Insole and its process of manufacturing

Abstract

Process of manufacturing an adhesive insole comprising the steps of: i) providing a support layer which delimits a first surface and an opposite second surface, divided through the thickness (S1) of said layer; ii) adjustably coating a part of the first surface with an adhesion layer, in relief and configured to increase the friction coefficient of the latter; iii) applying at least one adhesive layer to a portion of the second surface; iv) providing a protection substrate comprising a substrate support and at least an overlaid detachment promoting layer; v) combining the products of step iii) and of step iv), so that the detachment promoting layer adheres to the adhesive layer; vi) in the thicknesses (S1, S2) of the support layer and of the substrate support forming an insole contour of the insole. The present invention also relates to an insole not exclusively manufactured with such process.
