ABSTRACT:
This heel device is designed to cause a heel portion of a shoe to rebound when a person walks or jogs. Primarily, it consists of a base plate secured to the bottom of the heel portion of the shoe, and a leaf hinge is secured to the base plate and pivots. Projections are secured to the leaves of the hinge and include a pair of shafts that retain and support an endless rubber belt that provides the tension for the shoe to rebound.
