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.
