MANUFACTURE AND FINISHING

In order to create a double density sole, the outer skin is created by firstly injecting the polyurethane into the mould. The upper is then positioned above it and the mould closed. A polyurethane compound of a lighter density is then injected between the upper and the outer sole, bonding the two components together in the process. The inner sole provides additional comfort and shock absorption.

During this process, pre-programmed robots perform important functions such as applying a release agent to the mould, and roughening the Upper for good bonding.
