Abstract
A footwear sole comprises an first sole portion including at least one protruding male engagement part and a second sole portion including at least one recessed female engagement part having a shape which closely conforms to that of a corresponding male portion, whereby when a force is applied to the first sole portion in the direction of the second sole portion, the corresponding male engagement part is fixedly retained by the female engagement part. In this manner a shoe-sock may be fixed to the second or another portion of the sole without the need for any adhesive to be used.
