Climbing shoe

Abstract

A climbing shoe comprising a substantially sock-shaped shoe-upper, so as to completely cover the foot of the user; a front sole which is fixed on the bottom part of the shoe-upper so as to cover the tarsal-phalangeal region of the sole of the foot; a rear sole which is discrete and spaced apart from the front sole and is fixed on the bottom part of the shoe-upper so as to at least partly cover the talus-calcaneus region of the sole of the foot; and a substantially ribbon-shaped, medial tensioning strip which is made of inextensible material and is fixed on the bottom part of the shoe-upper so as to extend substantially along the center line of the sole of the foot, from the area of the shoe-upper under the front sole up to the area of the shoe-upper under the rear sole following an arched trajectory.

         4 . The climbing shoe according to  claim 1 , characterized in that the medial tensioning strip has a width which is always less than the width of the bottom part of the shoe upper. 
     
     
         5 . The climbing shoe according to  claim 1 , characterized in that the medial tensioning strip is made of a plastic or composite material of inextensible type. 
     
     
         6 . The climbing shoe according to  claim 5 , characterized in that the medial tensioning strip is made of extruded polypropylene or of NYLON or of PEBAX or of FLEXAN PLUS. 
     
     
         7 . The climbing shoe according to  claim 1 , characterized by also comprising a front tensioning strip which is made of elastic material, is fixed on the toe of the shoe-upper, and is substantially U-shaped so as to cover the toe of the shoe-upper in the area surrounding the tarsal-phalangeal region of the sole of the foot. 
     
     
         8 . The climbing shoe according to  claim 7 , characterized in that the front tensioning strip additionally extends partly over the bottom part of the shoe-upper, underneath the front sole. 
     
     
         9 . The climbing shoe according to  claim 7 , characterized in that the two ends of the front tensioning strip are provided with longitudinal appendages which extend/prolong along the bottom part of the shoe-upper upper, so as to reach and at least partly cover the insole arch region while joining each other. 
     
     
         10 . The climbing shoe according to  claim 9 , characterized in that the medial tensioning strip extends along the bottom part of the shoe-upper, from the tarsal-phalangeal region of the sole of the foot to the talus-calcaneus region, passing over the longitudinal appendages of the front tensioning strip. 
     
     
         11 . The climbing shoe according to  claim 1 , characterized by also comprising a rear tensioning strip which is made of elastic material, is fixed on the rear part of the shoe-upper, and is substantially U-shaped so as to cover the rear part of the shoe-upper in the area immediately over the heel and then extend/prolong along the two lateral sides of the shoe-upper. 
     
     
         12 . The climbing shoe according to  claim 11 , characterized in that the rear tensioning strip extends along the two lateral sides of the shoe-upper up to reach and join the two ends of the front tensioning strip. 
     
     
         13 . The climbing shoe according to  claim 11 , characterized in that the two ends of the rear tensioning strip additionally extend on the bottom part of the shoe-upper, along the insole arch region, so as to at least partly cover the insole arch region. 
     
     
         14 . The climbing shoe according to  claim 13 , characterized in that the longitudinal appendages of the front tensioning strip join the ends of the rear tensioning strip at the insole arch region. 
     
     
         15 . The climbing shoe according to  claim 13 , characterized in that the medial tensioning strip extends along the bottom part of the shoe-upper, from the tarsal-phalangeal region of the sole of the foot to the talus-calcaneus region, while passing over the ends of the rear tensioning strip. 
     
     
         16 . The climbing shoe according to  claim 10 , characterized in that the medial tensioning strip is glued over the longitudinal appendages of the front tensioning strip and/or the ends of the rear tensioning strip. 
     
     
         17 . The climbing shoe according to  claim 1 , characterized in that the rear sole is shaped/designed so as to also extend on the rear part of the shoe-upper, so as to cover and protect the back of the calcaneum of the foot.
