ABSTRACT:
The sole comprises a case in which a liquid-containing chamber is connected to a chamber containing sponge-like material. Pressure on the weight-bearing portion of the foot is redistributed isostatically by the liquid-containing chamber. The pressure created in the liquid-containing chamber is applied against chamber having the air-containing material. The compressed air-material chamber stores energy when the foot pushes against the ground and releases 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.
