ABSTRACT:
The sole comprises a case in which a liquid-containing chamber is connected to an air-containing chamber by means of a resilient inner wall. Pressure on the weight-bearing portion of the foot is redistributed isostatically across the plantar portion of the foot by the liquid-containing chamber. The pressure created in the liquid-containing chamber is applied against the air chamber. The compressed air chamber and inner wall which presses against it store energy when the foot pushes against the ground and release it, spring-like, into the liquid chamber when the foot moves from the ground. The sole also provides for use of unequal ceiling and floor surface areas in the liquid chamber for decreased or increased forces felt on the foot.
