Abstract

A procedure for the manufacture of footwear, essentially characterized by the fact that, after mounting on the last of the lining, instep and sole, it is not necessary to exert a particular compression to ensure the perfect adhesion of these parts to the last with elimination of the interposed air, a depression is made inside the last itself that proceeds to the elimination of any vestige of air interposed between the parts of the boot placed on the last and between it and the last itself, after which the last on which the boot is mounted is introduced into the vulcanization autoclave without having to exert a depression inside the last during its stay in the autoclave.
