a base, the first, second and third portions being first, second and third projections attached to the base, the first, second and third projections extend, in use, upwardly from the base, the first and second projections defining an approximated U-shape with inwardly arching sidewalls, the first projection of the first support having an interior surface and an exterior surface;

a second support removably coupled to the first support, the second support having:

a first portion, in use and in combination with the first portion of the first support, providing a force to an underside portion of the sustentaculum tali on the medial side of the foot to provide an upward and outward force on the sustentaculum tali; and

a base, wherein the first portion of the second support is a first projection, the first projection of the second support having an interior surface and an exterior surface, the interior surface of the first projection of the first support being coupled to the exterior surface of the first projection of the second support;

a shoe upper coupled to at least one of the first and second supports.

11. The support system of claim 10 , further comprising a first fastener on the interior surface of the first projection of the first support and a second fastener on the exterior surface of the first projection of the second support removably coupling the second support to the first support.

12. The support system of claim 11 , wherein the shoe upper has a medial side and a lateral side, and further includes a hole disposed on the medial side of the shoe upper.

13. The support system of claim 12 , wherein the first fastener is engages the second fastener through the hole in the shoe upper.

14. The support system of claim 13 , wherein the first and second fasteners are corresponding hook and loop fasteners.

15. The support system of claim 11 , wherein the shoe upper has a medial side and a lateral side, and further includes an adjustable fastener disposed on the medial side of the shoe upper and connectable to the first support for adjusting the fit of the support system.

16. The support system of claim 1 , wherein the first projection extends upwardly from the base less than three inches when the foot is placed on the base and the foot is not rotated.

17. The support system of claim 1 , further comprising at least one convex groove or ridge on an exterior surface of at least a portion of the support system, the at least one groove or ridge providing directional and functional stiffness and reinforcement.

18. The support system of claim 1 , wherein at least a portion of the second end of the base extends in a straight line.

19. 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:
