A heel cushion composed of silicone rubber having a region which can be centrally or eccentrically located directly below the heel spur and composed of a softer silicone rubber than the balance of the heel cushion so that in heel regions subjected to higher pressure, that higher pressure will be absorbed by the softer material and the pressure throughout the back bottom part of the foot will be more uniform.
