The present invention provides an improved orthotic device adapted to be inserted into a high-heeled or raised-heel shoe and to receive a human foot thereon. The orthotic device may be operable to adhere to the sole of the shoe and may comprise a proximal contoured slope operable to prevent migration and increase acceptance of body weight at the heel of the wearer's foot and may comprise a distal contoured slope operable to support the arch of the wearer's foot, preventing the foot from sliding forward and focusing excessive painful pressure at the user's toes. The orthotic device may also have dual layers of adhesive material separated by a peel-away backing, and an inferior surface concavity with a channel allowing solvent to be used to dissolve the adhesive if the orthotic device needs to be repositioned or changed to a new shoe.

An insole for insertion into footwear includes a base, and an arch support located on an underside of the base layer, the arch support including a frame forming at least a portion of a perimeter of the arch support, and multiple ribs extend from a first side of the frame to a second side of the frame, wherein a first set of the ribs is raised relative to a second set of the ribs.

A pair of minimalist barefoot shoes has two shoe units. Each shoe unit has a shoe member, a medial arch pulling member, and a pressing member. The shoe member has a shoe body, a toe member, and a sole. The shoe body has a medial arch segment, an instep lateral segment, a receiving space, an opening, and an attachment layer. The medial arch pulling member is mounted on the shoe member and has a pulling segment and a connection layer. The pressing member is mounted on the shoe body and has a pressing segment and a combination layer. The pressing segment is attached securely to the shoe body, extends around an medial arch segment of the shoe body, and covers the first end of the medial arch pulling member.

A method for manufacturing an insole for a shoe. The method includes providing instructions to a person to attain a first pose; capturing a first three-dimensional image of a first foot of the person in the first pose; providing instructions to the person to attain a second pose, wherein the second pose is different from the first pose; capturing a second three-dimensional image of a second foot of the person in the second pose; generating a first three-dimensional model of the first foot from the first three-dimensional image; generating a second three-dimensional model of the second foot from the second three-dimensional model; manufacturing a first insole for the first foot based on the first three-dimensional model of the first foot; and manufacturing a second insole for the second foot based on the second three-dimensional model of the second foot.

Footwear for covering a foot of a wearer includes an outsole configured for supporting the foot of the wearer, an upper secured to the outsole and configured for covering the foot of the wearer, an insole located above the outsole within the upper, a midsole located above the outsole and below the insole and first and second laterally adjacent shanks located above the outsole and below the insole. The first shank angles forward and outward from the heel portion to a lateral side of the middle portion and the second shank angles forward and outward from the heel portion to a medial side of the middle portion to form an acute angle therebetween and provide balance and torsional stability for sides of the wearer's foot

A sole structure for a shoe that can secure cushioning properties and obtain a ground surface information is disclosed. The sole structure includes a first midsole having a plurality of first protrusions on a foot-sole-contact side, an outsole having a plurality of second protrusions on a ground surface side, and a second midsole disposed at a part of a region between the first midsole and the outsole and having a lower compressive rigidity than the first midsole. At least a part of the plurality of first protrusions of the first midsole is located at a position corresponding vertically to at least a part of the plurality of second protrusions of the outsole.

In some examples, a sole layer for a footwear includes a housing structure, a cell in the housing structure, a solid support inside the cell to maintain a shape of the cell, and an inlet to the cell to receive an injected material to dissolve the solid support.

An article of apparel, such as a sock or a shoe, is disclosed as having a foot-supporting area for extending adjacent to a plantar surface of a foot. The foot-supporting area has various zones of differing thickness that attenuate forces upon the plantar surface to different degrees. The apparel may be manufactured through a process that includes utilizing a force mapping device to obtain data relating to forces upon the plantar surface of the foot. The sock is then formed to have zones of different thickness located to correspond with the areas of the plantar surface subjected to different magnitudes of forces.

An orthotic support structure or shell may be used with footwear intrinsically or as a removable and transferable device. The footwear may be a sandal assembly including a sole, a strap and an orthotic shell. The strap is attached to the sole and configured to secure the sole against the foot. The orthotic shell is positioned within the sole and formed from a semi-rigid material. The orthotic shell includes a heel portion configured to support a heel region of the foot, and a midfoot portion connected to the heel portion and configured to support an arch region of the foot, the midfoot portion comprising an arched shank having a curved convex shape. The arched shank is configured to deflect under a downward force applied thereon which reactively rotates the heel portion toward the heel region of the foot.

The invention relates to an insole structure with decompression. It comprises an insole main body, and a guiding thin pad portion and a rear thin pad portion disposed on the insole main body, wherein the guiding thin pad portion provides capacity for an area given from metatarsophalangeal joints connected with a first phalanx and a first metatarsal till a fifth phalanx and a fifth metatarsal of the anterior sole, and the rear thin pad portion provides capacity for the calcaneus and have the first metatarsophalangeal joint stay at the lowest place while stepping.
