Definitions

  • the present invention relates to a shoe with an improved fit property accommodating the movement of the heel during exercises including walking and running, and more particularly to a shoe with an improved fit property accommodating the movement of the heel from foot-flat to take-off.
  • the first patent document discloses an upper structure provided with an outer upper wrapping around an upper main body.
  • An elastic area is provided between the front portion and the heel portion of the upper main body.
  • This upper main body is such that the mouth (the top line) expands when putting on and the mouth shrinks when worn, and therefore a good fit at the heel may be obtained.
  • the second patent document discloses a hard stirrup covering the back surface and the opposite side surfaces of the calcaneal bone.
  • the hard stirrup is formed by a hard plastic containing reinforced fiber. Such a stirrup may be useful in suppressing the rotation of the navicular bone.
  • the third patent document discloses a generally V-shaped stirrup.
  • the stirrup may support the middle foot, particularly, suppress inadvertent movements of the navicular bone.
  • the fourth patent document discloses a shoe including a sock inner and a strap.
  • the sock inner is formed by an elastic material, and the strap may fit the flexible sock inner to the heel.
  • FIG. 16 shows a medial side view of the foot in a standing position
  • FIG. 17 shows a medial side view in a push-off position.
  • the points O1 to O12 are markers attached to the surface of the foot, and values in the figures denote dimensions between these points in millimeters.
  • a comparison between the standing position and the push-off position shows that the lower portion (the distance between the point 03 and the point O11, the distance between the point 03 and the point O12) and the rear portion (the distance between the point O11 and the point O12) of the heel of the foot shrink about the malleolus, or the like, as the center. The shrinking of the heel will lead to slippage between the upper and the foot.
  • the heel of the foot shrinks by about 3 mm toward the front side, whereas the heel portion of the upper surface of the sole will not shrink so much. Therefore, even if the upper is formed so that the heel portion of the upper stretches, whereby the rear end of the upper moves toward the rear end of the heel, the fit property of the heel portion will not improve so much because the upper is restricted by the sole.
  • the upper main body disclosed in the first patent document has its lower portion connected integrally with the sole from the front foot to the rear foot. Therefore, in the heel portion of the upper main body, when the stretchable upper portion shrinks, the non-stretchable lower portion may expand in the foot width direction. Therefore, the heel fit will be deteriorated.
  • the front portion of the stirrup disclosed in the second patent document extends diagonally downward, and the stirrup does not cover the portion right behind the malleolus. Therefore, a tensile force acts on the hard stirrup in a diagonally forward direction. Therefore, while the stirrup may be useful in suppressing the rotation of the navicular bone, it will not be so useful in making the upper side surface of the upper fit to the upper side surface of the heel below the malleolus.
  • a portion of the stirrup is accommodated in a pocket of the upper and the stirrup is placed below the upper edge of the upper in the rear foot portion, and therefore it is not possible to press the upper edge portion of the upper forming the mouth against the side surface of the foot.
  • the uppers disclosed in the third and forth patent documents are integral with the sole from the front foot to the rear foot. Therefore, the fastening force of the shoe lace will unlikely be localized at the mouth (top line), the portion of the upper near the mouth will unlikely conform to the side surface of the foot, and the heel portion of the upper will likely expand in the foot width direction.
  • a shoe according to an embodiment of the present invention is a shoe with an improved heel fit including: a main upper being continuous from a tip of a toe to side surfaces of a heel and covering the toe and a medial side and a lateral side of a foot; a sub-upper formed by a separate member from the main upper, covering the heel in the main upper and not covering a distal head of a metatarsal bone; a shoelace for fitting the main upper and the sub-upper to the foot; and a sole to which secured edge portions of the main upper and the sub-upper along lower edges thereof are secured, wherein: the main upper includes a notch covered by a tongue, and first eyelet holes which are arranged in two rows along the notch and through which the shoelace passes; the sub-upper includes portions covering a medial side surface and a lateral side surface of a talus bone, and a medial side surface, a lateral side surface and a back surface of a calcaneal
  • the sub-upper only covers the heel and is , not secured to the sole in the tread area, and it therefore easily follows the flexion of the foot.
  • the sub-upper is a separate member from the main upper, and wraps around the heel in the main upper. Therefore, even if the main upper expands at the mouth in the foot width direction, the main upper will not hinder the upper portion, particularly the layered portion including the cushioning material, of the sub-upper, which is not attached to the main upper, from fitting to the upper side surface of the foot by virtue of the fastening force of the shoelace.
  • the eyelet portion bends as it engages with the main upper at the through hole, the fastening force of the shoelace drawing toward the center of the foot is turned into a tensile force in the forward direction. Therefore, on the upper side surface of the foot, a forward tensile force acts on the upper portion, particularly the layered portion, of the sub-upper, whereby the upper portion, particularly the layered portion, of the sub-upper fits to the side surface of the foot.
  • the main upper presses the front extension of the sub-upper onto the side surfaces of the foot in an inward direction by virtue of the fastening force of the shoelace.
  • the upper portion of the sub-upper curves in conformity with the horizontal cross section of the foot, thereby fitting the upper portion, particularly the layered portion, of the sub-upper to the upper side surface of the foot. That is, while the upper portion of the sub-upper being pulled forward via the eyelet portion has a U-shaped horizontal cross section, it takes a shape that is gradually curved toward the center of the foot as it extends from directly below the malleolus toward the front side due to the pressing force of the main upper, thereby fitting to the upper side surface of the foot.
  • the layered portion is optional. Nevertheless, if the layered portion is provided, the layered portion including the cushioning material is likely to be pressed against the upper side surface of the foot. Therefore, if the layered portion is provided, the fit property is high.
  • the layered portion may include a layer that is attached to and layered on one of the front surface and the reverse surface of the base material forming the sub-upper, or may include the cushioning material sandwiched and layered between the inner skin and the outer skin (the base material).
  • the front extension extends forward past the secured edge portion of the sub-upper, and a front end of the secured edge portion of the sub-upper is placed posterior to a front end of a calcaneal bone, wherein the front extension has a non-secured edge portion along a lower edge thereof extending diagonally rearward toward the front end of the secured edge portion of the sub-upper.
  • the front end of the secured edge portion along the lower edge is located posterior to the front end of the front extension, and it does not hinder a tensile force from acting in the front-back direction on the layered portion when the front extension is pulled forward. Therefore, the layered portion is likely to fit to the upper side surface of the foot.
  • the sub-upper includes an exposed portion, which is not accommodated in the main upper, extending from directly under a rear end of the medial malleolus and the lateral malleolus to a back surface of the heel; and the main upper covers a lower portion of the calcaneal bone from the back surface.
  • the main upper covers the lower portion of the calcaneal bone from the back surface, and the main upper has a high stability for holding the heel. Therefore, the rigidity of the sub-upper can be reduced, and the fit of the sub-upper will therefore be enhanced.
  • the exposed portion of the sub-upper that is exposed from the main upper will not deform in response to deformation of the main upper. Therefore, the upper portion of the sub-upper will not expand in the foot width direction, but will remain fitted to the upper side surface of the foot.
  • the main upper and the sub-upper are attached to each other on a back of the heel and are not attached to each other in the upper portion of the sub-upper directly below the malleolus and in an area in front of the upper portion of the sub-upper.
  • the uppers are not attached to each other.
  • the inner skin and the outer skin are formed by a flexible material so that the upper portion of the sub-upper stretches in a front-back direction when the shoelace is fastened.
  • the sub-upper including the flexible material layered on the cushioning material is not restricted by the main upper and is likely to conform to the side surface of the foot.
  • a counter formed by a synthetic resin which is harder than the layered portion and which has a U-shaped horizontal cross section is secured to the outer skin, over an area from the back surface to medial and lateral side surfaces of the heel, in a lower portion of the sub-upper away from an upper edge of the sub-upper so that the layered portion conforms to a side surface of the foot.
  • the hard U-shaped counter will not hinder the flexible cushioning material and the inner skin from conforming to the foot, and the hard counter helps the upper portion conform to the foot.
  • the front extension extends forward past a front end of the counter; and in medial-side and lateral-side areas anterior to the front end of the counter, the main upper presses the front extension against side surfaces of the foot by the fastening force of the shoelace.
  • the flexible front extension rather than the hard counter, is pressed against the side surface of the foot by the main upper. Therefore, the front extension is curved in conformity with the surface of the instep of the foot. This curving greatly increases the tensile force in the front-back direction acting on the layered portion.
  • the counter is placed along the layered portion of the sub-upper; the upper edge of the main upper extends diagonally downward in a rearward direction to a rear end of the heel; and the main upper covers a front end portion of the counter and does not cover a rear portion of the counter in the upper portion of the sub-upper.
  • the front end portion of the counter is pressed against the side surface of the foot by the main upper. Therefore, there is a great moment acting on the counter, and the counter can be pressed against the side surface of the foot even if it is a hard counter.
  • a shoe of the present embodiment includes a main upper 1, a sub-upper 2, a shoelace 3, and a sole 4.
  • the main upper 1 is continuous from the tip of the toe 9 to the back surface of the heel 8 shown in FIGS. 2 and 4 , and covers the toe and the medial side and the lateral side of the foot.
  • the sub-upper 2 shown in FIGS. 1 and 3 is formed by a separate member from the main upper 1 and is placed in the main upper 1, as will be described later.
  • the shoelace 3 is for making the main upper 1 and the sub-upper 2 fit to the foot F ( FIGS. 2 and 4 ).
  • FIGS. 6 and 7 the sock lining (sock liner) of the shoe has been removed.
  • a secured edge portion 1a at the lower edge of the main upper 1 is sewn and secured to the insole forming a part of the sole 4, and a secured edge portion 2a at the lower edge of the sub-upper 2 is sewn and secured to the insole.
  • the main upper 1 includes a notch 10 covered by a tongue 5, and first eyelet holes h1 to h3, h5 and h6 which are arranged in two rows along the notch 10 and through which the shoelace 3 passes.
  • the main upper 1 does not cover the lower end of the Achilles tendon T and covers the lower portion of the calcaneal bone B9 from the back surface.
  • a through hole 11 is formed on the medial side and the lateral side of the main upper 1 in the middle foot area.
  • An eyelet member (an example of an eyelet portion) 24 provided on the sub-upper 2 having the second eyelet hole h4 is inserted through each through hole 11, with the second eyelet hole h4 ( FIG. 8 ) exposed on the outside of the main upper 1 via the through hole 11, as will be described later.
  • the sub-upper 2 includes a lower portion 2d and an upper portion 2u above the lower portion 2d, and the lower portion 2d is covered by the main upper 1.
  • the rear portion of the tongue 5 and the upper portion 2u of the sub-upper 2 together form a mouth (top line) 6 through which the leg L comes out in an upward direction when the shoe is worn, and fit to the foot at the mouth 6.
  • the sub-upper 2 is in contact with the surface of the foot F on the side surfaces and the back surface thereof.
  • the sub-upper 2 is formed so as to cover at least a portion of the heel 8 that is posterior to the malleolus M.
  • the sub-upper 2 covers at least a portion of the medial side surface of the talus bone B8, the navicular bone B6 and the calcaneal bone B9.
  • the sub-upper 2 covers at least a portion of the lateral side surface of the talus bone B8, the cuboid bone B7 and the calcaneal bone B9.
  • the sub-upper 2 is designed so as to cover the heel 8 and not to cover the metatarsal bones B4 i .
  • B5 1 in FIG. 1 denotes the medial cuneiform bone.
  • the sub-upper 2 includes layered portions 20 and 29 in the upper portion 2u and the lower portion 2d.
  • the layered portions 20 and 29 each have a cushioning material 21 represented as a dotted area, layered with an inner skin 22 and an outer skin 23, with the cushioning material 21 sandwiched therebetween.
  • the cushioning material 21 may be, for example, a foamed resin or a foamed rubber as well as a non-woven fabric (felt), or the like, and serves to fit to the upper portion of the foot F ( FIGS. 2 and 4 ) in the upper portion 2u and the lower portion 2d of the sub-upper 2.
  • the thickness of the cushioning material 21 is such that the upper layered portion 20 is thicker than the lower layered portion 29, with the upper layered portion 20 bulging toward the surface of the foot F by virtue of the cushioning material 21.
  • the area of the upper layered portion 20 is dotted.
  • the upper layered portion 20 extends diagonally upward in a rearward direction from directly below the medial and lateral malleoli M so as to cover a lower portion of the Achilles tendon T at a level above the lower end of the lateral malleolus Ml.
  • the inner skin 22 and the outer skin 23 shown in FIGS. 13A and 13B are formed by a flexible material so that the upper portion 2u of the sub-upper 2 slightly stretches in the front-back direction when the shoelace 3 is fastened.
  • the material of the inner skin 22 and the outer skin 23 of the sub-upper 2 may be a fabric, a synthetic leather, or the like, used for the tongue 5, for example.
  • the inner skin 22 and the outer skin 23 are formed by a flexible material that is more stretchable than a portion of the main upper 1 that covers the side surface of the foot.
  • a heel counter 25 formed by a non-foamed synthetic resin which has a U-shaped horizontal cross section is secured to the outer skin 23.
  • the counter 25 is secured to the surface of the outer skin 23.
  • the counter 25 is secured to a lower portion of the sub-upper 2 away from an upper edge 2e of the sub-upper 2 so that the upper layered portion 20 conforms to the side surface of the foot F. That is, the counter 25 is placed along the layered portion 20 of the sub-upper 2.
  • an upper edge 1e of the main upper 1 extends diagonally downward in a rearward direction to the rear end of the heel 8 ( FIGS. 2 and 4 ).
  • the sub-upper 2 includes an exposed portion 26 that is not accommodated by the main upper 1, extending from directly below the rear end of the medial malleolus Mm and the lateral malleolus Ml to the back surface of the heel 8. Therefore, the main upper 1 covers the front end portion of the counter 25 in the upper portion 2u of the sub-upper 2, and does not cover the rear portion of the counter 25 in the upper portion 2u of the sub-upper 2, i.e., the exposed portion 26 of the sub-upper 2.
  • the upper portion 2u of the sub-upper 2 integrally includes front extensions 2f extending forward past the front end of the counter 25.
  • the front extensions 2f extend forward from directly below the medial and lateral malleoli Mm and Ml past the front end of the opposite side surfaces of the calcaneal bone B9.
  • the main upper 1 and the sub-upper 2 are bonded (attached) to each other in a lower portion of the back of the heel 8 so that they can move independently, and bonded (attached) to each other in an area of the sub-upper 2 covered by a roll-up portion 41 (a portion overlapping the upper) of the sole 4, while they are not bonded (attached) to each other in the upper portion 2u of the sub-upper directly below the malleolus M and in an area in front of the upper portion 2u. Therefore, the upper portion 2u including the front extensions 2f is not attached to the main upper 1, and will not deform in response to changes in the shape of the main upper 1. That is, even if the main upper 1 expands at the mouth, the sub-upper 2 will not expand.
  • the front extension 2f extends forward past the secured edge portion 2a of the sub-upper 2.
  • the front end of the secured edge portion 2a of the sub-upper 2 is placed posterior to the front end of the calcaneal bone B9. Therefore, the front extension 2f has a non-secured edge portion 2b along the lower edge thereof extending diagonally downward and rearward toward the front end of the secured edge portion 2a. At least a portion of the front extension 2f is covered by the upper 1.
  • the medial and lateral front extensions 2f each include a band-shaped eyelet member 24, separate from the main upper 1, secured (sewn) thereto.
  • the eyelet member 24 of FIG. 8 is formed in a loop shape, thereby forming the second eyelet hole h4 in the eyelet member 24 receiving the shoelace 3 passing through the loop.
  • the eyelet members 24 are drawn toward the center of the foot by the fastening force from portions 30 (dotted portions) of the shoelace 3 near the second eyelet holes h4.
  • the eyelet member 24 bends as it engages with the main upper 1 at the through hole 11, thereby changing the direction of the fastening force to pull the upper portion 2u including the front extension 2f of FIG. 12B in the forward direction X ( FIG. 10 ).
  • the main upper 1 is drawn toward the center of the foot by the fastening force from portions 31 (dotted portions) of the shoelace near one (h5) of the first eyelet holes h1 to h3, h5 and h6 shown in FIG. 8 that is posterior to the second eyelet hole h4. Therefore, portions of the front extensions 2f that are covered by the main upper 1 shown in FIGS. 1 and 3 are pressed against the upper side surface of the foot F ( FIGS. 2 and 4 ) in the direction of arrows 100 in FIG. 12C so as to be curved in conformity with the shape of the foot, thereby fitting the layered portion 20 including the cushioning material 21 to the upper side surface of the foot.
  • the cushioning material 21 fits to the upper side surface of the foot even in the push-off position, thereby obtaining a good fit despite the movement of the heel 8.
  • the medial side of the sub-upper 2 may cover a portion of the medial cuneiform bone B5 1 ( FIG. 1 ) or may cover a portion of the first metatarsal bone B4 1 ( FIG. 1 ), as indicated by one-dot-chain lines in FIG. 2 .
  • the lateral side of the sub-upper 2 does not cover the fifth metatarsal bone B4 5 in view of the wearability.
  • an eyelet portion through which the shoelace 3 can be inserted may be provided by forming a through hole using a resin or metal eyelet in the front extension 2f.
  • a plurality of second eyelet holes h4 may be provided on the medial side and/or the lateral side of the foot.
  • the present invention is applicable to shoes capable of providing a good fit accommodating the movement of the heel.
