An energy-return shoe system includes a shoe portion having a sole. The sole has a toe area and a heel area. The sole is capable of bending at a point between the toe area and the heel area. A lower sole has a toe area and a heel area and is bendable at a point between the toe area and the heel area. A heel mechanism interfaces the shoe heel area to the lower sole heel area and holds the shoe heel sole area in horizontal synchronization with the lower heel sole area thereby maintaining a same horizontal position between the heel areas and allowing front and rear ends of the heel areas to close and open at the same rate. A spring or other device pushes the heel areas away from each other, thereby absorbing energy upon impact and releasing the energy on step-off. |
