Abstract

A sports boot having an upper, a wear sole and an intermediate sole that has a heel zone with a lateral side, a medial side and a rear side surrounding a central padding. The boot also has a heel bracket with a lateral belt applied against the lateral side, a medial belt applied against the medial side, a rear belt applied against the rear side, a lateral anchoring, a medial anchoring, and retaining arrangement connecting the lateral and medial anchoring at a substantially constant distance one from the other. Furthermore, with the plane of the wear sole as a plane of reference, the elevation of the rear belt is substantially the same as the elevation of the lateral belt and of the medial belt. The retaining arrangement connecting the lateral and medial anchoring can be a strap made from the same material as the heel bracket and integrally formed therewith, or even horizontal tongues that are sandwiched between the intermediate sole and the wear sole at the moment of assembly.

         2 . A sports boot according to  claim 1 , wherein when using the plane of the wear sole as a plane of reference, the elevation of the rear belt is substantially the same as the elevation of the lateral belt and of the medial belt.  
     
     
         3 . A sports boot according to  claim 1 , wherein the retaining arrangement connecting the lateral and medial anchoring have a strap made of the same material as the heel bracket and integrally formed therewith.  
     
     
         4 . A sports boot according to  claim 1 , wherein the intermediate sole has a first shock-absorbing material on which a second shock-absorbing material is affixed that is more flexible than said first material.  
     
     
         5 . A sports boot according to  claim 4 , wherein in the heel zone of the sole, the first shock-absorbing material defines a cavity, the second material having a complementary shape thereto.  
     
     
         6 . A sports boot according to  claim 1 , wherein in its front portion, the intermediate sole has shock-absorbing arrangement constituted by a plurality of upper protuberances and a plurality of lower protuberances.  
     
     
         7 . A sports boot according to  claim 1 , wherein the intermediate sole has a lower half-sole and an upper half-sole made from a material that is more flexible than the material of the lower half-sole.  
     
     
         8 . A sports boot according to  claim 5 , wherein the lower protuberances as well as the cavity are provided on the lower half-sole.  
     
     
         9 . A sports boot according to  claim 1 , wherein the retaining arrangement connecting the lateral and medial anchoring are constituted by horizontal tongues sandwiched between the intermediate sole and the wear sole when the sole is assembled.  
     
     
         10 . A sports boot according to  claim 1 , wherein the heel bracket has a lower portion connected to the medial and lateral belts by means of a medial and lateral leg, respectively.
