Internal liner for a boot
First Claim
1. A liner for a boot, said liner comprising:
- at least one wedging element;
said wedging element consisting of a thermoplastic foam; and
said wedging element having micro-perforations for increasing flexibility and elasticity of said wedging element, for rendering said wedging element permeable for evacuation of sweat, and for allowing for good and rapid diffusion of heat;
said micro-perforations being through-holes, extending through a thickness of said liner, from a first to a second surface of said liner.

Abstract
A comfort liner provided with a wedging element made of foam having thermoplastic qualities rendering it capable of being adjusted and/or adapted, after being heated at its thermoforming temperature, to the specific volume of the user'"'"'s foot. The liner in its entirety is preformed at an initial fitting volume corresponding to a standard of a given size, and its wedging element, constituted of foam formed from at least one thermoplastic material, is thermocompressed and micro-perforated. The micro-perforations confer to the wedging element a certain flexibility and elastic compressibility, as well as a certain permeability rendering it sufficiently comfortable to be used as such, and adapted to be easily thermoformed by reheating, due to the rapid and in-depth diffusion of the heat across the micro-perforations.
