ABSTRACT:
A resistance device for use with a foot covering comprises an elongated member having a top edge and a bottom edge. An attaching device is disposed on the elongated member. The bottom edge of the elongated member is of greater length than the top edge. Weight receiving chamber structures are disposed on the elongated member in such a position so that weighting material is symmetrically distributed therein about a latitudinal center line of the elongated member. The attaching device is capable of transforming the elongated member into a closed curve of sufficient size to accept an upper portion of a foot covering with the weighting material received in the chamber structures being disposed on lateral and medial sides of the foot covering. The elongated member assumes a generally frusto-conical shape when mounted on the upper portion of the foot covering.
