Abstract

A forced-air footwear is presented and comprises a foot supporting portion including a sole with cavities therein covered with a foot-contacting layer, and a channel communicating between the cavities and the interior of the footwear to allow air flow between the cavities and the interior of the footwear; a foot covering portion, the foot covering portion including a valve allowing air passage therethrough in a single direction, the cavities including a compressed configuration, when supporting a weight of a wearer, and an expanded configuration when not supporting the weight of a wearer, the passage between the compressed configuration and the expanded configuration forcing an air movement of the air contained in the cavities, the valve blocking the air movement in one direction, wherein the compression of the cavities and the blocking action of the air by the valve is forcing air through the footwear.
