Definitions

  • the present invention relates to a climbing shoe.
  • climbing shoes generally comprise: a leather shoe-upper which is substantially sock-shaped so as to accommodate and completely cover the foot, including the sole of the foot; a front tensioning band made of highly elastic rubber, which is substantially U-bent and is fixed by gluing onto the tip of the shoe-upper so as to surround the tarsus-phalangeal region of the foot; a rear tensioning band made of highly elastic rubber, which is substantially U-bent and is fixed by gluing to the rear part of the shoe-upper so as to cover the region above the calcaneus of the foot, and then extends along the two lateral sides of the shoe-upper up to meet and join to the front tensioning band; and a sole made of soft, flexible and substantially non-extendible elastomeric material with high friction coefficient, which is fixed by gluing to the bottom of the shoe-upper, above the front and rear tensioning bands, so as to cover the whole sole of the user's foot.
  • the sole is moreover provided at the back with a large oblong tongue that rises along the heel up to the height of the rear tensioning band while remaining substantially astride the midplane of the shoe, and in addition overlaps two protective inserts made of low-elasticity rubber or other similar elastomeric material, which are substantially seashell-shaped and are fixed by gluing onto the two lateral sides of the shoe-upper so as to cover and protect both sides of the calcaneus of the user's foot.
  • Aim of the present invention is therefore to provide a climbing shoe that overcomes the drawbacks described above.
  • a climbing shoe as defined in claim 1 and preferably, though not necessarily, in any one of the dependent claims.
  • reference numeral 1 denotes as a whole a climbing shoe that may be particularly advantageously used for climbing on rock walls classified as grade IV or lower, where climbers may have to use the heel of their foot for climbing.
  • the climbing shoe 1 firstly comprises: a shoe-upper 2, preferably made of leather, which is substantially sock-shaped so as to accommodate and completely cover the foot of the user, including the sole of the foot; and a front sole 3 made of a soft, flexible and substantially non-extendible elastomeric material with a high friction coefficient, which is firmly fixed to the bottom or insole 4 of shoe-upper 2 preferably by gluing.
