ABSTRACT:
A unitary pumping chamber that removes excess heat and moisture from within the footwear to the footwear exterior. The pumping chamber displaces an approximate air volume of 100 cubic centimeters. The placement of the pumping chamber above the midsole but below the foot-enclosing upper allows tension forces generated from flexion of the foot to reinflate the pumping chamber without addition mechanical devices. In addition, the performance of the midsole is not affected because the pumping chamber is not embedded within the midsole.
