bei den aus der US 4 841 577 A bekannten Kettengewebesocken überhaupt Arretiereinrichtungen vorgesehen sind, so befinden sich diese am oberen Bund, d.h. schon nahezu im Kniebereich einer die als Langsocken ausgebildeten Kettengewebesocken tragenden Person.From the US 4,841,577 A are various garments made of chain fabric known, including long socks made of chain fabric. Such known warp socks typically serve to protect against injuries to the feet, particularly in harsh working environments (eg when handling chainsaws), and are therefore not designed to be worn in the manner of a "barefoot shoe" without any other over and under shoes or socks. Also, these allow - with respect to the fit only very coarse and not tight fitting - warp socks no fast movements - such as walking, running, climbing over long distances - to, as the loose, very heavy material would swing too much. Their application is therefore limited to the pure body protection while working in one place remaining. Since it is important for the protective effect of such garments on the protection of the foot, the known long socks in Fußrücken- or clamping area with closed chain fabric and in particular in this area are formed without locking devices. The training as a closed chain fabric also applies to the floor area. As far as the from the US 4,841,577 A known chain fabric socks are provided at all locking devices, so they are located on the upper collar, ie already almost in the knee area of the trained as a long socks warp fabric socks person.

Mit dem Gegenstand der vorliegenden Erfindung soll ein Barfußschuh geschaffen werden, der die Füße einer den Barfußschuh tragenden Person passgenau und eng anliegend umschließt und ohne die Gefahr einer Verletzung in schnellem Wechsel nass, trocken, kalt, warm, usw. spüren lässt. Dementsprechend soll der Schuh gut belüftet sein und schnell wechselnd auf Umwelteinflüsse reagieren, sich dem Fuß wie eine "zweite Haut" anpassen, möglichst auch in der kalten Jahreszeit einsetzbar sein und bei jeder Witterung fest am Fuß sitzen. Weiterhin soll ein Entstehen von Druckstellen, Blasen, Abschürfungen od. dgl. vermieden werden. Bewegungen von Muskeln und Sehnen im Fuß sollen durch den Barfußschuh in keiner Weise behindert werden. Der Fuß soll zuverlässig vor Verletzungen geschützt und ein Eindringen störender Fremdkörper soll möglichst vermieden werden. Weiterhin soll der Barfußschuh trotz ständigen Wechsels zwischen Wärme, Kälte, Nässe und Trockenheit möglichst haltbar sein. Weiterhin wird angestrebt, dass die Haftreibungseigenschaften (sog. "Grip") des Barfußschuhs ausreichend sind, auch auf variablen Untergründen. Der Barfußschuh soll schnell zu reinigen sein und bessere hygienische Eigenschaften bieten als andere sog. Barfußprodukte. Zudem wird angestrebt, dass der Barfußschuh leicht und flexibel ist und optisch ansprechend gestaltet werden kann.With the object of the present invention, a barefoot shoe is to be created, which encloses the feet of a person wearing the barefoot shoe fit and tight fitting and without the risk of injury in a quick change wet, dry, cold, warm, etc. feel. Accordingly, the shoe should be well ventilated and react quickly changing to environmental influences, adapt to the foot like a "second skin", be possible to use even in the cold season and sit firmly on the foot in any weather. Furthermore, the creation of pressure points, blisters, abrasions or the like should be avoided. movements Muscles and tendons in the foot are in no way to be impeded by the barefoot shoe. The foot should be reliably protected against injury and penetration of interfering foreign bodies should be avoided as far as possible. Furthermore, the barefoot shoe should be as durable as possible, despite constant change between heat, cold, wet and dry. Furthermore, it is desirable that the static friction properties (so-called "grip") of the barefoot shoe are sufficient, even on variable substrates. The barefoot shoe should be quick to clean and offer better hygienic properties than other so-called barefoot products. In addition, the aim is that the barefoot shoe is lightweight and flexible and can be designed visually appealing.

Die der Erfindung zugrunde liegende Aufgabe wird für einen Barfußschuh gemäß dem Oberbegriff des Patentanspruches 1 durch die Merkmalskombination des Kennzeichnungsteils des Patentanspruches 1 gelöst. Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen. Ferner wird die Aufgabe durch die Verwendung eines Schuhs mit Boden und Schaft sowie mit Arretiereinrichtungen zum Arretieren des Schuhs am Fuß einer den Schuh tragenden Person, dessen Boden ganz oder teilweise aus Ringstrukturen bestehende Bereiche aufweist, als Barfußschuh gelöst.The object underlying the invention is achieved by a barefoot shoe according to the preamble of claim 1 by the feature combination of the characterizing part of claim 1. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims. Furthermore, the object is achieved by the use of a shoe with bottom and shaft and with locking means for locking the shoe at the foot of a person wearing the shoe whose bottom has wholly or partially of annular structures existing areas as Barefoot.

Durch die die vorliegende Erfindung bereits auch für sich genommen charakterisierende Maßnahme, wonach ein Barfußschuh vorgesehen ist, der einen Boden und einen Schaft sowie Arretiereinrichtungen zum Arretieren des Barfußschuhs am Fuß einer den Barfußschuh tragenden Person aufweist, und dessen Boden vollständig aus wenigstens teilweise offen ausgebildeten Ringstrukturen besteht oder wenigstens teilweise ausschließlich aus Ringstrukturen bestehende Bereiche aufweist, ergeben sich für die einen derartigen Schuh tragende Person, insbesondere bei Benutzung im "Outdoor"-Bereich, Wirkungen auf die Fußhaut, die mit einem "echten" Barfußgehen vergleichbar sind bzw. diesem nahe kommen, da für den Träger des Schuhs die Umwelteinflüsse, wie Feuchtigkeit, Temperatur (Wärme, Kälte), Untergrundbeschaffenheit u. dgl. unmittelbar spürbar sind.By the present invention also taken alone characterizing measure, according to which a barefoot shoe is provided, which has a bottom and a shank and locking devices for locking the barefoot shoe on the foot of a person wearing the barefoot shoe, and the bottom completely made of at least partially open ring structures consists or at least partially exclusively of ring structures existing areas, resulting for the person wearing such a shoe, especially when used in the "outdoor" area, effects on the skin, which are comparable to a "real" barefoot or close to this because for the wearer of the shoe, the environmental influences, such as humidity, temperature (heat, cold), surface texture u. Like. Immediately noticeable.

Dadurch, dass bei einem Barfußschuh mit vollständig aus wenigstens teilweise offen ausgebildeten Ringstrukturen bestehendem Boden im Rahmen der Erfindung die Arretiereinrichtungen wenigstens teilweise in den im Tragezustand im Fußrücken- bzw. Spannbereich befindlichen Bereichen des Schaftes vorgesehen sind, wird ein fest sitzender und dennoch leicht an- und ausziehbarer Schuh geschaffen. Der Umstand, dass die Arretiereinrichtungen sich im Fußrückenbereich befinden, ist für den Barfußschuh - im Gegensatz zu den bekannten, als Langsocken ausgebildeten Kettengewebesocken - nicht nachteilig, da der Schutz des Fußrückens bei einem Barfußschuh von sekundärer Bedeutung ist. Vielmehr ist es zur Erzielung eines optimalen Barfußeffektes besonders zweckmäßig, dass Arretiereinrichtungen im Fußrückenbereich vorgesehen sind, denn dadurch wird ein enges Anliegen der Ringstrukturen im Sohlenbereich ermöglicht, so dass der Schuh unmittelbar auf dem nackten Fuß getragen dort idealerweise als "zweite Haut" empfunden wird. Im Rahmen der Erfindung kann der Schuh im Fußrückenbereich insbesondere eine größere Öffnung in der Art eines Ballerinaschuhs aufweisen, wobei dann die Arretiereinrichtungen so ausgebildet sind, dass der Rand der Öffnung in der Art eines Spannzuges mit einer elastischen Spannkraft beaufschlagt wird. Alternativ können die Arretiereinrichtungen auch in der Art von bekannten Schnürungen oder in der Art von Schnallen oder von mit Klettverschlüssen fixierten Laschen ausgebildet sein.Due to the fact that, in the case of a barefoot shoe with bottom consisting entirely of at least partially open ring structures, the locking devices are at least partially provided in the areas of the shaft which are in the wearing state in the instep or instep area, a firmly seated yet slightly slippery and extendable shoe created. The fact that the locking devices are located in the dorsal region is not detrimental to the barefoot shoe - in contrast to the known long-sock warp-knit socks - because the protection of the back of the foot is of secondary importance in a barefoot shoe. Rather, it is particularly useful to achieve an optimal Barfußeffektes that locking means are provided in the dorsal region, because a tight fit of the ring structures in the sole area is made possible, so that the shoe worn directly on the bare foot there is ideally perceived as a "second skin". In the context of the invention, the shoe in the dorsal region in particular have a larger opening in the manner of a ballerina shoe, in which case the locking means are formed so that the edge of the opening is acted upon in the manner of a tightening tension with an elastic clamping force. Alternatively, the locking means may also be formed in the manner of known laces or in the manner of buckles or straps fixed with hook and loop fasteners.

Alternativ kann im Rahmen der Erfindung - unabhängig von der Positionierung der Arretiereinrichtungen - vorgesehen sein, dass der Boden nur teilweise aus wenigstens teilweise offen ausgebildeten Ringstrukturen besteht. Damit können Teile des Bodens, beispielsweise in Bereichen des Fußgewölbes, die aufgrund der Gewölbeanatomie der Fußsohle üblicherweise keinen direkten Bodenkontakt haben, mittels anderer Materialien realisiert werden. Durch eine derartige "gemischte" Gestaltung des Barfußschuhs im Boden- bzw. "Sohlen"-bereich können die Vorteile der erfindungsgemäßen Ringstrukturen sowie die Vorteile konventioneller Schuhmaterialien miteinander kombiniert werden. Selbstverständlich können auch bei einem derartigen, nur teilweise Ringgewebestrukturen im Bodenbereich aufweisenden Schuh die Arretiereinrichtungen auch im Fußrückenbereich vorgesehen sein. Die Ringstrukturen sind im Rahmen der Erfindung wenigstens teilweise offen ausgebildet, und zwar im Gegensatz beispielsweise zu in eine Gummischicht einvulkanisierten Ringstrukturen, die im Bereich von Arbeitsschutzbekleidungsstücken als Durchdringungsschutz für Nägel od. dgl. sinnvoll sein können. Wenigstens teilweise offen Ringstrukturen können im Rahmen der Erfindung aber auch Ausgestaltungen umfassen, bei denen zusätzlich zu den Ringstrukturen noch weitere im Wesentlichen durchlässige Flächengebilde, wie z.B. grobmaschige Netzgewebe, vorgesehen sind.Alternatively, it can be provided in the context of the invention - regardless of the positioning of the locking devices - that the bottom consists only partially of at least partially open ring structures. Thus, parts of the floor, for example in areas of the arch of the foot, which usually have no direct contact with the ground due to the arch anatomy of the sole of the foot, can be realized by means of other materials. By means of such a "mixed" design of the barefoot shoe in the bottom or "sole" area, the advantages of the ring structures according to the invention and the advantages of conventional shoe materials can be combined with one another. Of course, even with such, only partially annular fabric structures in the bottom region having shoe, the locking means may also be provided in the dorsal region. The ring structures are at least partially open in the context of the invention, and in contrast, for example, to vulcanized into a rubber layer ring structures od in the field of labor protection garments as penetration protection for nails. Like. Can be useful. However, at least partially open ring structures may also include configurations in the context of the invention in which, in addition to the ring structures, further substantially permeable fabrics, such as, for example, coarse mesh fabrics, are provided.

Vorteilhafterweise sind der Barfußschuh und die Struktur der Ringstrukturen dahingehend ausgebildet, dass Umwelteinflüsse unmittelbar auf den Fuß einer den Barfußschuh tragenden Person einwirken können, d.h., dass der Barfußschuh und die Ringstrukturen von der Ergonomie her so konzipiert sind, dass die Schuhe von einem Anwender bevorzugt ohne zusätzliche Zwischensocken zwischen Fuß des Trägers - wenngleich die Anwendung von Zwischensocken, wie weiter unten erläutert, möglich ist - sowie ohne Überschuh getragen werden können,. Zusammen mit der vorstehend erwähnten offenen Ausbildung der Ringstrukturen ergibt sich hierdurch der Vorteil des quasi direkten Kontakts der Fußsohle mit dem Untergrund bei gleichzeitig ausgezeichneter Belüftung und schneller Trocknung und Abführung partikelartiger Fremdkörper wie Sand sowie bei gleichzeitig uneingeschränktem Verletzungsschutz.Advantageously, the barefoot shoe and the structure of the ring structures are designed such that environmental influences can act directly on the foot of a person wearing the barefoot shoe, ie, that the barefoot shoe and the ring structures are ergonomically designed so that the shoes are preferred by a user additional intermediate socks between the foot of the wearer - although the use of intermediate socks, as explained below, is possible - and can be worn without overshoe ,. Together with the above-mentioned open design of the ring structures, this results in the advantage of quasi-direct contact of the sole of the foot with the ground with excellent ventilation and faster drying and removal of particulate foreign matter such as sand and at the same time unimpaired protection against injury.

Besonders zweckmäßig ist es, wenn der Boden des Barfußschuhs vollständig aus Ringstrukturen besteht, und die sich an den Boden anschließenden Bereiche des Schaftes, insbesondere die im Vorderschuhbereich die Zehen und im rückwärtigen Schuhbereich die Ferse der den Schuh tragenden Person umschließenden Bereiche, einstückig mit den Ringstrukturen des Bodens ausgebildet sind und somit ebenfalls aus Ringstrukturen bestehen.It is particularly expedient if the bottom of the barefoot shoe consists entirely of ring structures, and the areas of the shaft adjoining the floor, in particular the toes in the front shoe area and the heel of the person wearing the shoe in the rear shoe area, are integral with the ring structures are formed of the soil and thus also consist of ring structures.

Grundsätzlich werden die Vorteile der vorliegenden Erfindung im Wesentlichen dadurch erreicht, dass wenigstens ein Teilbereich des Bodens im Form von Ringstrukturen ausgebildet und der gesamte Barfußschuh derart konzipiert ist, dass diese Ringstrukturteilbereiche ein offenes und/oder durchlässiges Trennflächen-gebilde zwischen Fußsohle und Boden bilden können, d.h., dass der Schuh bequem ohne zusätzliche Socken bzw. Überschuhe getragen werden kann. Die übrigen Teile des Schuhs, d.h. die übrigen Teile des Bodens und des Schafts - können - je nach den spezifischen Anforderungsprofilen - entweder ebenfalls aus Ringstrukturen bestehen, oder ganz oder teilweise aus anderen, im Schuhbereich üblichen Materialien gefertigt sein.In principle, the advantages of the present invention are essentially achieved in that at least a portion of the bottom is formed in the form of ring structures and the entire barefoot shoe is designed such that these ring structure portions form an open and / or permeable parting surface structure between the sole of the foot and the ground, ie that the shoe can be worn comfortably without additional socks or overshoes. The remaining parts of the shoe, ie the remaining parts of the bottom and the shaft - can - depending on the specific requirement profiles - either also consist of ring structures, or be made entirely or partially from other customary in the shoe area materials.

Unter Ringstrukturen werden im Rahmen der vorliegenden Erfindung feinmaschige flexible Flächenelemente als durchlässige Raster verstanden, die sich bei einer Belastung durch das Gewicht einer den Barfußschuh tragenden Person starr (flächenstabil) verhaltende und einander oder zentrale Halteelemente umschlingende Ringe aus u.a. Metall und/oder Kunststoff aufweisen. Die Ringe der Ringstrukturen können rund, eckig (z.B. 4, 6, 8 Ecken) oder oval ausgebildet sein.In the context of the present invention, ring structures are understood to mean fine-meshed flexible surface elements as permeable rasters, which, when loaded by the weight of a person wearing the barefoot shoe, are rigid (surface-stable) and wrap around one another or central holding elements. Metal and / or plastic. The rings of the ring structures may be round, angular (e.g., 4, 6, 8 corners) or oval in shape.

Vorteilhaft bei dem erfindungsgemäßen Einsatz von Ringstrukturen ist auch, dass sich der Boden des Barfußschuhs im Gegensatz zu festen Sohlen individuell an Bodenunebenheiten anpassen kann. Hierdurch werden z.B. gute Halteeigenschaften auch bei problematischen Untergrundverhältnissen wie z.B. bei feuchtem Moosbewuchs auf Wurzeln erreicht. Da sich der Fuß infolge der verhältnismäßig kleinen Bodenauflagefläche der einzelnen Ringe der Ringstrukturen und des relativ hohen Gewichtes einer den Schuh tragenden Person mit hohem spezifischem Druck an den Untergrund anpasst, pressen sich beispielsweise bei Moosbewuchs auf Wurzeln die Ringe des Ringstrukturen bis auf das härtere Holz durch, wodurch - auch bei Schräglage - ein Wegrutschen wenig wahrscheinlich wird.It is also advantageous in the use of ring structures according to the invention that the bottom of the barefoot shoe, in contrast to solid soles, can be adapted individually to uneven floors. This results in e.g. good holding properties even with problematic substrate conditions such. reached on roots in moist moss growth. Since the foot adapts to the ground due to the relatively small ground support surface of the individual rings of the ring structures and the relatively high weight of the person wearing the shoe with high specific pressure, for example, in moss vegetation on roots press the rings of the ring structures through to the harder wood , which - even when tilted - slipping is unlikely.

Eine den Schuh tragende Person spürt bei jedem Schritt die Eigenschaften des Untergrundes sowie Temperaturunterschiede und Feuchtigkeitsunterschiede unmittelbar. Der Fuß ist durch die Ringstrukturen dennoch vor Stichen und Schnitten besser geschützt als in herkömmlichen Barfußschuhen. Ein weiterer Vorteil besteht darin, dass der Barfußschuh leicht gereinigt werden kann, beispielsweise durch Auswaschen unter fließendem Wasser. Versuche haben gezeigt, dass der erfindungsgemäße Barfußschuh nicht zu wunden Bereichen, Abschürfungen oder Druckstellen am Fuß führt, da das Material zwar anliegt, bei genauer Passform jedoch keine dauerhafte Reibung bzw. permanenten Druck an einzelnen Stellen ausübt.A person wearing the shoe immediately feels the properties of the ground, temperature differences and differences in humidity at every step. The foot is still better protected by the ring structures from cuts and cuts than in conventional barefoot shoes. Another advantage is that the barefoot shoe can be easily cleaned, for example by washing under running water. Experiments have shown that the barefoot shoe according to the invention does not lead to sore areas, abrasions or bruises on the foot, since the material is applied, with a precise fit However, no permanent friction or permanent pressure exerted on individual sites.

Versuche haben weiterhin gezeigt, dass das angestrebte Barfußempfinden bei Tragen des erfindungsgemäßen Barfußschuhs (insbesondere auf Naturböden) einem "echten" Barfußempfinden (Gehen bzw. Laufen ohne Schuhe) sehr nahe kommt.Experiments have further shown that the desired barefoot feeling when wearing the barefoot shoe according to the invention (especially on natural floors) a "real" barefoot feeling (walking or running without shoes) comes very close.

Der erfindungsgemäße Barfußschuh ist infolge der vollkommen durchlässigen Rasterstruktur der Ringstrukturen luftdurchlässig und daher gut belüftet. Durch die Flexibilität der Ringstrukturen passt sich der mit dem Untergrund in Kontakt kommende Bereich des Barfußschuhs perfekt der jeweiligen Untergrundstruktur an.The barefoot shoe according to the invention is permeable to air due to the completely permeable grid structure of the ring structures and therefore well ventilated. Due to the flexibility of the ring structures, the area of the barefoot shoe that comes into contact with the substrate adapts perfectly to the respective substructure.

Insbesondere in der kalten Jahreszeit kann der Fuß bei Bedarf vor Kälte durch dünne, im Inneren des Barfußschuhs angeordnete Socken, beispielsweise aus Chloropen-Kautschuk oder anderen geeigneten, beispielsweise aus der Orthopädie- und Rehatechnik bekannten Materialien, geschützt werden. Ein Beispiel für ein derartiges geeignetes Material stellt der zur Versorgung von Diabetes-Patienten konzipierte Futterstoff mit der Produktbezeichnung Diatex der Erkodent Erich Kopp GmbH (DE) dar.Especially in the cold season, the foot can be protected from the cold by thin, arranged inside the barefoot shoe socks, for example, from chloropenic rubber or other suitable, for example, from orthopedic and rehabilitation technology known materials, if necessary. An example of such a suitable material is the lining designed for the care of diabetic patients with the product name Diatex of Erkodent Erich Kopp GmbH (DE).

Auch ist es in bestimmten Situationen denkbar, eine zusätzliche Socke, beispielsweise aus Chloropen-Kautschuk oder anderen geeigneten Materialien, außen über den Barfußschuh zu ziehen. Dies kann in den Situationen zweckmäßig sein, in denen die Haftung der Ringstrukturen auf bestimmten, insbesondere künstlich erstellten Böden, z.B. poliertem Granit, verbessert werden soll, ohne den zusätzlichen Massageeffekt zu verlieren.It is also conceivable in certain situations, an additional sock, for example, made of chloroprene rubber or other suitable materials to pull the outside of the barefoot shoe. This may be useful in situations where the adhesion of the ring structures to certain, especially artificially created, soils, e.g. polished granite, to be improved without losing the additional massage effect.

Die erfindungsgemäßen Barfußschuhe weisen außerdem gute Rutschfestigkeitseigenschaften insbesondere auf gewachsenen Böden auf, da sich Ringe der Ringstrukturen bei jeder Bodenberührung leicht aufstellen und dadurch der mit dem Untergrund verbleibende vergleichsweise kleine Kontaktbereich zu einer hohen, ein Verrutschen verhindernden Flächenpressung führt.The barefoot shoes according to the invention also have good slip resistance properties, in particular on grown soils, since rings of the ring structures are easily set up on each ground contact and thus the comparatively small contact area remaining with the substrate leads to a high, surface-pressure-preventing surface pressure.

Die Gestaltung der Ringe der Ringstrukturen kann sowohl hinsichtlich der Ringverbindungen als auch der Anzahl der Ringe so gewählt werden, dass beispielsweise dornenreiche Brombeerranken oder Brennnesseln keine Chance haben, den Fuß der den Barfußschuh tragenden Person zu berühren. Schmutzpartikel können zwar grundsätzlich in den Barfußschuh gelangen, jedoch werden diese durch die Gewebezwischenräume der Ringstrukturen während des Eintretens sozusagen "gesiebt" und durch den Gegendruck des Fußes unmittelbar danach wieder herausgedrückt. Bedingt durch die kleinen verbleibenden Öffnungen zwischen den Ringen der Ringstrukturen kommen nur Partikel mit entsprechend kleinen Abmessungen bis an die Haut des Fußes. Diese Partikel sind jedoch nicht störend und werden erst sichtbar, wenn der Schuh ausgezogen wird. Die bei dem erfindungsgemäßen Barfußschuh eingesetzten Ringstrukturen sind haltbar und vertragen problemlos Wechsel zwischen Warm und Kalt, Trocken und Nass od. dgl. Nach Nässekontakt ist der Fuß schon nach wenigen Schritten wieder trocken. Bei Durchlaufen einer Wasserpfütze wird der Fuß einer den Barfußschuh tragenden Person angenehm gekühlt und ist schon bald darauf wieder trocken. Die bei einem Barfußlaufen erwünschten Umwelteinflüsse wirken infolge der offenen Struktur der Ringstrukturen und damit deren Durchgängigkeit so unmittelbar auf den Fuß der den Barfußschuh tragenden Person ein, wie es sonst nur bei echtem Barfußlaufen bzw. -gehen der Fall ist.The design of the rings of the ring structures, both in terms of ring connections and the number of rings can be chosen so that, for example, thorny brambles or stinging nettles have no chance to touch the foot of the person wearing the barefoot shoe. Although dirt particles can basically get into the barefoot shoe, but they are "sifted" through the fabric interstices of the ring structures during the entry, so to speak, and pushed out again by the back pressure of the foot. Due to the small remaining openings between the rings of the ring structures only particles with correspondingly small dimensions come to the skin of the foot. However, these particles are not annoying and only become visible when the shoe is pulled out. The ring structures used in the barefoot shoe according to the invention are durable and easily tolerate changes between hot and cold, dry and wet od. Like. After wet contact the foot is dry again after a few steps. When passing through a puddle of water, the foot of a person wearing the barefoot shoe is pleasantly cooled and is soon dry again. Due to the open structure of the ring structures and thus their continuity, the environmental influences desired in barefoot running thus act directly on the foot of the person wearing the barefoot shoe, as is otherwise the case only with true barefoot walking or walking.

Ein weiterer Vorteil des erfindungsgemäßen Barfußschuhs besteht darin, dass dieser infolge seiner Ringstrukturen flexibel ist und zum Aufbewahren, zum Transport od. dgl. des Barfußschuhs in praktisch jede gewünschte Form gebracht werden kann und dabei weit weniger Raum einnimmt als herkömmliche Schuhe.Another advantage of the barefoot shoe according to the invention is that it is flexible due to its ring structures and od for storage, transport od. Like. The barefoot shoe can be brought into virtually any desired shape and occupies much less space than conventional shoes.

Die Ringstrukturen selbst können einzelne Ringe aufweisen, die ineinander oder in ein jeweils zentrales Halteelement eingehängt sind. Geeignete Materialien können aus der Gruppe der Metalle, der Metalllegierungen, der (ggf. modifizierten) Kunststoffe, der Faserstoffe oder der Verbundstoffe gewählt werden. Konkrete Beispiele für geeignete Materialien sind Stahl bzw. Stahllegierungen, Aluminium bzw. Aluminiumlegierungen, Titan/Edelstahl bzw. entsprechende Legierungen, Silber/Gold, Messing bzw. Messinglegierungen, Kupfer bzw. Kupferlegierungen (einschließlich Bronze), Hartkunststoffe, Fiberglas, Kohlefaser oder Aramide.The ring structures themselves may have individual rings which are suspended in each other or in a respective central holding element. Suitable materials may be selected from the group of metals, metal alloys, (optionally modified) plastics, fibers or composites. Concrete examples of suitable materials are steel or steel alloys, aluminum or aluminum alloys, titanium / stainless steel or corresponding alloys, silver / gold, Brass or brass alloys, copper or copper alloys (including bronze), hard plastics, fiberglass, carbon fiber or aramids.

Soweit es sich um Metallringe handelt, können die Ringe verschweißt oder verlötet sein. Soweit die Ringe aus Kunststoff bestehen, können diese verschmolzen oder verklebt sein. Die Anzahl der Ringe, die ineinander eingehängt sind, hängt von der jeweiligen Anwendung ab und ist variabel. Vorzugsweise weist die Ringstruktur eine Vielzahl von miteinander in Verbindung stehenden Rasterelementen auf, wobei jedes Rasterelement vorzugsweise jeweils vier Ringe aufweist, die in einen gemeinsamen Verbindungsring eingehängt sind. Die einzelnen Rasterelemente stehen dadurch miteinander in Verbindung, dass die erwähnten vier oder mehr Ringe jeweils in unterschiedliche, als Verbindungsringe oder als anderweitig ausgebildete zentrale Halteelemente weiterer entsprechend ausgebildeter Rasterelemente eingehängt sind.As far as metal rings are concerned, the rings can be welded or soldered. As far as the rings are made of plastic, they can be fused or glued. The number of rings suspended in each other depends on the particular application and is variable. Preferably, the ring structure has a plurality of interconnected raster elements, wherein each raster element preferably has four rings each, which are mounted in a common connecting ring. The individual grid elements are connected by the fact that the mentioned four or more rings are each mounted in different, as connecting rings or otherwise designed as the central holding elements further correspondingly formed grid elements.

Unter Ringstrukturen im Sinne der vorliegenden Erfindung sind auch sog. Metallringgeflechte oder auch als sog. "flexible Schuppengeflechte" bezeichnete flexible Gebilde zu verstehen, bei denen eine Vielzahl von als "Schuppen" oder "Kapseln" bezeichneter Elemente über eingehängte Ringe untereinander verbunden sind. Die Schuppen oder Kapseln weisen jeweils geschlossen ausgebildete Flachseiten und in Kantenbereiche der Schuppen oder Kapseln eingehängte Ringe auf. Bei beispielsweise mit achteckig begrenzten Flachseiten ausgebildeten Schuppen oder Kapseln sind vier Ringe jeweils in gegenüberliegende Kantenbereiche eingehängt und bilden gemeinsam mit der betreffenden Schuppe bzw. Kapsel ein Rasterelement, welches mit entsprechend ausgebildeten weiteren Rasterelementen dadurch in Verbindung steht, dass jeder der erwähnten vier Ringe in Kantenbereiche von vier weiteren Schuppen bzw. Kapseln eingehängt ist. Zwischen den einzelnen Schuppen bzw. Kapseln weisen die Schuppengeflechte durchgehende Öffnungen auf, durch die die bei Barfußlaufen erwünschten Umwelteinflüsse an den Fuß einer den Barfußschuh tragenden Person gelangen können.Ring structures within the meaning of the present invention also include so-called metal ring braids or flexible structures referred to as so-called "flexible shed braids" in which a multiplicity of elements designated as "shed" or "capsules" are connected to one another via hinged rings. The dandruff or capsules each have closed flat sides and hinged rings in edge regions of the dandruff or capsules. In sheds or capsules designed, for example, with octagonal limited flat sides, four rings are each hooked into opposite edge regions and together with the respective scale or capsule form a grid element which is in communication with correspondingly formed further grid elements in that each of the four rings mentioned is in edge regions is hung by four more scales or capsules. Between the individual scales or capsules, the dandruff meshes have through openings through which the environmental influences desired in barefoot walking can reach the foot of a person wearing the barefoot shoe.

Bei einem Einsatz einer Ringstruktur am Boden kann bzw. können als zentrales Halteelement bzw. als zentrale Halteelemente Kapseln oder Schuppen mit bodenseitig vorgesehenen Strukturen (sog. "Griphilfen") Verwendung finden.When a ring structure is used on the floor, capsules or scales with structures provided on the bottom side (or gripping aids) can or can be used as the central holding element or as the central holding elements.

Der Boden des Barfußschuhs kann -je nach Ausführung - Bereiche mit weniger Ringen oder Bereiche mit zusätzlichen Ringen unterschiedlicher Ausrichtung aufweisen. Durch derartige Maßnahmen kann das "Grip"-Verhalten des Barfußschuhs beeinflusst werden.The bottom of the barefoot shoe, depending on the design, may have areas with fewer rings or areas with additional rings of different orientation. Such measures can influence the "grip" behavior of the barefoot shoe.

Ringstrukturen aus Metall haben den Vorteil, besonders widerstandsfähig zu sein als Ringstrukturen aus anderen Materialien. Aus Metall bestehende Ringstrukturen sind für einen Einsatz in Gebieten mit hohen mechanischen Beanspruchungen (z.B. wechselndes Gelände, harte Böden, steile Anstiege od. dgl.) besonders geeignet. Metall-Ringstrukturen schützen besonders gut vor Verletzungen.Ring structures made of metal have the advantage of being particularly resistant to ring structures made of other materials. Metal ring structures are particularly suitable for use in areas of high mechanical stress (e.g., changing terrains, hard soils, steep slopes, or the like). Metal ring structures protect against injury.

Ringstrukturen aus Kunststoff haben den Vorteil, leichter als Ringstrukturen aus Metall und außerdem flexibler zu sein. Ringstrukturen aus Kunststoff werden bevorzugt eingesetzt, wenn es sich um Anwendungen mit geringerer mechanischer Beanspruchung handelt (Wiesen, Strände, weiche Böden, geringes Verletzungsrisiko od. dgl.). Barfußschuhe mit Ringstrukturen aus Kunststoff weisen einen hohen Tragekomfort auf.Plastic ring structures have the advantage of being lighter than metal ring structures and more flexible. Ring structures made of plastic are preferably used when it comes to applications with lower mechanical stress (meadows, beaches, soft ground, low risk of injury od. Like.). Barefoot shoes with ring structures made of plastic have a high wearing comfort.

Bevorzugte Abmessungen der Ringe der erfindungsgemäß vorgesehenen Ringstrukturen können beispielsweise sein:

  • Ring-Außendurchmesser: zwischen 2 mm und 7 mm; Drahtdurchmesser des Ringes: zwischen 0,4 mm und 1,25 mm. Bei einem besonders bevorzugten Ausführungsbeispiel werden Ringstrukturen aus rostfreiem Edelstahl eingesetzt. Die Ringe weisen Ring-Außendurchmesser von 4,0 mm und Ring-Innendurchmesser von 2,9 mm auf. Der Drahtdurchmesser beträgt 0,55 mm.
Preferred dimensions of the rings of the ring structures provided according to the invention can be, for example:
  • Ring outside diameter: between 2 mm and 7 mm; Wire diameter of the ring: between 0.4 mm and 1.25 mm. In a particularly preferred embodiment ring structures made of stainless steel are used. The rings have a ring outside diameter of 4.0mm and a ring inside diameter of 2.9mm. The wire diameter is 0.55 mm.

Form und Machart des erfindungsgemäßen Barfußschuhs sind variabel: Zwischen der Form eines sog. Füßlings oder eines leichten Ballerina-Schuhs und der Form eines hochgeschlossenen, ggf. zusätzlich verstärktem Outdoorschuhs, auch in Stiefelform bis über den Knöchel, sind viele Varianten vorstellbar. Es ist auch möglich, den Barfußschuh nach Art eines einfachen, spannbaren Strumpfes (mit Zehenfächern oder ohne Zehenfächer) zu gestalten. Zehenfächer sind beispielsweise dann sinnvoll, wenn an den Barfußschuh besondere Anforderungen (beispielsweise Kletteranforderungen) gestellt werden.The shape and construction of the barefoot shoe according to the invention are variable: between the shape of a so-called footlet or a light ballerina shoe and the shape a high-necked, possibly additionally reinforced outdoor shoe, even in boot shape to over the ankle, many variants are conceivable. It is also possible to make the barefoot shoe in the manner of a simple, stretchable stocking (with toe pockets or without toe pockets). Toe compartments, for example, make sense when the barefoot shoe special requirements (eg climbing requirements) are made.

Die Arretiereinrichtungen zum Arretieren des Schuhs am Fuß einer den Schuh tragenden Person können in herkömmlicher Art und Weise ausgeführt werden. Erfindungsgemäße Barfußschuhe können auch Verstärkungen und/oder Zusatzelemente zur Erhöhung der Griffigkeit (sog. "Grip-Verbesserungen"), und auch Elemente zur Polsterung, Dämmung od. dgl. aufweisen.The locking means for locking the shoe to the foot of a person wearing the shoe can be carried out in a conventional manner. Barefoot shoes according to the invention may also have reinforcements and / or additional elements for increasing the grip (so-called "grip improvements"), and also elements for upholstery, insulation or the like.

Zur Arretierung der Ringstrukturen können als Arretiereinrichtungen beispielsweise federvorgespannte Verschlusshaken vorgesehen sein, mittels derer eine stufenlose Arretierung in entsprechend angebrachten Ösen und dem Ringgewebe selbst erfolgen kann. Es ist jedoch für die Arretiereinrichtungen auch eine Kombination aus bei herkömmlichen Schuhen bekannten Materialien möglich, wie beispielsweise Leder, Textilmaterialien, Kunststoffe, Bänder, Schnürsenkel, Riemen, Reißverschlüsse, Stretchmaterialien, Klettverschlüssen, partiellen oder vollständigen Metall-, Kunststoff- bzw. Gummi- und Kautschukverstärkungen an Sohlen, Seitenbereichen, Fersen, Spitzen, Spann usw. oder auch Schnallen und/oder Druckknöpfe.To lock the ring structures may be provided as locking devices, for example, spring-loaded locking hooks, by means of which a stepless lock in correspondingly attached eyelets and the ring fabric itself can be done. However, it is possible for the locking a combination of conventional shoes known materials such as leather, textile materials, plastics, tapes, laces, straps, zippers, stretch materials, Velcro, partial or complete metal, plastic or rubber and Rubber reinforcements on soles, side panels, heels, toes, instep, etc., or buckles and / or snaps.

In zweckmäßiger Ausgestaltung kann vorgesehen sein, dass bei dem Barfußschuh der Boden im Bereich der Großzehenballen und/oder im Fersenbereich und/oder im Zehenbereich ganz oder teilweise aus einem geschlossenen Material ausgebildet ist, wohingegen in wenigstens einem angrenzenden Bodenbereich Ringstrukturen vorgesehen sind. Dadurch, dass im Bereich der anatomisch bedingt primär lasttragenden Bereiche der Sohle wenigstens teilweise konventionelle Sohlen verwendet werden, lässt sich erreichen, dass auf harten und glatten Untergründen, wie z.B. Asphalt oder Marmor, im Wesentlichen die konventionellen Sohlenbereiche wirken, die beispielsweise auch Stoßdämpfungseigenschaften aufweisen können. Auf weicheren, fließfähigen Untergründen, z.B. im Sand, treten dagegen tendenziell größere Teile der Fußsohle mit dem Untergrund in Kontakt, so dass sich das spezifische Barfußgefühl hier verstärkt einstellt. Ein derartiger Schuh bietet somit eine Art automatischer Anpassung an den jeweiligen Untergrund.In an expedient embodiment, it can be provided that in the barefoot shoe, the floor in the region of the big toe bales and / or in the heel area and / or in the toe area is completely or partially formed from a closed material, whereas ring structures are provided in at least one adjoining floor area. Because at least partially conventional soles are used in the region of the anatomically primarily load-bearing regions of the sole, it is possible to act on hard and smooth substrates, such as asphalt or marble, essentially the conventional sole regions, for example also shock absorption properties can have. On softer, flowable surfaces, eg in the sand, on the other hand, larger parts of the sole of the foot tend to come into contact with the ground, so that the specific barefoot feeling is intensified here. Such a shoe thus offers a kind of automatic adaptation to the respective ground.

Alternativ kann die Materialverteilung auch umgekehrt ausgestaltet werden, um beispielsweise für weichere Böden für die Ballenbereiche Ringstrukturen bereitzustellen und gleichzeitig mittels durchgehender Sohlenteile den empfindlicheren Mittelfußbereich zu schützen.Alternatively, the material distribution can also be configured in reverse order, for example, to provide ring structures for softer soils for the ball areas and at the same time to protect the more sensitive metatarsal area by means of continuous sole parts.

Ein in den Figuren 1a bis 1d dargestellter in Form eines Ballerina-Schuhs ausgebildeter Barfußschuh gemäß der vorliegenden Erfindung weist einen Boden 1 sowie einen Schaft 2 auf. Der obere Rand des Schaftes 2 (wie ersichtlich im Fußrücken- oder Spannbereich) weist eine Arretiereinrichtung 3 auf, die ein in einen umlaufenden Kanal 4 eingeführtes Schließband 5 aufweist, welches an den Enden 6 und 7 mit knopfartigen Verstärkungen versehen ist, die ein Herausrutschen des Schließbandes verhindern. Im Fersenbereich befindet sich eine verstellbare und feststellbare Verschlusseinrichtung 8.One in the FIGS. 1a to 1d illustrated in the form of a ballerina shoe barefoot shoe according to the present invention has a bottom 1 and a shaft 2. The upper edge of the shaft 2 (as seen in Fußrücken- or clamping area) has a locking device 3, which in a circumferential Channel 4 introduced closing strap 5, which is provided at the ends 6 and 7 with button-like reinforcements, which prevent slipping out of the closing strap. In the heel area is an adjustable and lockable closure device 8.

Sowohl der Boden 1 als auch der Schaft 2 bestehen vollständig aus Ringstrukturen. Die Ringstrukturen des Bodens 1 und des Schaftes 2 sind ineinander übergehend ausgebildet.Both the bottom 1 and the shaft 2 are made entirely of ring structures. The ring structures of the bottom 1 and the shaft 2 are formed merge into one another.

Eine den Schuh gemäß Fig. 1a bis 1d an vorzugsweise nackten Füßen tragende Person steht mit den Fußsohlen und den an die Fußsohlen angrenzenden Fußbereichen mit dem Untergrund ausschließlich über die Ringstrukturen in Verbindung. Wie bereits erwähnt, hat dies für die den Schuh tragende Person den Effekt eines Barfußlaufens, jedoch ohne die bei "echtem" Barfußlaufen damit verbundenen Gefahren. Zudem erfährt der Fuß durch Wirkung der Ringstrukturen eine Fußreflexzonenmassage, die belebt, entspannt und wichtige körpereigene Selbstheilungsprozesse aktiviert.A shoe according to Fig. 1a to 1d Person preferably carrying bare feet is connected with the soles of the feet and the foot areas adjacent to the soles of the feet with the substrate exclusively via the ring structures. As already mentioned, this has the effect of walking barefoot for the person wearing the shoe, but without the dangers associated with "real" barefoot running. In addition, through the action of the ring structures, the foot undergoes a foot reflexology massage, which invigorates, relaxes and activates important body-own self-healing processes.

Fig. 2 zeigt eine weitere Ausführungsform, bei der der (nicht dargestellte) Fuß einer den Schuh tragenden Person durch einen strumpfartig ausgebildeten Barfußschuh 9 umschließbar ist. Der Boden des Schuhs 9 besteht auch hier aus Ringstruktur, an die sich ohne Übergang einen Teil des Schaftes umschließende Ringstrukturbereiche 10 anschließen. Der Fuß der den Schuh tragenden Person ist auch in dem sich nach oben anschließenden Bereich von Ringstruktur 11 umschlossen, welche durch Bänder 12 und 13 arretiert wird. Die Oberkante des Ringstrukturbereiches 10 ist - wie ersichtlich im Fußrücken- oder Spannbereich - durch ein Band 14 arretiert. Fig. 2 shows a further embodiment in which the (not shown) foot of a person wearing the shoe by a stocking barefoot shoe 9 is umschließbar. The bottom of the shoe 9 also consists here of ring structure to which adjoin without transition a part of the shaft enclosing ring structure regions 10. The foot of the person wearing the shoe is also enclosed in the upwardly adjoining region of ring structure 11, which is locked by straps 12 and 13. The upper edge of the ring structure region 10 is - as can be seen in the Fußrücken- or clamping area - locked by a belt 14.

Fig. 3 zeigt einen Ausschnitt einer erfindungsgemäß einsetzbaren Ringstruktur 15. Die Ringstruktur 15 besteht aus einzelnen ineinander eingehängten Ringen, wobei jeweils vier Ringe 16, 17, 18 und 19 in einen gemeinsamen Verbindungsring 20 eingehängt sind. Der Verbindungsring 20 bildet mit den vier Ringen 16 bis 19 ein Rasterelement. Die Ringe 16, 17, 18 und 19 stellen gleichzeitig Verbindungsringe angrenzender Rasterelemente dar, in die jeweils vier Ringe eingehängt sind, usw. Fig. 3 shows a section of an inventively usable ring structure 15. The ring structure 15 consists of individual hinged rings, each four rings 16, 17, 18 and 19 are mounted in a common connecting ring 20. The connecting ring 20 forms with the four rings 16 to 19 a Grid element. The rings 16, 17, 18 and 19 simultaneously represent connecting rings of adjacent grid elements, in each of which four rings are mounted, etc.

Fig. 4 und Fig. 5 zeigen weitere Ausführungsmöglichkeiten. So können beispielsweise parallel angeordnete Verbindungsringe 21 und 22 jeweils gleicher Größe vorgesehen sein, in die jeweils Ringe 23 bis 28 eingehängt sind. 4 and FIG. 5 show more execution options. For example, parallel connection rings 21 and 22 of the same size can be provided, in each of which rings 23 to 28 are suspended.

Gemäß Fig. 5 sind Verbindungsringe 29 und 30 vorgesehen, in die Ringe 31 bis 36 eingehängt sind.According to Fig. 5 are connecting rings 29 and 30 are provided, are suspended in the rings 31 to 36.

Wie weiter unten unter Bezugnahme auf Fig. 14 und Fig. 18 näher erläutert, kann auch vorgesehen sein, dass die Ringstruktur in Teilbereichen zusätzliche Einzelringe aufweist, die jeweils den Überdeckungsbereich von zwei ineinander eingehängten Ringen umschließen und einen gleich großen oder auch kürzeren Umfang als diese Ringe aufweisen.As explained below with reference to Fig. 14 and Fig. 18 explained in more detail, it can also be provided that the ring structure in subregions has additional individual rings, each enclosing the overlap region of two interlinked rings and have an equal or shorter circumference than these rings.

Weiterhin kann, wie weiter unten unter Bezugnahme auf Fig. 15 näher erläutert, vorgesehen sein, dass die (ersten) Ringstrukturen des Bodens und des Schaftes wenigstens in Teilbereichen eine jeweils parallel zu den Ringstrukturen verlaufende zweite Ringstrukturlage aufweisen, und diese zweite Ringstrukturlage mit den (ersten) Ringstrukturen über zusätzliche Einzelringe miteinander in Verbindung steht.Furthermore, as further explained below with reference to Fig. 15 explained in more detail, it can be provided that the (first) ring structures of the bottom and the shaft have at least in partial regions a second ring structure layer running parallel to the ring structures, and this second ring structure layer is in communication with the (first) ring structures via additional individual rings.

Die Querschnitte der Ringe können, wie aus den Fig. 6a bis Fig. 6c ersichtlich, unterschiedlich gestaltet sein.

Fig. 22 shows a schematic representation of a sewing technique for connecting ring structures with other fabrics, such as an outer material. Two such sheets 102, 102 'with sandwiched ring structures 100, 101 are sewn together by stitching through a thread 103 alternately pierced through the ring spaces and the sheets.

Eine Alternative ist in Fig. 23 schematisch angedeutet. Dort ist ein Teil der Ringe 100, 101 in das zu verbindende Flächengebilde 104 eingegossen oder einvulkanisiert.An alternative is in Fig. 23 indicated schematically. There is a part of the rings 100, 101 cast or vulcanized into the sheet 104 to be joined.

In Fig. 24a und 24b sind schematisch erfindungsgemäße Barfußschuhe dargestellt, bei denen ein Zehenbereich 108, ein Sohlengewölbebereich 107, ein Hackenbereich 106 sowie ein Fersenbeinbereich 105 aus Ringstrukturen bestehen; die übrigen Bereiche bestehen aus anderen Materialien (nicht dargestellt). Wie in Fig. 24a in einer Art Explosionsdarstellung gezeigt, können die Ringstrukturen in den besonders beanspruchten Zehen- und Hackenbereichen zusätzlich mit Kappen 106', 108' aus einem geschlossenen Material versehen werden, die den in Laufrichtung besonders exponierten Teilen des Fußes einen erweiterten mechanischen Schutz vor Verletzungen, z.B. für den Fall von Kollisionen mit Steinen etc., gewährleisten. Die Kappen 106', 108' können bezüglich des Ringgewebes außenseitig vorgesehen sein, wie dargestellt, und/oder innenseitig angebracht oder mit dem Ringgewebe durch Einvulkanisation od. dgl. innig verbunden sein.In Figs. 24a and 24b schematically barefoot shoes according to the invention are shown in which a toe area 108, a sole arch region 107, a heel region 106 and a heel bone region 105 consist of ring structures; the remaining areas are made of other materials (not shown). As in Fig. 24a shown in a kind of exploded view, the ring structures in the particularly stressed toe and heel areas can be additionally provided with caps 106 ', 108' of a closed material that the most exposed in the direction of parts of the foot extended mechanical protection against injury, eg for ensure the case of collisions with stones, etc. The caps 106 ', 108' may be provided on the outside with respect to the ring fabric, as shown, and / or attached on the inside or od with the ring fabric by vulcanization. Like. Connected.

Wie aus den Fig. 25a und 25b ersichtlich, können in einer alternativen Ausführungsform die stärker beanspruchten Zehenbereiche 108' und die Hackenbereiche 106' ausschließlich aus nicht durchlässigem, konventionellem Material, und der Sohlengewölbebereich 107 und der Fersenbeinbereich 105 aus Ringgewebe bestehen.Like from the Figs. 25a and 25b As can be seen, in an alternative embodiment, the toe regions 108 'and the heel regions 106', which are more heavily stressed, may consist exclusively of impermeable, conventional material, and the sole arch region 107 and heel bone region 105 may be made of ring fabric.

Die Fig. 25a und 25b stellen mögliche Ausführungsbeispiele eines Barfußschuhs dar, bei dem die Teile der Fußsohle, die anatomisch bedingt die Hauptlast tragen, insbesondere der Großzehenballen sowie der Fersenbereich und ggf. der Zehenbereich, ganz oder teilweise mit einer konventionellen Sohle abgestützt werden, wohingegen in wenigstens einem angrenzenden Sohlenbereich Ringstrukturen vorgesehen sind. Dadurch wird nicht nur erreicht, dass der Fuß gut belüftet und vor Verletzungen geschützt ist. Vielmehr lässt sich hierdurch auch erreichen, dass auf harten und glatten Untergründen, wie z.B. Asphalt, im Wesentlichen die konventionellen Sohlenbereiche zum Einsatz kommen, die beispielsweise auch Stoßdämpfungseigenschaften aufweisen können. Auf weicheren, fließfähigen Untergründen, z.B. auf Sand, treten dagegen tendenziell größere Teile der Fußsohle mit dem Untergrund in Kontakt, so dass sich insbesondere das spezifische Barfußgefühl hier verstärkt einstellt. Ein derartiger Schuh bietet somit eine Art automatischer Anpassung an den jeweiligen Untergrund.The Figs. 25a and 25b represent possible embodiments of a barefoot shoe, in which the parts of the sole of the foot bearing anatomically the main load, in particular the big toe bale as well as the heel area and possibly the toe area, wholly or partially supported by a conventional sole, whereas in at least one adjacent sole region ring structures are provided. This not only ensures that the foot is well ventilated and protected from injury. On the contrary, it is also possible to achieve that, on hard and smooth substrates, such as asphalt, essentially the conventional sole areas are used which, for example, can also have shock-absorbing properties. On softer, flowable surfaces, eg on sand, on the other hand, larger parts of the sole of the foot tend to come into contact with the ground, so that in particular the specific barefoot feeling is intensified here. Such a shoe thus offers a kind of automatic adaptation to the respective ground.

In Fig. 26 ist eine Barfußschuh-Sandale in einer Unteransicht dargestellt, bei der gegen einen mit 110 bezeichneten Fuß sohlenseitig Ringgewebestrukturen 111, 112 lediglich in den Ballen- und Hackenbereichen anliegen, die von konventionellen Materialien 111', 112' umkantet sind. Der Sohlengewölbebereich und der Zehenbereich bleiben bei dieser Ausführungsform frei.In Fig. 26 For example, a barefoot shoe sandal is shown in a bottom view in which, against a foot designated 110, ring fabric structures 111, 112 rest only in the bale and heel regions which are folded over by conventional materials 111 ', 112'. The sole arch area and the toe area remain free in this embodiment.

In den Figuren 27a bis 27c sind verschiedene Ausführungsformen erfindungsgemäßer Barfußschuhe mit durchgehend aus Ringstrukturen bestehenden Sohlenbereichen und unterschiedlichen Obermaterialgestaltungen sowie Arretiereinrichtungen dargestellt.In the FIGS. 27a to 27c Various embodiments of barefoot shoes according to the invention are shown with sole regions consisting of ring structures and different upper material configurations as well as locking devices.

Bei Fig. 27a handelt es sich um einen Schuh mit einer Arretiereinrichtung, die als am oberen Rand des Schuhs umlaufende Kordel ausgebildet ist, die mit einem Kordelstopper 113 festgezogen werden kann.at Fig. 27a it is a shoe with a locking device, which is designed as a circulating at the top of the shoe cord, which can be tightened with a cord stopper 113.

Bei dem in den Figuren 28a-c dargestellten Barfußschuh ist als Untertrageschicht unterhalb des ansonsten ballerinaartig ausgebildeten Ringgewebeschuhs (vgl. die Fig. 1a und 1b) eine den Fuß nur teilweise umschließende Untersocke 115 aus einem Chloropren-Kautschuk (in Deutschland unter dem Markennamen "Neopren®" bekannt) vorgesehen.In the in the Figures 28a-c Barefoot shoe shown is as a sub-base layer below the otherwise ballerina-like ring cloth shoe (see Fig. 1a and 1b ) provided a foot only partially enclosing sock 115 of a chloroprene rubber (known in Germany under the brand name "Neoprene®").

Dieser "Teilsocken" 115 ist in der Darstellung der Figuren 28a-c im Mittelfuß- und Fersenbereich offen ausgebildet. Ein offen ausgebildeter Bereich kann aber alternativ oder zusätzlich auch im Zehenbereich vorgesehen sein. Diese Variante gewährleistet ein ausgezeichnetes Barfußgefühl bei gleichzeitig erhöhtem Tragekomfort. Das Material des Socken gewährleistet u.a., dass im Spannbereich keine Irritationen der Haut oder Druckstellen durch eine dort vorhandene Arretierung auftreten; ferner werden im Schuh vorn die Zehenkuppen, insbesondere die Zehnägel vor dem eventuellen Verhaken mit dem Ringgewebe geschützt.This "partial cam" 115 is in the illustration of Figures 28a-c formed open in the midfoot and heel area. However, an open trained area may alternatively or additionally be provided in the toe area. This variant ensures an excellent barefoot feel with increased wearing comfort. The material of the socks ensures, among other things, that no irritations of the skin or pressure points occur in the clamping area due to the locking provided there; Furthermore, the toe humps, especially the toenails, are protected from possible entanglement with the ring fabric in the front shoe.
