Air-ventilated shoe sole

Abstract

A mid-sole body has air inlet openings in the heel section and air outlet openings in the midfoot section and/or ball/toe section. The air inlet openings are connected to the air outlet openings via a ventilation channel. The ventilation channel is covered by a cover which is elastically resilient in the direction of the outsole during walking when under strain. The shoe is force-ventilated due to the rolling off of the shoe having such a shoe sole during walking and heat is removed from the shoe sole.

         14 . A shoe sole with a midsole, having a midsole body extending over a heel region, a midfoot region and a ball/toe region, and with an outsole, wherein the midsole body has at least one air inlet opening in the heel region, air outlet openings in the midfoot region and/or the ball/toe region, and also a ventilation channel, which connects the air inlet opening to the air outlet openings and is covered on the side facing away from the outsole by means of a cover, which is elastically compliant, in the direction of the outsole, when under load during walking. 
     
     
         15 . The shoe sole as claimed in  claim 14 , wherein, in a rear portion, seen in the walking direction, of the heel region there is a respective air inlet opening both on the outer side and on the inner side, and in the midfoot region and/or the ball/toe region there are air outlet openings both on the outer side and on the inner side. 
     
     
         16 . The shoe sole as claimed in  claim 15 , wherein the ventilation channel has in the heel region a V-shaped heel portion, leading with its legs to the air inlet openings, and in the midfoot region and possibly the ball/toe region has a distributor portion, which adjoins the heel portion and has a central main channel portion and branch channel portions, branching off laterally from the latter and leading to the air outlet openings. 
     
     
         17 . The shoe sole as claimed in  claim 14 , wherein the ventilation channel has two main channel portions, running at least approximately in the longitudinal direction of the shoe sole and connected to the air inlet openings, branch channel portions branching off from one of the main channel portions to the outer air outlet openings and from the other of the main channel portions to the inner air outlet openings. 
     
     
         18 . The shoe sole as claimed in  claim 14 , wherein the cover has an insole, which has a carrier layer and, on the side of the carrier layer that is facing the midsole body, an elastically compliant supporting layer. 
     
     
         19 . The shoe sole as claimed in  claim 18 , wherein the supporting layer has a multiplicity of supporting elements arranged at a distance from one another, protruding from the carrier layer and supported on the midsole. 
     
     
         20 . The shoe sole as claimed in  claim 18 , wherein the supporting layer has a multiplicity of wave-shaped supporting strips, protruding from the carrier layer and supported on the midsole. 
     
     
         21 . The shoe sole as claimed in  claim 18 , wherein the supporting layer has a knitted spacer fabric, which is supported on the midsole. 
     
     
         22 . The shoe sole as claimed in  claim 14 , wherein a soft heel part is arranged in a heel recess of the midsole body, the outsole, in the unloaded state, is kept in a form in which it is rounded in a convex manner in the longitudinal direction of the shoe sole by the midsole body and the soft heel part, and the midsole has in the heel region and in the midfoot region a reinforcing element with such a stability that the midsole is at least approximately flexurally rigid, with respect to loads during standing and walking, in its portion located above the soft heel part. 
     
     
         23 . The shoe sole as claimed in  claim 22 , wherein the reinforcing element is integrated in the midsole body and has a channel-like recess for the ventilation channel. 
     
     
         24 . The shoe sole as claimed in  claim 17 , wherein, in the transverse direction of the shoe sole, the reinforcing element in the midsole body is arranged in a central region and one of the main channel portions runs on each side of the reinforcing element. 
     
     
         25 . The shoe sole as claimed in  claim 24 , wherein a ventilation insert element, which is preferably U-shaped in plan view, is integrated in the midsole body, delimits the main channel portions with a cross-sectionally U-shaped channel wall and has air inlet tube stubs, which protrude from the channel wall in the heel region and are flow-connected to the main channel portions, and air outlet tube stubs, which protrude from the channel wall in the midfoot region and/or the ball/toe region and are flow-connected to the main channel portions. 
     
     
         26 . A walking device with a shoe sole as claimed in  claim 14  and an upper arranged on the shoe sole.
