Abstract
A shoe sole construction includes a sole member formed from a synthetic plastic material having a first durometer value of hardness and including toe, ball, arch, and heel portions. Relatively rigid toe and heel plates are secured to bottom surface of the sole member on opposite sides of a relatively soft flex bar member that extends transversely across the ball portion of the sole member. A plurality of toe cushion members are mounted for independent movement within openings contained in the toe plate, and a stabilizing arch cushion member is mounted in the recess defined in the heel plate. These cushion members have an intermediate durometer value that, during use, permits compression of these cushion members in a footprint pattern.
