Description

この発明は、氷面や圧雪面などの凍結面上での歩行性と未圧雪の雪面上での歩行性とに優れるとともに、耐久性に優れた靴底を有したシューズに関する。   The present invention relates to a shoe having a shoe sole that is excellent in walking performance on a frozen surface such as an ice surface or a snow pressure surface and in walking performance on a snow surface of uncompressed snow and excellent in durability.

従来、氷面や圧雪面などにおける防滑性と、磨かれた石材などからなる滑りやすい床面での防滑性との両立を図った靴底として、実開昭62−21904号公報にて開示された技術が知られている。この技術は、低硬度の柔らかいゴム中に短繊維をその繊維長方向を一方向に指向させて混入してなる短繊維混入ゴムと、発泡ゴムとを靴底の接地面に交互に配設するようにしたものであり、前記短繊維混入ゴムは短繊維の指向方向が靴底の厚み方向に向くように配設されている。即ち、短繊維混入ゴムは、荷重により低硬度のゴムが圧縮変形すると、これに混入されている短繊維の先端が突出して氷面や圧雪面に突き刺さり、もって防滑性が得られるようになっている。また、発泡ゴムによって、磨かれた石材などからなる滑りやすい床面での防滑性が得られるようになっている。
実開昭62−21904号公報
Conventionally, it has been disclosed in Japanese Utility Model Publication No. 62-21904 as a shoe sole that achieves both slip resistance on an ice surface, a snow pressure surface, etc. and slip resistance on a slippery floor surface made of polished stone. Technologies are known. In this technology, short fiber mixed rubber formed by mixing short fibers in a low hardness soft rubber with the fiber length direction oriented in one direction and foamed rubber are alternately arranged on the ground contact surface of the shoe sole. The short fiber-containing rubber is arranged so that the direction of the short fibers is directed in the thickness direction of the shoe sole. That is, when rubber with a short fiber is compressed and deformed by a load due to a load, the tip of the short fiber mixed in the rubber protrudes and pierces the ice surface or the snow pressure surface, thereby providing anti-slip properties. Yes. In addition, the foam rubber provides anti-slip properties on a slippery floor made of polished stone or the like.
Japanese Utility Model Publication No. 62-21904

しかしながら、上記公報にて開示された靴底構造では、氷面や圧雪面などにおける防滑性と、磨かれた石材などからなる滑りやすい床面での防滑性との両立を図ることはできても、踏み固められていない未圧雪面でのグリップ力を十分に得ることができないという課題があった。即ち、未圧雪面ではこれを踏み締めながら歩行しても、その踏み締められた雪の表面は、氷面や圧雪面程には硬くなることはない。このため、短繊維混入ゴムから短繊維の先端が突出しても、当該先端部は踏み締められた雪面に突き刺さって食い込むことはなく、踏み締めた雪面上を滑ってしまうことになる。しかも、その靴底面は凹凸の少ない平坦な形状となっているので、踏み締めた雪面を凹凸部で捕らえてグリップすることもできない。   However, in the shoe sole structure disclosed in the above publication, it is possible to achieve both the slip resistance on the ice surface and the snow pressure surface and the slip resistance on the slippery floor surface made of polished stone or the like. However, there was a problem that it was not possible to obtain a sufficient grip force on an unpressed snow surface that was not treaded. That is, even if it walks while stepping on an unstressed snow surface, the surface of the snow that has been stepped on does not become as hard as an ice surface or a pressed snow surface. For this reason, even if the tip of the short fiber protrudes from the rubber mixed with the short fiber, the tip does not pierce and bite into the snow surface that has been stepped on and slips on the snow surface that has been stepped on. Moreover, since the bottom of the shoe has a flat shape with little unevenness, the snow surface that has been stepped on cannot be caught and gripped by the uneven portions.

本発明は、上記課題に鑑みてなされたものであって、その目的とするところは、氷面や圧雪面などの凍結面上での歩行時に十分なグリップ力が得られると共に、未圧雪の雪面上での歩行時にも十分なグリップ力が得られて、靴底の滑動を可及的に防止することができ、もって凍結面や雪面での歩行性の可及的な向上が図れるシューズを提供することにある。   The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to obtain a sufficient grip force when walking on a frozen surface such as an ice surface or a compressed snow surface, as well as uncompressed snow. A shoe that provides sufficient gripping force even when walking on the surface and prevents the sole from sliding as much as possible, thus improving the walking ability on frozen and snow surfaces as much as possible. Is to provide.

上記の目的を達成するために、この発明にあっては、合成ゴム中にガラス繊維が混入され、該ガラス繊維はその繊維長方向がソール厚み方向に配向されている領域を有して形成されたアウターソールを具備するシューズにおいて、該領域が、靴長方向に沿って靴幅方向の内足部と中央部と外足部との3つの部位に区分けされて設けられ、該内足部領域と外足部領域とには、該合成ゴムに軟質なものが使用される一方、該中央部領域には、該合成ゴムに硬質なものが使用され、該中央部領域における靴底形状は、複数の凹条及び凸条が靴幅方向に延びて形成され、該内足部領域と該外足部領域とにおける靴底形状は、該中央部領域の凸条よりも幅広で突出面が平坦な凸条が形成されている、ことを特徴とする。   In order to achieve the above object, in the present invention, glass fiber is mixed in synthetic rubber, and the glass fiber is formed having a region in which the fiber length direction is oriented in the sole thickness direction. In the shoe having an outer sole, the region is provided by being divided into three portions of an inner foot portion, a central portion, and an outer foot portion in the shoe width direction along the shoe length direction. For the outer foot region, a soft material is used for the synthetic rubber, while for the central region, a hard material is used for the synthetic rubber, and the sole shape in the central region is A plurality of ridges and ridges are formed extending in the shoe width direction, and the shoe sole shape in the inner foot region and the outer foot region is wider than the ridges in the central region and the protruding surface is flat. It is characterized in that a ridge is formed.

ここで、前記アウターソール下面の前記中央部領域において、土踏まず部よりも靴長方向前方の爪先側に位置した部位では、前記凸条は、爪先側面が傾斜面に形成されて踵側面がほぼ鉛直面に形成される一方、該土踏まず部よりも靴長方向後方の踵側の部位では、該凸条は、踵側面が傾斜面に形成されて爪先側面がほぼ鉛直面に形成されている、構成となすのが望ましい。   Here, in the central region of the lower surface of the outer sole, in the portion located on the toe side ahead of the arch portion in the shoe length direction, the toe side surface is formed as an inclined surface and the heel side surface is substantially vertical. On the other hand, at the heel side portion behind the arch portion, the ridge side is formed as an inclined surface and the toe side surface is formed as a substantially vertical surface. It is desirable that

また、前記アウターソール下面の中央部領域において、土踏まず部よりも靴長方向前方の爪先側の部位では、前記凹条及び前記凸条は、靴幅方向中央部が爪先側に寄った平面視への字状に屈曲形成されている一方、該土踏まず部よりも靴長方向後方の踵側の部位では、該凹条及び凸条は、靴幅方向両側部が爪先側に寄った平面視への字状に屈曲形成されている、構成となすことが望ましい。   Further, in the central region of the lower surface of the outer sole, in the portion on the toe side ahead of the arch portion in the shoe length direction, the concave line and the convex line are in a plan view in which the central part in the shoe width direction is close to the toe side. On the other hand, at the heel side part behind the arch part, the concave and convex ridges are seen in a plan view in which both sides in the shoe width direction are close to the toe side. It is desirable that the structure be bent in a letter shape.

本発明に係るシューズによれば、合成ゴム中にガラス繊維が混入された各領域は、氷面や圧雪面を歩行した際に、その混入された繊維が氷面や圧雪面に食い込んでグリップ力を確保し、特に内足部領域と外足部領域とに配設されたガラス繊維混入ゴムは、その靴底面に形成される凸状の突出面が平坦で広い面積となっているので、主に氷面や圧雪面でのグリップ力の確保に優れたものとなっている。一方、中央部領域に配設されたガラス繊維混入ゴムは、その靴底面の形状が、靴幅方向に延びる複数の凹条及び凸条を有して波状に形成されている。このため、特に圧雪されていない雪面上を歩行した際には、当該中央部領域の凸条が雪面に食い込みつつ雪が踏み締められるため、その歩行時のグリップ力の確保に優れたものとなって、防滑機能を発揮する。従って、氷面や圧雪面などの凍結面上での歩行時に十分なグリップ力が得られると共に、未圧雪の雪面上での歩行時にも十分なグリップ力が得られて、靴底の滑動を可及的に防止することができ、もって凍結面や雪面での歩行性の可及的な向上を図ることができる。   According to the shoe of the present invention, each region in which the glass fiber is mixed in the synthetic rubber has a grip force when the mixed fiber bites into the ice surface or the snow pressure surface when walking on the ice surface or the snow pressure surface. In particular, the glass fiber-mixed rubber disposed in the inner foot region and the outer foot region has a flat and large area on the convex surface formed on the bottom of the shoe. In addition, it has excellent grip on ice and snow. On the other hand, the glass fiber-mixed rubber disposed in the central region is formed in a wavy shape with a plurality of concave and convex ridges extending in the shoe width direction. For this reason, when walking on a snow surface that is not compressed, the ridges in the central area bite into the snow surface and the snow is stepped on, so it is excellent in securing grip force during walking. And demonstrates anti-slip function. Therefore, it is possible to obtain a sufficient grip force when walking on a frozen surface such as an ice surface or a compressed snow surface, and also to obtain a sufficient grip force when walking on a snow surface of uncompressed snow, and to slide the shoe sole. It is possible to prevent as much as possible, and to improve the walking ability on the frozen surface and the snow surface as much as possible.

以下に、本発明に係るシューズの好適な実施の形態について、ウォーキングシューズを例示して添付図面に基づき詳述する。図1は本発明に係るシューズの靴底を示す裏面図であり、図2(a)は図1に示す靴底を内足側から見た側面図、同図(b)は図1に示す靴底を外足側から見た側面図、図3は本発明に係るシューズの靴底を示す平面図、図4は図1及び図3中のIV−IV線にて示す靴長方向の縦断面図である。   Hereinafter, a preferred embodiment of a shoe according to the present invention will be described in detail with reference to the accompanying drawings, taking a walking shoe as an example. FIG. 1 is a back view showing a shoe sole of a shoe according to the present invention, FIG. 2 (a) is a side view of the shoe sole shown in FIG. 1 viewed from the inner foot side, and FIG. FIG. 3 is a plan view showing the shoe sole of the shoe according to the present invention, and FIG. 4 is a longitudinal section in the shoe length direction indicated by line IV-IV in FIGS. FIG.

図1、図2に示すように、このウォーキングシューズ2の底面、つまり接地時の踏み面には合成ゴム製のアウターソール4が設けられている。そして、図3、図4に示すように、このアウターソール4の上面には、発泡ポリウレタンやEVA等の衝撃吸収性に優れた軟質弾性体製のミッドソール6が貼り合わされて靴底8が形成されている。そして、当該アウターソール4の周縁には、上方に立ち上がってミッドソール6の上面よりも上方に突出する立ち上がり部4aが形成されており、この立ち上り部4aに図外のアッパー部材の下縁部が一体的に貼り付けられてシューズ2が形成されるようになっている。   As shown in FIGS. 1 and 2, an outer sole 4 made of synthetic rubber is provided on the bottom surface of the walking shoe 2, that is, on the tread surface at the time of ground contact. As shown in FIGS. 3 and 4, on the upper surface of the outer sole 4, a midsole 6 made of a soft elastic body excellent in shock absorption such as polyurethane foam and EVA is bonded to form a shoe sole 8. Has been. A rising portion 4a that rises upward and protrudes upward from the upper surface of the midsole 6 is formed at the peripheral edge of the outer sole 4, and a lower edge portion of the upper member that is not shown in the drawing is formed on the rising portion 4a. The shoes 2 are formed by being integrally bonded.

ここで、図3、図4から分かるように、上記ミッドソール6の上面には、爪先側に位置する足指の第3関節部周辺のボール部相当部分(踏みつけ部分)に凹部9aが形成されており、この凹部9aには当該ミッドソール6よりも軟質な発泡樹脂製のクッション材10aが設けられている。また、上記ミッドソール6の上面には、踵側に位置する踵相当部分にも凹部9bが形成されており、この凹部9bにも当該ミッドソール6よりも軟質な発泡樹脂製のクッション材10bが設けられている。   Here, as can be seen from FIGS. 3 and 4, a recess 9 a is formed on the upper surface of the midsole 6 in a portion corresponding to the ball portion (stepping portion) around the third joint portion of the toe located on the toe side. A cushioning material 10a made of foamed resin that is softer than the midsole 6 is provided in the recess 9a. Further, a concave portion 9b is formed on the upper surface of the midsole 6 at a portion corresponding to the heel located on the heel side, and a cushioning material 10b made of foamed resin softer than the midsole 6 is also formed in the concave portion 9b. Is provided.

また、図2と図4とから分かるように、ミッドソール6とアウターソール4とからなる靴底8の土踏まず部12は、下面側が上方に凹まされてアーチ状に湾曲形成されている。そして、このアーチ状の土踏まず部12におけるミッドソール6の上面には、図3、図4に示すように、繊維強化樹脂シートからなる上部補強シート14が貼着されている。即ち、この実施形態では、当該上部補強シート14は、土踏まず部12の爪先側端部から踵側端部にかけての範囲にのみ配設されており、上記クッション材10a,10bは上部補強シート14よりも爪先側と踵側との2箇所に位置されて、踵部位と足指のボール部相当部分との足裏の踏み付け部分に配設されている。なお、当該繊維強化シートにはカーボン繊維、ガラス繊維、アラミド繊維、ケブラー繊維等を用いた繊維強化樹脂シートを採用し得る。   As can be seen from FIGS. 2 and 4, the arch portion 12 of the shoe sole 8 composed of the midsole 6 and the outer sole 4 is curved in an arch shape with the lower surface side recessed upward. And the upper reinforcement sheet | seat 14 which consists of a fiber reinforced resin sheet is affixed on the upper surface of the midsole 6 in this arch-shaped arch part 12 as shown in FIG. That is, in this embodiment, the upper reinforcing sheet 14 is disposed only in a range from the toe side end portion to the heel side end portion of the arch portion 12, and the cushion materials 10 a and 10 b are more than the upper reinforcing sheet 14. Also, it is located at two locations on the toe side and the heel side, and is disposed on the foot stepping part between the heel part and the ball part corresponding to the toe. Note that a fiber reinforced resin sheet using carbon fiber, glass fiber, aramid fiber, Kevlar fiber, or the like can be adopted as the fiber reinforced sheet.

また、図3、図4から分かるように、ミッドソール6とアウターソール4との間の土踏まず部12にも上記繊維強化樹脂シートと同材料からなる下部補強シート16が貼着されて介在されている。つまりミッドソール6の土踏まず部12は、その上下面が上部補強シート14と下部補強シート16との2枚の繊維強化樹脂シートで挟まれたサンドイッチ構造となっている。なお、この実施形態では上部補強シート14と下部補強シート16とには同一材料の繊維強化樹脂シートを用いているが、異種材料からなる繊維強化樹脂シートを組み合わせて用いる様にしても良い。また、本実施形態では、図1に示すように、アウターソール4の土踏まず部12には、下部補強シート16を視認できるように窓部18が開口形成されており、この窓部18には下部補強シート16の表面を覆う透明な保護カバー部材20が貼着されている。   As can be seen from FIGS. 3 and 4, a lower reinforcing sheet 16 made of the same material as that of the fiber reinforced resin sheet is stuck and interposed also on the arch portion 12 between the midsole 6 and the outer sole 4. Yes. In other words, the arch portion 12 of the midsole 6 has a sandwich structure in which the upper and lower surfaces are sandwiched between two fiber reinforced resin sheets of the upper reinforcing sheet 14 and the lower reinforcing sheet 16. In this embodiment, the upper reinforcing sheet 14 and the lower reinforcing sheet 16 are made of fiber reinforced resin sheets made of the same material. However, fiber reinforced resin sheets made of different materials may be used in combination. In the present embodiment, as shown in FIG. 1, a window 18 is formed in the arch portion 12 of the outer sole 4 so that the lower reinforcing sheet 16 can be visually recognized. A transparent protective cover member 20 that covers the surface of the reinforcing sheet 16 is attached.

ところで、図1に示すように、アウターソール4はその底面に、合成ゴム中にガラス繊維を混入させている複数の領域A,B,C,D,Eが配されて形成されている。また、当該ガラス繊維はその繊維長方向がソール厚み方向に配向されている。ここで、前記領域A,B,C,D,Eは大きく分けると、靴幅方向の内足部に位置した内足部領域Aと中央部に位置した中央部領域Bと外足部に位置した外足部領域C、並びに爪先部の前端に位置した爪先前端部領域D、踵部の後端に位置した踵後端部領域Eとの5つの部位に区分けされて配設されている。そして、領域A,B,Cにあっては、さらに靴長方向に沿って複数に分割されている。即ち、当該実施形態では、図1から分かるように、内足部領域Aと外足部領域Cにあっては、3分割形成されて設けられており、中央部領域Bにあっては2分割形成されて設けられている。   By the way, as shown in FIG. 1, the outer sole 4 is formed with a plurality of regions A, B, C, D, and E in which glass fibers are mixed in synthetic rubber on the bottom surface thereof. Moreover, the glass fiber has the fiber length direction oriented in the sole thickness direction. Here, the regions A, B, C, D, and E are roughly divided into an inner foot region A positioned at the inner foot portion in the shoe width direction, a central region B positioned at the central portion, and a position at the outer foot portion. The outer leg region C, the toe front end region D located at the front end of the toe portion, and the heel rear end region E located at the rear end of the heel portion are divided and arranged. And in area | region A, B, C, it is divided | segmented into plurality along the shoe length direction further. That is, in this embodiment, as can be seen from FIG. 1, the inner foot region A and the outer foot region C are divided into three parts, and the central region B is divided into two parts. It is formed and provided.

また、中央部領域Bと爪先前端部領域Dと踵後端部領域Eとにおいて使用される合成ゴムと、内足部領域Aと外足部領域Cとにおいて使用される合成ゴムとには、相互に比較して硬度の異なるものが採用されている。即ち、内足部領域Aおよび外足部領域Cとには、硬度が低くて柔らかいもの(例えばJIS硬度Aが35〜50°のもの)が使用される。一方、中央部領域Bと爪先前端部領域Dと踵後端部領域Eとには、硬度が高くて硬いもの(例えばJIS硬度Aが55〜70°のもの)が使用される。   In addition, the synthetic rubber used in the central region B, the toe front end region D and the heel rear end region E, and the synthetic rubber used in the inner foot region A and the outer foot region C, Those having different hardness compared to each other are employed. That is, for the inner foot region A and the outer foot region C, those having low hardness and softness (for example, those having a JIS hardness A of 35 to 50 °) are used. On the other hand, for the center region B, the toe front end region D, and the heel rear end region E, those having a high hardness (for example, those having a JIS hardness A of 55 to 70 °) are used.

即ち、上記各領域A,B,C,D,Eに配設されているガラス繊維の混入された合成ゴムは、氷面や圧雪面を歩行した際に、荷重によって合成ゴムが圧縮変形すると、その内部に混入された繊維の先端が突出して氷面や圧雪面に突き刺さって食い込み、これによりグリップ力を確保して防滑機能を発揮するようになっている。そして、内足部領域Aと外足部領域Cとにあっては、特に氷面や圧雪面での防滑機能を高めるべく、上記の如くその合成ゴムには軟質なものを使用している。つまり、荷重による合成ゴムの圧縮変形が大きくなるようにして、相対的に変形し難いガラス繊維の先端が突出し易くしている。   That is, when the synthetic rubber mixed with the glass fiber disposed in each of the regions A, B, C, D, and E walks on the ice surface or the snow pressure surface, when the synthetic rubber is compressed and deformed by a load, The tip of the fiber mixed inside protrudes and penetrates into the ice surface or the snow pressure surface, thereby securing a grip force and exerting an anti-slip function. In the inner foot region A and the outer foot region C, as described above, a soft material is used for the synthetic rubber in order to enhance the anti-slip function on the ice surface and the snow pressure surface. That is, the compression deformation of the synthetic rubber due to the load is increased, and the tip of the glass fiber that is relatively difficult to deform is easily protruded.

また、当該領域A,Cの部分にあっては、氷面や圧雪面での防滑機能をさらに高めるために、そのガラス繊維が混入されている合成ゴムを、広い面積で氷面や圧雪面等の表面に接触させてより十分なグリップ力が得られるようにしている。つまり、当該領域A,Cでは、溝幅の狭い凹条26を靴幅方向に形成することで、相対的に凸条28の突出面28aを広くし、かつ当該突出面28aは平坦に形成した靴底形状となしている。   Further, in the areas A and C, in order to further enhance the anti-slip function on the ice surface and the snow pressure surface, the synthetic rubber mixed with the glass fiber is used in a wide area such as the ice surface and the snow pressure surface. It is made to contact with the surface of this so that a sufficient grip force can be obtained. In other words, in the regions A and C, by forming the narrow groove 26 with a narrow groove width in the shoe width direction, the protruding surface 28a of the protruding line 28 is relatively widened, and the protruding surface 28a is formed flat. It has a sole shape.

一方、図1に示すように、アウターソール4の下面における前記中央部領域Bと爪先前端部領域Dと踵後端部領域Eとの各部位の靴底形状は、圧雪されていない雪面上を歩行した際にも、十分なグリップ力が得られる靴底形状に形成されている。即ち、これら中央部領域Bと爪先前端部領域Dと踵後端部領域Eとには、複数の凹条22と凸条24とがそれぞれの溝幅と突出幅とを大きくされて靴幅方向に延びて形成されている。つまり、靴幅方向に延びる凹・凸条22,24によって、靴底は靴長方向に沿って大きく波打つ形状になっている。このため、特に圧雪されていない雪面上を歩行した場合には、当該靴幅方向に延びる凸条24が踏み締められた雪面に食い込んで前後方向へのグリップ力を確保し、防滑機能を発揮するようになっている。   On the other hand, as shown in FIG. 1, the sole shape of each part of the center region B, the toe front end region D, and the heel rear end region E on the lower surface of the outer sole 4 is on a snow surface that is not compressed. The shoe is shaped like a shoe so that a sufficient grip can be obtained even when walking. That is, in the center region B, the toe front end region D, and the heel rear end region E, a plurality of concave strips 22 and convex strips 24 have their respective groove widths and projecting widths increased to increase the shoe width direction. It is extended and formed. That is, the shoe sole has a shape that undulates along the shoe length direction by the recesses / ridges 22 and 24 extending in the shoe width direction. For this reason, especially when walking on a snow surface that is not compressed, the ridges 24 extending in the shoe width direction bite into the snow surface that has been stepped on to secure a grip force in the front-rear direction and exhibit an anti-slip function. It is supposed to be.

さらに、図1に示すように、上記中央部領域Bにおける凹・凸条22,24は、その中央部領域Bでの防滑機能をより向上させるために、土踏まず部12よりも靴長方向前方の爪先側の部位では、靴幅方向の中央部が爪先側に寄った平面視への字状に屈曲形成される一方、土踏まず部12よりも靴長方向後方の踵側の部位では、当該凹条22及び凸条24は、上記とは逆向きに、靴幅方向両側部が爪先側に寄った平面視への字状に屈曲形成されている。   Further, as shown in FIG. 1, the concave and convex strips 22 and 24 in the central region B are more forward in the shoe length direction than the arch portion 12 in order to further improve the slip prevention function in the central region B. In the toe side portion, the center portion in the shoe width direction is bent and formed in a shape of a plan view near the toe side, while in the heel side portion behind the arch portion 12 in the heel side portion, 22 and the ridges 24 are bent in the shape opposite to the above in the shape of a plan view in which both sides in the shoe width direction approach the toe side.

即ち、中央部領域Bにおける前方の爪先側では、未圧雪面を歩行した時にその雪を踏み締めて凹条22内に食い込ませて捕らえた雪を、前進する際や上り坂等で、側方に逃げてしまうのを可及的に防止し得る形状となしており、これにより前方へのグリップ力をより一層確保し得るようにしている。一方、中央部領域Bにおける後方の踵側では、爪先側と逆向き形状となすことで、凹条22内に食い込ませて捕らえた雪を、下り坂等で側方に逃げてしまうのを可及的に防止し得る形状となしており、これにより靴底8の前方への滑動を抑制するグリップ力を確保し得るようにしている。   That is, on the front toe side in the central region B, when walking on the unstressed snow surface, the snow caught by stepping on the snow 22 and being caught in the concave strip 22 is moved to the side when moving forward or uphill. It has a shape that can prevent the escape as much as possible, thereby further securing a grip force toward the front. On the other hand, the rear heel side in the central region B has a shape opposite to the toe side, so that it is possible to escape snow trapped in the recess 22 to the side on a downhill or the like. It has a shape that can be prevented as much as possible, so that a grip force that suppresses the forward sliding of the shoe sole 8 can be secured.

また、図4に示すように、中央部領域Bに形成される凸条24は、土踏まず部12よりも爪先側の部位では、爪先側面24aが傾斜面に形成され、踵側面がほぼ鉛直面に形成されており、その爪先側面24aの傾斜方向は隣接する凹条22の溝幅が開放側で拡開する方向になっている。即ち、凹条22の溝幅が開放側で拡開しているので、未圧雪面を踏みしめた時に凹条22内に食い込ませて捕らえた雪は、靴を雪面から持ち上げた際に当該凹条22から離脱し易くなっており、当該凹条22内に詰まったままになってしまうことを可及的に防止できるようになっている。このため歩行を進めても、その1歩毎にしっかりと凹・凸条22,24で雪面を捕らえ続けることができ、しかも凸条24の踵側面24bは鉛直となっているので、前進時の前方へのグリップ力を損なうことがない。   Further, as shown in FIG. 4, the protrusion 24 formed in the central region B has a toe side surface 24 a formed in an inclined surface and a heel side surface in a substantially vertical surface in a portion closer to the toe side than the arch portion 12. It is formed, and the inclination direction of the toe side surface 24a is a direction in which the groove width of the adjacent recess 22 expands on the open side. That is, since the groove width of the groove 22 is widened on the open side, the snow caught by being caught in the groove 22 when the unstressed snow surface is stepped on is not removed when the shoe is lifted from the snow surface. It becomes easy to detach | leave from the strip | line 22, and it can prevent as much as possible that it becomes clogged in the said concave strip 22 now. For this reason, even if walking is advanced, the snow surface can be kept firmly captured by the concave and convex ridges 22 and 24 for each step, and the ridge side surface 24b of the convex ridge 24 is vertical. There is no loss of gripping force toward the front.

一方、図4に示してあるように、中央部領域Bに形成される凸条24は、土踏まず部12よりも踵側の部位では、爪先側面24aがほぼ鉛直面に形成され、踵側面24bが傾斜面に形成されており、その踵側面24bの傾斜方向は隣接する凹条22の溝幅が開放側で拡開する方向になっている。即ち、上記と同様に、凹条22の溝幅が開放側で拡開しているので、未圧雪面を踏みしめた時に凹条22内に食い込ませて捕らえた雪は、靴を雪面から持ち上げた際に当該凹条22内から離脱し易くなっており、当該凹条22内に詰まったままになってしまうことを可及的に防止でき、1歩毎にしっかりと凹・凸条22,24で雪面を捕らえ続けることができる。そして凸条24の爪先側面24aは鉛直となっているので、下り坂等において前方への靴底8の滑動を抑制するグリップ力を確保できるようになっている。   On the other hand, as shown in FIG. 4, the ridge 24 formed in the central region B has a toe side surface 24a formed in a substantially vertical surface at a heel side portion from the arch portion 12, and a heel side surface 24b It is formed in the inclined surface, The inclination direction of the collar side surface 24b is a direction where the groove width of the adjacent groove 22 expands on the open side. That is, as described above, since the groove width of the recess 22 is widened on the open side, the snow caught in the recess 22 when stepping on the unstressed snow surface lifts the shoe from the snow surface. Can be easily removed from the inside of the groove 22 and can be prevented from being stuck in the groove 22 as much as possible. You can continue to catch the snow surface at 24. And since the toe side surface 24a of the protruding item | line 24 is vertical, the grip force which suppresses the sliding of the shoe sole 8 ahead on a downhill etc. can be ensured now.

また、内足部領域Aと外足部領域Cとの合成ゴムには軟質なものが使用される一方、中央部領域Bの合成ゴムには硬質のものが使用されているので、未冠雪の乾燥した路面上等を歩行した際には、荷重の多くは中央部領域Bの硬質な合成ゴムで負担されることになる。よって軟質な合成ゴムが使用されている内足部領域Aと外足部領域Cとに生じる摩耗を可及的に抑制して耐久性を高めることができ、靴の寿命の延命化を図ることができるようになっている。   Further, the soft rubber is used for the synthetic rubber of the inner foot region A and the outer foot region C, while the hard rubber is used for the synthetic rubber of the central region B. When walking on a dry road surface or the like, most of the load is borne by the hard synthetic rubber in the central region B. Therefore, the wear generated in the inner foot region A and the outer foot region C where soft synthetic rubber is used can be suppressed as much as possible to increase durability, and the life of the shoe can be extended. Can be done.

本発明は上記実施例にて説明したウォーキングシューズだけでなく、日常のタウンユースのシューズやジョギングシューズの他、トレッキングシューズや登山靴等、冠雪面や凍結面の上を歩行する可能性のあるシューズ全般にも適用することができ、その利用範囲は広い。   In addition to the walking shoes described in the above embodiment, the present invention may walk on snow-covered surfaces or frozen surfaces, such as daily town use shoes and jogging shoes, as well as trekking shoes and mountain climbing shoes. It can be applied to shoes in general, and its range of use is wide.
