An inner sole structure for a sports shoe includes an upper sheet, a lower sheet below the upper sheet, and a wavy corrugated sheet interposed between the upper and lower sheets. The wavy corrugated sheet has at least two downwardly convex protrusions that form voids between the wavy corrugated sheet and the lower sheet, and that are in sliding contact with an upper surface of the lower sheet. The downwardly convex protrusions of the wavy corrugated sheet slide longitudinally along the lower sheet member when they are subjected to compressive deformation.

Inner sole structure for a sports shoe

A sole structurefor a shoe comprises an upper platethat is disposed on the upper side of the structureand that has upraised portionsprojecting upwardly form opposite side edge portions of the upper plate, a lower platedisposed below the upper plate, and a plurality of longitudinally separated connecting portionsandthat are disposed between the upper plateand the lower platesto form voidstherebetween and that elastically connect the upper platewith the lower plate. The upper end of the connecting portionextends upwardly to the side surface of the upraised portionof the upper plateand a projecting portionthat projects in the longitudinal direction is provided at the extension. The extensionand the projecting portionare fixedly attached to the side surface of the upraised portion

Sole structure for a shoe

The present invention provides a belt fastening means that can improve fittability of a shoe and that can equally tighten an upper of the shoe to a wearer's foot without hindering the movement of the foot. A belt fastening means for a shoe includes a first belt member disposed mainly on a lateral side portion of an upper and a second belt member disposed mainly on a medial side portion of the upper. The first and second belt members are located at nearly symmetrical positions with respect to an opening portion. A proximal end portion of the first belt member is connected to a sole on the lateral side and a distal end portion thereof extends over the opening portion. The first belt member extends in a direction nearly perpendicular to a ridge line of an instep portion as viewed from a lateral side of the shoe. A proximal end portion of the second belt member is connected to the sole on the medial side and a distal end portion thereof extends over the opening portion. The second belt member extends in a direction nearly perpendicular to the ridge line of the instep portion as viewed from a medial side of the shoe. The second belt member is formed with an elongated aperture into which the first belt member is inserted. The first and second belt members are releasably secured on the instep portion through hook and loop fastening materials.

Shoe with belt fastening means of improved fittablity

An athletic shoe includes a sole, an upper, a plurality of band-shaped members, and a fastening member. The upper has a toe portion, a heel portion, a forefoot portion and a lower periphery. The upper is secured to the sole and has a plurality of elongated through holes at regions except the toe portion and the heel portion. The band-shaped members are secured to the sole or the lower periphery of the upper and extend upwardly toward an instep of a foot of a shoe wearer. The fastening member is connected to each upper end of the band-shaped members.

Athletic shoe structure

The present invention relates to a tightening system for footwear, especially in athletic shoe, and is directed to improve the fittability, supportability and stability of the shoe. The athletic shoe of the present invention includes a supporting portion (Fs) for supporting the lateral side of a foot of a shoe wearer, a first fastening element of a loop shape that surrounds the periphery of the calcaneus (f ) of the foot, and a second fastening element of a loop shape that is provided integrally with the supporting portion (Fs). The supporting portion(Fs) extends from the position in the vicinity of the head of the metatarsus on the lateral side of the foot over the rear portion of the calcaneus of the foot to the medial side. The first fastening element, which is integrated with the terminus (Fs&prime;) of the supporting portion (Fs), extends upwardly to the position corresponding to the navicular (f ) on the medial side, and passes over the instep above the navicular (f ), and returns to the lateral side of the foot and to the calcaneus lateral side of the supporting portion (Fs). The second fastening element extends from the medial side to the lateral side on the rear side of the base position of the proximal phalanx (f ) of the foot. The first and second fastening elements include medial side, lateral fastening elements (F &prime;), (F &prime;) that are provided on the lateral side, and joining parts that join the medial fastening elements to the corresponding lateral fastening elements.
