ABSTRACT:
In one embodiment, the sole-and-heel structure includes an outer member having a sole portion and a heel portion. A bulge is molded into the heel portion and a bulge is molded into the sole portion in the metatarsal region thereof. A thin sealing member is attached to the outer member with adhesive to hermetically seal the cavities defined by the two bulges. A passageway between the two cavities enables air to move back and forth during movement of a person wearing shoes incorporating such sole-and-heel structure.
