Abstract: 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.

Abstract: A foot has a medial side, a lateral side, a sustentaculum tali, a lateral calcaneus, a fifth metatarsal ray, a forefoot and an anatomical midline. A shoe last comprises an upper and a sole unit of a shoe for a foot are assembled. The last comprises a form defining a foot compartment for orienting a foot. A shoe formed around the form has a support includes the following. A first portion configured to support the sustentaculum tali on the medial side of the foot for providing an upward and outward force on the 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.

Abstract: 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 a base. A first projection configured to support the sustentaculum tali on the medial side and, in use, to provide a force on the sustentaculum tali. A second projection configured to support the lateral calcaneus on the lateral side of the foot. A third projection configured to support the fifth metatarsal ray on the lateral side of the foot. The first, second and third projections extend, in use, upwardly from the base, and the first and second projections define an approximated U-shape with inwardly arching sidewalls.

Abstract: A shoe comprising: an assembly of a shoe upper and sole unit for supporting a foot, the assembly defining a foot compartment that orients a foot in an objective (desired) tri-planar alignment to affect three areas of the foot anatomy simultaneously: (1) the sustentaculum tali; (2) the lateral calcaneus; and (3) the fifth metatarsal ray of the foot. In certain embodiments the shoe compartment is configured to correct an adverse internal rotation of the talus by: (1) vertical lift on the ST; (2) varus movement of the calcaneus; and (3) fifth ray pressure to adduct the forefoot.
