Sole structure of a shoe and shoe with such a sole structure

Abstract

The present invention concerns a sole structure ( 10, 110, 910 ) comprising a tread ( 11, 111, 911 ), which comprises at least one portion of breathable material ( 11′, 111′, 911 ′), and a midsole ( 12, 112, 212, 312, 912 ) coupled to said tread ( 11, 111, 911 ), said midsole having:—at least one first channel ( 13, 113, 213, 313, 413, 513, 613, 713, 813 ) having at least one ventilation port ( 14 ) for the fluidic communication with the outside environment, —at least one first through opening ( 15, 115, 215, 315 ) in fluidic communication with said at least one first channel ( 13, 113, 213, 313, 413, 513, 613, 713, 813 ), said sole structure ( 10, 110, 910 ) comprises a waterproof and breathable functional element ( 16, 216, 316 ) which seals said at least one first opening ( 15, 115, 215, 315 ) in a waterproof manner. A shoe ( 20 ) with said sole structure ( 10, 110, 910 ) is further object of the invention.

1 . A sole structure comprising a tread, which comprises at least one portion of breathable material, and a midsole coupled to said tread, said mid sole having:
 at least one first channel having at least one ventilation port for the fluidic communication with the outside environment,   at least one first through opening in fluidic communication with said at least one first channel,   said sole structure being characterized in that it comprises a waterproof and breathable functional element which seals said at least one first opening in a waterproof manner.   
     
     
         2 . The sole structure according to  claim 1 , characterized in that said midsole comprises:
 a first portion which is lower in the configuration for use,   a second portion which is upper in the configuration for use and is joined to said first portion.   
     
     
         3 . The sole structure according to  claim 2 , characterized in that said first portion has said at least one first channel and said second portion has said at least one first opening. 
     
     
         4 . The sole structure according to  claim 2 , characterized in that said first portion of said midsole comprises one or more second openings in fluidic communication with said at least one first channel. 
     
     
         5 . The sole structure according to  claim 2 , characterized in that said first portion of said midsole has one or more first channels delimited by first ribs, said one or more first channels being interrupted by second ribs connecting two successive said first ribs, thus providing blind channels. 
     
     
         6 . The sole structure according to  claim 2 , characterized in that said first portion of said midsole has one or more second channels connecting said one or more first channels. 
     
     
         7 . The sole structure according to  claim 2 , characterized in that said first portion has a cavity in which one or more first channels merge. 
     
     
         8 . The sole structure according to  claim 2 , characterized in that said first portion is made of a three-dimensional fabric. 
     
     
         9 . The sole structure according to  claim 1 , characterized in that said tread comprises a body made of polymeric material. 
     
     
         10 . The sole structure according to  claim 1 , characterized in that it comprises at least one air-filled chamber interposed between said midsole and said at least one portion made of breathable material. 
     
     
         11 . The sole structure according to  claim 1 , characterized in that said midsole is made in one piece with said tread. 
     
     
         12 . The sole structure according to  claim 1 , characterized in that said at least one portion of breathable material is made of leather. 
     
     
         13 . The sole structure according to  claim 2 , characterized in that said functional element is interposed be tween said second portion and said first portion. 
     
     
         14 . The sole structure according to  claim 1 , characterized in that said midsole is made of one or more materials which have:
 a ratio between the elastic and viscous components, determined according to method B of the ASTM D 395-03 standard, of less than approximately 55%,   elastic rebound, determined according to method B of the ASTM D 1054-2000 standard, at least equal to 40%.   
     
     
         15 . A shoe, characterized in that it comprises a sole structure according to  claim 1 .
