The part of a boot in question, in particular an inner-boot tongue of a ski boot, is essentially constituted by an outer part (1) made of impermeable semi-rigid plastic having an alveolate structure (6), covered directly by a foam-type padding (4) and by a woven or knitted liner (5). The air contained in the alveoles of the alveolate structure forms a particularly effective damper cushion in dynamic compression.
