Systems and methods are described for a shoe sole for relieving pressure from a wearer's metatarsal heads. In one aspect, a shoe sole comprises a shoe outer sole comprising a shaft region, a ball region, and a toe region. The shaft region underlies metatarsal shafts of the wearer and comprises a first lower surface, the ball region underlies metatarsal heads of the wearer and comprises a second lower surface, and the toe region underlies phalanges of the wearer and comprises a third lower surface. The second lower surface is raised relative to the first lower surface and the third lower surface.

Device suitable for being integrated in footwears soles, acting as cushioning, energy dissipation and stabilization means, including: a cushioning element made of a first material having a viscoelastic behavior; a conditioning element positioned under the cushioning element and made of a second material having a viscoelastic behavior; and a containing element positioned above the cushioning element and covering also the conditioning element. The cushioning element having first empty regions that are first through holes and second through holes and channels to pushing out the air when the device is subjected to a compression load.

Provided is a shoe article with an arch spring. A shoe article with an arch spring comprises an arch part 13 contacting a side part of a foot middle part and having a convex curved shape upwardly; and an arch spring 20, 30 formed at the arch part 13, wherein at least one part of the arch spring 20, 30 has an elastic property for moving in an up and down direction and being recovered in an original shape.

Insole includes a base having a shape for placement onto a sole of or in a shoe, and which base has at least one cavity extending inward from a lower surface over only a part thereof, and surrounded peripherally by the base, such that over a remaining part, the lower surface is a lowermost surface of the insole. A mesh is attached to an upper surface of the base and forms an uppermost surface of the insole. An air cushion is present in each cavity, and includes a sealing structure and lightweight foam pieces held in each cavity by the sealing structure such that when in the respective cavity, each air cushion is a lowermost surface of the insole. The sealing structure may be a plastic membrane attached to the base around a periphery of the respective cavity or a plastic membrane that surrounds the foam pieces.

A dress shoe includes a flexible upper structure with stretchy lining and outside layers and a zonal-structured cloth layer therebetween to enable elasticity while maintaining structure; a cushioned insole with a three-point support system under the toe crest, the arch, and the heel; and a mixed material insole and outsole to prevent slipping during walking and standing.

A shoe-pad, shoe and hallux orthotic device, the shoe-pad is configured for correcting and preventing deformity of a hallux, the shoe-pad includes a shoe-pad body, a first orthotic portion, and a second orthotic portion; the first orthotic portion and the second orthotic portion are protruded from a surface of the shoe-pad body and spaced from each other, and the first orthotic portion and the second orthotic portion are staggered from each other in a front-back direction. The first orthotic portion and the second orthotic portion are spaced from each other on the shoe-pad body, and the first orthotic portion and the second orthotic portion are staggered from each other in a front-back direction, the structure is simple, the production and using are convenient, the hallux valgus can be corrected and prevented without a surgery, and the suffering and financial burden of the patients are reduced.

A shoe sole includes a body portion and a heel holding portion. The heel holding portion is located opposite to a ground contact surface of the body portion and holds a heel portion of a foot at least from a medial foot side. The body portion includes a low hardness portion and a high hardness portion. The high hardness portion is a foam material harder than a foam material of the low hardness portion. The heel holding portion is a resin harder than the foam material of the low hardness portion and the foam material of the high hardness portion. On the medial foot side in a rear foot portion, the low hardness portion is located between the heel holding portion and the high hardness portion in an up-down direction.

A footwear kit, comprising: left and right items of footwear; left and right forefoot inserts receivable in the left and right footwear items, respectively, so as to tighten the fit thereof to a wearer; a fitting guide directing that, should the wearer have an orthotic for either or each foot, a said forefoot insert be arranged such that it underlies the orthotic in the footwear item for that foot if the fit of that footwear item with only the orthotic therein is loose.
