Shoe structure

Abstract

A shoe structure includes an upper assembly, having an upper and an insole, a bottom, joined in a lower region to the upper assembly and including a sole and a midsole, the sole having a tread. The sole includes one or more tabs monolithic therewith, directed toward the midsole.

1 . A shoe structure comprising:
 an upper assembly, comprising an upper and an insole,   a bottom, joined in a lower region to said upper assembly and comprising a sole and a midsole, said sole comprising a tread,   wherein said sole comprises one or more tabs monolithic therewith, directed toward said midsole.   
     
     
         2 . The shoe structure according to  claim 1 , wherein said sole comprises one or more crossmembers that are monolithic therewith. 
     
     
         3 . The shoe structure according to  claim 1 , wherein said sole comprises a lateral element and each one of said one or more tabs is joined to the internal side wall of said lateral element by a first crossmember. 
     
     
         4 . The shoe structure according to  claim 1 , wherein two successive ones of said tabs are connected by a second crossmember. 
     
     
         5 . The shoe structure according to  claim 1 , wherein said lateral element comprises one or more windows. 
     
     
         6 . The shoe structure according to  claim 1 , wherein said insole is joined to the lower edges of said upper by means of a stitched seam. 
     
     
         7 . The shoe structure according to  claim 1 , wherein said insole comprises a first layer made of three-dimensional fabric. 
     
     
         8 . The shoe structure according to  claim 1 , wherein said insole comprises a second layer, the extension of said second layer being comprised between approximately one third and approximately half of the contact surface of said insole with a foot of a user. 
     
     
         9 . The shoe structure according to  claim 1 , wherein in said midsole there are:
 one or more through holes,   and/or one or more blind holes, which extend over only part of the thickness of said midsole and lead out toward said tread.   
     
     
         10 . The shoe structure according to  claim 1 , wherein said one or more through holes have a portion with constant cross-section. 
     
     
         11 . The shoe structure according to  claim 1 , wherein a part of said one or more through holes has a portion with reduced cross-section that is formed proximally to the upper surface of said midsole. 
     
     
         12 . The shoe structure according to  claim 1 , wherein said one or more through holes are arranged at a front portion of said midsole and/or at an internal middle portion of said midsole. 
     
     
         13 . The shoe structure according to  claim 1 , wherein said one or more through holes are arranged at a tip portion of said midsole and/or at an internal central portion of said midsole. 
     
     
         14 . The shoe structure according to  claim 1 , wherein said one or more blind holes are arranged at a rear portion of said midsole and/or at an external middle portion of said midsole. 
     
     
         15 . The shoe structure according to  claim 1 , wherein said one or more blind holes are arranged at a complementary portion of said midsole that is substantially complementary to said tip portion and/or to said internal central portion. 
     
     
         16 . The shoe structure according to  claim 1 , wherein said bottom comprises one or more ducts, said ducts mutually connecting:
 one or more of said through holes,   and/or one or more of said blind holes,   and/or one or more of said through holes to one or more of said blind holes.   
     
     
         17 . The shoe structure according to  claim 1 , wherein a part of said ducts has an extension along a predominant direction of extension ( 19 ) that is oriented substantially from the resting region of the lateral side of said foot toward the resting region of the medial side of said foot. 
     
     
         18 . The shoe structure according to  claim 1 , wherein said sole is made of a material with a hardness comprised between approximately 60 and approximately 90 Shore A and/or a density comprised between approximately 0.9 and approximately 1.3 g/cm 3 . 
     
     
         19 . The shoe structure according to  claim 1 , wherein said midsole is made of a material with a hardness comprised between approximately 30 and approximately 80 Asker C and/or a density comprised between approximately 0.2 and approximately 0.6 g/cm 3 .
