First Claim
1. A support system for a foot, the foot having a medial side, a lateral side, a sustentaculum tali, a lateral calcaneus, a heel, a fifth metatarsal ray and a forefoot, an upper portion of the foot being connected to an ankle bone, the support system comprising:
- a generally planar base having a first end proximate the heel of the foot and an opposing second end proximate the forefoot of the foot, a longitudinal axis of the base extending from the first end to the opposing second end;
a first projection extending upwardly from the base, the first projection having a first end and an opposing second end, the first end of the first projection being closer to the first end of the base than the second end of the first projection as measured along the longitudinal axis, the first projection supporting the sustentaculum tali on the medial side of the foot, the first projection providing an upward and outward force on the sustentaculum tali, the first projection not supporting the longitudinal arch;
a second projection extending upwardly from the base, the second projection supporting the lateral calcaneus on the lateral side of the foot; and
a third projection extending upwardly from the base, the third projection having a first end and an opposing second end, the first end of the third projection being closer to the first end of the base than the second end of the third projection as measured along the longitudinal axis, the third projection supporting the fifth metatarsal ray on the lateral side of the foot,wherein the base, the first projection, the second projection and the third projection combine to form a first support,wherein the first and second projections, in combination with the base, define an approximated U-shape with inwardly arching sidewalls,wherein the first projection does not extend upwardly to the ankle bone when the foot is placed on the base and the foot is not rotated, andwherein the second end of the first projection is spaced-apart from the first end of the first end of the third projection as measured along the longitudinal axis.

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.
