<p>A climbing shoe (1) having an upper (2) of appropriate shape; an innersole (3) fixed to the bottom (2a) of the upper (2) to cover at least the portion of the upper (2) corresponding to the metatarsal-phalangeal area (P 1 ) of the sole of the foot; a sole (4) fixed to the bottom (2a) of the upper (2) to cover the whole innersole (3); and a number of tensioning bands (5, 6, 7, 8) of elastic material, fixed to the upper (2) to surround and evenly grip the user's foot; the innersole (3) being defined by a plastic or composite material strip (3) which is substantially rigid in response to mechanical stress parallel to the plane of the strip, and flexible in response to stress perpendicular to the plane of the strip; the tensioning bands (5, 6, 7, 8) including a substantially V-shaped first tensioning band (5), which has the central portion (5') glued directly to the innersole (3) to cover the area of the upper (2) corresponding to the metatarsal-phalangeal area (P 1 ), and has the two lateral portions (5") that extend along the two sides (2b) of the upper (2), roughly up to the point where the astragalus joins the calcaneus of the foot; said lateral portions (5") of the first tensioning band (5) being glued directly to the upper (2).</p> |
