ABSTRACT:
A shoe sole and heel construction is provided. The construction includes a structure having an exterior ground-contacting surface, a flexible bulge formed in the structure and projecting from the exterior ground-contacting surface for contact with the ground in use and defining a first pocket. The construction also includes a second resiliently expansible pocket formed in the structure and disposed to avoid contact with the ground in use and a passageway formed in the structure and communicating with each of the first and second pockets. Fluid is permanently confined in a space jointly defined by the pockets and the passageway whereby when an external force is applied to the bulge, fluid is forced from the first pocket through the passageway to expand the second pocket and when the external force is removed, the expanded second pocket resiliently forces fluid back to the first pocket.
