ABSTRACT:
A one-piece heel cushion formed of homogeneous elastomeric material adapted to conform to the insole of a wearer's shoe to relieve the pain of a heel spur. The cushion tapers toward its forward end and has an elongate cavity in the lower surface thereof extending directly under the heel bone, and a slight concavity in the upper surface located over the cavity. The cavity is approximately one-third the height of the cushion at it's rear end resulting in a bridging section over the cavity which flexes under the weight of a person's heel while the portions of the cushion surrounding the cavity bear the major portion of the wearer's weight.
