Definitions

  • the present invention relates to a climbing shoe.
  • most climbing shoes is usually made up of an leather shoe-upper which is substantially sock-shaped so as to enclose and completely cover the foot, including the sole of the foot; of a front tensioning band which is substantially U-bent and is fixed by gluing to the tip of the shoe-upper so as to surround the tarsus-phalangeal region of the sole of the foot; of a rear tensioning band which is substantially U-bent and is fixed by gluing to the rear part of the shoe-upper so as to cover the area above the heel of the foot, and then extend along the two lateral sides of the shoe-upper up to reach and join with the front tensioning band; and of a vulcanised-rubber sole which is fixed by gluing to the bottom of the shoe-upper, over the front and rear tensioning bands, so as to cover the whole sole of the foot.
  • the front and rear tensioning bands are made of highly elastic rubber and are suitably pre-tensioned so as to embrace and tighten the user's foot to the limit of physical pain, generally also arching the foot downwards.
  • US patent application US2003/196354 describes a climbing shoe having, in the heel area, a series of transversal protruding ridges that allow the user to grip on rocks and similar footholds, and EP1880622A1 discloses a shoe according to the preamble of claim 1.
  • Aim of the present invention is therefore to realize a climbing shoe free from the drawbacks described above.
  • number 1 denotes as a whole a climbing shoe that may be particularly advantageously used for climbing in indoor climbing walls.
  • the climbing shoe 1 basically comprises: a shoe-upper 2 preferably made of leather, which is shaped substantially like a sock so as to completely cover the user's foot, including the sole of the foot; and a front sole 3 made of high-grip vulcanised rubber or other similar soft elastomeric material (such as, for example, the XS Edge compound or the GRIP 2 compound produced by VIBRAM), which is firmly fixed, preferably by gluing, to the bottom or insole 4 of the shoe-upper 2, and is shaped/structured so as to cover the portion of the bottom 4 of shoe-upper 2 which is located below the tarsus-phalangeal region 4a of the user's foot, more or less up to the boundary with the plantar-arch region 4b.
  • a shoe-upper 2 preferably made of leather, which is shaped substantially like a sock so as to completely cover the user's foot, including the sole of the foot

  • the two ends 6a of rear tensioning band 6 moreover are joined/connected, preferably by gluing, to each other and/or with the two ends 5a of front tensioning band 5 on the bottom 4 of shoe-upper 2, substantially in the area of the plantar-arch region 4b.
  • the two ends 6a of rear tensioning band 6 preferably extend on the bottom 4 of shoe-upper 2, in the plantar-arch region 4b and optionally also in the tarsus-phalangeal region 4a and/or in the talus-calcaneal region 4c of the sole of the foot, so as to cover the portion of the bottom 4 of shoe-upper 2 which is located immediately beneath the plantar-arch region 4b and optionally also beneath a small part of the tarsus-phalangeal region 4a and/or a small part of the talus-calcaneal region 4c.
  • the two ends 6a of rear tensioning band 6 are preferably dimensioned so as to substantially completely cover the portion of the bottom 4 of shoe-upper 2 which is below the plantar-arch region 4b, optionally also with the addition of a small sector of the bottom 4 of shoe-upper 2 beneath the tarsus-phalangeal region 4a of the sole of the foot.
  • the two ends 5a of front tensioning band 5 extend on the bottom 4 of shoe-upper 2 so as to cross the borderline between the tarsus-phalangeal region 4a and the plantar-arch region 4b, at least partially covering the plantar-arch region 4b while locally overlapping the two ends 6a of rear tensioning band 6.
  • the climbing shoe 1 is furthermore provided with a protective insert 10 made of rubber or other elastomeric material, which is substantially seashell-shaped and is fixed, preferably by gluing, directly on the rear part 8 of shoe-upper 2, in the area delimited at the top by the rear tensioning band 6, so as to cover the portion of shoe-upper 2 located in the heel area.

  • the protective insert 10 is moreover shaped /dimensioned so as to extend on the bottom 4 of shoe-upper 2 up to reach the plantar-arch region 4b, thus to reach/join with the two ends 6a of tensioning band 6.
  • the protective insert 10 is preferably shaped/dimensioned so as to cover substantially the entire portion of the bottom 4 of shoe-upper 2 located beneath the talus-calcaneal region 4c of the sole of the foot, and to additionally extend on the portion of the bottom 4 located beneath the plantar-arch region 4b, underneath the two ends 6a of rear tensioning band 6.
  • the climbing shoe 1 furthermore comprises a rear sole 11 made of high-grip vulcanised rubber or other similar soft and flexible elastomeric material (such as, for example, the XS Edge compound or the GRIP 2 compound produced by VIBRAM), which is firmly fixed to the bottom or insole 4 of shoe-upper 2 in the heel area preferably by gluing, and is shaped/dimensioned so as to at least partially cover the portion of the bottom 4 of shoe-upper 2 located beneath the talus-calcaneal region 4c of the sole of the foot, and also the rear part 8 of the shoe-upper 2 at the heel area, preferably up to the rear tensioning band 6.
  • a rear sole 11 made of high-grip vulcanised rubber or other similar soft and flexible elastomeric material (such as, for example, the XS Edge compound or the GRIP 2 compound produced by VIBRAM), which is firmly fixed to the bottom or insole 4 of shoe-upper 2 in the heel area preferably by gluing, and is shaped/dimensioned so
  • the rear sole 11 is preferably shaped /dimensioned so as to cover the portion of the bottom 4 of shoe-upper 2 located beneath the talus-calcaneal region 4c of the sole of the foot, approximately up to the border with the plantar-arch region 4b, additionally locally overlapping the protective insert 10 if present.
  • the rear sole 11 is thus separated and spaced from the front sole 3.
  • the rear sole 11 moreover includes at least one transversal protruding ridge or rib 12, which extends over the rear part 8 of shoe-upper 2, straddling and substantially perpendicular to the midplane of the shoe, i.e. locally substantially parallel to the bottom or insole 4 of the shoe-upper 2; and a reinforcing core 13 that extends into the protruding ridge 12, preferably substantially for the whole length of the transversal protruding ridge 12, and is made of a material which is more rigid than the elastomeric material forming the exterior of the transversal protruding ridge 12, so as to locally stiffen the protruding ridge 12.
  • transversal protruding ridge or rib 12 is preferably located on the rear part 8 of shoe-upper 2, straddling the midplane of the shoe, substantially at the point where the Achilles tendon is attached to the calcaneus.
  • the protruding ridge or rib 12 is moreover externally made of a high-grip vulcanised rubber or other similar soft and flexible elastomeric material (such as, for example, the XS Edge compound or the GRIP 2 compound produced by VIBRAM) like the rest of the rear sole 11.
  • a high-grip vulcanised rubber or other similar soft and flexible elastomeric material such as, for example, the XS Edge compound or the GRIP 2 compound produced by VIBRAM
  • the reinforcing core 13 is preferably made of a polymeric material, preferably of an elastomeric type, having density and/or hardness greater than that of the elastomeric material forming the rest of rear sole 11 and protruding ridge 12, and preferably via injection moulding.
  • the material forming the outer part of protruding ridge or rib 12 has a density (UNI 7092) preferably ranging between 1.15 and 1.19 g/cm3 (grams per cubic centimetre), and a hardness (UNI 4916) preferably ranging between 69 and 73 Shore A.
  • the rear sole 11 is also injection moulded directly over and onto the reinforcing core 13.
  • the transversal protruding ridge 12 preferably has a cross-section substantially semicircular or trapezoidal in shape, and a height preferably ranging between 5 and 15 mm (millimetres).
  • the reinforcing core 13 in turn, preferably has a monolithic profile with a substantially semicircular or trapezoidal cross-section.
  • the reinforcing core 13 is furthermore made of ethylene-vinyl acetate (EVA) or of thermoplastic polyurethane (TPU), preferably via an injection moulding process.
  • EVA ethylene-vinyl acetate
  • TPU thermoplastic polyurethane
  • the climbing shoe 1 preferably additionally includes a substantially ribbon-like medial tensioning band 14 which is firmly fixed to the bottom or insole 4 of shoe-upper 2 preferably by gluing, and extends on the area of bottom 4 covered by the front sole 3 up to the area of bottom 4 covered by the rear sole 11 while remaining more or less straddling the midplane of the bottom 4.
  • a substantially ribbon-like medial tensioning band 14 which is firmly fixed to the bottom or insole 4 of shoe-upper 2 preferably by gluing, and extends on the area of bottom 4 covered by the front sole 3 up to the area of bottom 4 covered by the rear sole 11 while remaining more or less straddling the midplane of the bottom 4.
  • the medial tensioning band 14, therefore, connects the front sole 3 to the rear sole 11 and is adapted to prevent the stretching of the shoe-upper 2.
  • the medial tensioning band 14 is preferably made of a high-elasticity rubber or other similar elastomeric material, and is preferably pre-tensioned.
  • the medial tensioning band 14 moreover has a width preferably always less than the width of the bottom 4 of shoe-upper 2, and extends along the bottom 4 of shoe-upper 2, from the portion beneath the tarsus-phalangeal region 4a of the sole of the foot up to the portion beneath the talus-calcaneal region 4c, preferably overlapping the two ends 5a of front tensioning band 5 and the two ends 6a of the rear tensioning band 6.
  • the presence of the reinforcing core 13 prevents the protruding ridge or rib 12 of rear sole 11 from deforming under heavy tangential loads, thus allowing the user to grip with the heel on any rock or other foothold without any risk of sudden failure.
  • the rear sole 11 is made in one piece with the front sole 3 so as to form a large monolithic sole of high-grip vulcanized rubber or other similar soft and flexible elastomeric material, which is firmly fixed to the bottom or insole 4 of shoe-upper 2, preferably by gluing, to cover the whole bottom 4, and moreover extends also along the rear part 8 of shoe-upper 2 preferably up to the rear tensioning band 6.
  • transversal protruding ridge or rib 12 is thus incorporated into the large monolithic sole, approximately at the point where the Achilles tendon is attached to the calcaneus, together with the reinforcing core 13.
  • the climbing shoe 1 lacks the medial tensioning band 14.
