ABSTRACT:
A shoe sole for use in training for improving the muscular strength of the lower extremities when jogging, running or just walking casually, has at least one contractible cavity formed in a heel portion thereof for supporting the heel, and small holes in left and right side walls for communicating with the cavity. The shoe sole promotes walking or running with the wearer's weight positioned forward, and thus, is effective for strengthening the muscles of the lower extremities. Shoes adopting such a shoe sole can be worn safely, since the impact from the ground is alleviated by a cushioning effect according to the contraction of the cavity when the wearer's weight is loaded onto the heel.
