Abstract
The bottom or tread layer 18 of a shoe sole 17 is formed with a beaded flange 26 extending outwardly around its upper edge, which serves as a barrieragainst the incursion of the material of the upper sole layer 19 into the side face region 20 of the sole during the casting or moulding of the upper layer. The flange is subsequently removed to leave a clean separation line between the two sole layers.
