ABSTRACT:
Disclosed is an article of footwear such as a shoe having an inner sole and outer sole which delimit a vacant space of a predetermined height between them, the inner sole having a plurality of ventilating holes for communicating the vacant space with the interior of the shoe. A cushion member made of a light-weight, resilient material is disposed within the vacant space at the forward part of the shoe and has a plurality of elongated ribs spaced apart by a predetermined distance and extending to the rear portion of the vacant space. Each elongated rib has at least one recessed portion passing through the rib substantially laterally thereof to communicate with the spaces on either side of the rib. Compression and relaxation of the cushion member with the application and removal of the wearer's weight during walking creates a circulatory air flow to ventilate the interior of the article of footwear.
