Abstract

The present invention comprises a multilayered heel construction for footwear. A fluid-filled bladder is incorporated into the heel of footwear. The bladder defines an internal cavity which is adapted to enclose a fluid at atmospheric pressure. The internal cavity defines a peripheral channel adjacent the periphery of the bladder and a plurality of intersecting channels orientated transversely to the longitudinal axis of the footwear. The intersecting channels are in communication with the peripheral channel of the interior cavity. The bladder is positioned at the heel of the footwear and is positioned intermediate an upper footbed support. The lower surface of the multilayered heel assembly defines a concave, cantilever surface. The combination of the bladder, the upper footbed support and the lower cantilever surface improve shock absorption and the stability of the footwear.
