Abstract
Method for the manufacture of a relief profiled outer sole of cross-linked EVA polymer foamed with closed cells is described in which the polymer used is formed into a cross-linked, expanded tempered blank, split by at least one cut into several subblanks, and whereupon the surface of a subblank is heated and pressed to form the relief profile. The temperature gradient of the blank while it is being pressed is important for precise formation of the relief profile.
