Abstract
This envisages making a preliminary form in leather formed by one part 1, determining in its bottom a lower part departing from the heel to act as sole, continuing with a retaining appendix 2 envisaging a system of holes 3, in which, in the moulding stage, the polyurethane material 4 is placed to give rise in the heel body to a retaining system with several vertical parallel retaining elements envisaged at appropriate intervals, to permit balancing of the effect of the deforming stress generated in movement, which stably retains the external part 1 to the part of the polyurethane body associated with it. To make the bottom, it is first envisaged making a preliminary form by punching, composed of parts, 1 and 2 with holes 3. Then a degraining operation is carried out over the top wall of this form, and on the bottom only on the wall of the appendix 2, and then adhesive is spread on said walls subjected to degraining. Then the leather form so made in arranged appropriately for integration into the polyurethane part 4. <IMAGE>
