A smart shoe has a height-adjustable heel having a plurality of co-axially oriented, concentric cylindrical wall sections of progressively different diameters comprising a skeleton framework. The wall sections are extendable from a collapsible position wherein the wall sections substantially completely overlap in an axial direction to an extended position wherein the walls sections are extended in an axial direction. Heel height is determined by the number of uncollapsed wall sections. A controller element provides incremental heel height adjustments through the sequential collapse of one wall section at a time starting with the uppermost wall section. The smart shoe includes reversibly expandable components for automatically modifying its width, length, and arch support height to provide an optimal fit of both shoes comprising the pair of smart shoes at every selected heel height.

An orthopedic walking boot includes a housing configured to encompass at least a user's foot, a mechanically adjustable ramp insert including a ramp surface and disposed in the housing, an adjusting mechanism configured to adjust an elevation angle of the ramp surface, and a mechanically adjustable lift configured to cause the mechanically adjustable ramp insert to descend within the housing as the ramp surface is elevated such that vertical displacement of the user's foot caused by elevation of the ramp surface is substantially attenuated. Related methods are also provided.

A shoe insole and a shoe with an insole structure, which are capable of, concerning the foot arch structure, preventing fallen arches, restoring and correcting the arches, as well as allowing the wearers to maintain the sense of balance. The shoe insole comprises an insole main body having a substantially foot shape; a lower cushioning portion provided on the insole main body in a front portion thereof for supporting a part from the tiptoe to the position of the metatarsal head part; an upper cushioning portion having a substantially U shape provided on the lower cushioning portion for supporting a part corresponding to the positions of the toe, the first toe ball, and the fifth toe ball; and a heel supporting portion provided on the insole main body in a back portion thereof for supporting a portion corresponding to the position of the heel.

A foot has a medial side, a lateral side, a sustentaculum tali, a lateral calcaneus, a fifth metatarsal ray and a forefoot. The support system for a foot comprises of the following. A first portion configured to support an underside portion of the sustentaculum tali at or below the sustentaculum tali on the medial side of the foot to provide a force on the sustentaculum tali. A second portion configured to support the lateral calcaneus on the lateral side of the foot. A third portion configured to support the fifth metatarsal ray on the lateral side of the foot.
