Method and mould for manufacturing a wear sole of a shoe, by vulcanization, in at least two substantially horizontal layers of different colours - sole thus obtained

摘要

The shoe includes a wear sole 2 fastened to the upper 1 by means of a midsole 3, this sole 2 having, in its rising part 7, at least two substantially horizontal layers 4, 5 of different colours. According to the invention, the wear sole 2 has, projecting, on the one hand, an upper lip 14 on the underlying layer 4, in order to ensure leaktightness upon injection between the latter and the midsole 3, and, on the other hand, an intermediate lip 15 extending the interface I of the two layers 4, 5, in order to ensure leaktightness upon final vulcanization between the latter.
