Sole elements and shoes

Abstract

The present invention relates to a sole element, such as an insole, for a shoe, in particular for a sports shoe, as well as to a shoe, in particular a sports shoe. A sole element for a shoe comprises a first portion and a second portion, wherein the second portion comprises a deformable material, which is adapted to generate heat by being deformed. The sole element moreover comprises a transport element adapted for selectively directing the generated heat from the second portion to the first portion.

What is claimed is: 
     
         1 . A sole element for a shoe, comprising:
 a first portion and a second portion, wherein the second portion comprises a deformable material which is adapted to generate heat by being deformed; and   a transport element adapted for selectively directing the generated heat from the second portion to the first portion.   
     
     
         2 . The sole element according to  claim 1 , wherein a resilience of the deformable material is below 80 percent. 
     
     
         3 . The sole element according to  claim 1 , wherein the first portion comprises a resilient material having a resilience that is higher than a resilience of the deformable material, and/or having a resilience that is at least 20 percent. 
     
     
         4 . The sole element according to  claim 1 , wherein the deformable material comprises a foam material. 
     
     
         5 . The sole element according to  claim 4 , wherein the foam material comprises a (poly-) urethane foam material. 
     
     
         6 . The sole element according to  claim 1 , wherein the sole element is provided as an insole. 
     
     
         7 . The sole element according to  claim 1 , wherein the transport element comprises a heat conductivity of at least 150 mW/(K·m). 
     
     
         8 . The sole element according to  claim 1 , wherein the sole element comprises a first insulating element extending at least partially below the second portion and/or at least partially below the transport element. 
     
     
         9 . The sole element according to  claim 1 , wherein the sole element comprises a second insulating element extending at least partially above the transport element and/or at least partially above the second portion. 
     
     
         10 . The sole element according to  claim 9 , wherein the transport element comprises a forefoot portion above which no insulating element is arranged. 
     
     
         11 . A shoe comprising the sole element according to  claim 1 . 
     
     
         12 . A shoe, comprising:
 a first portion and a second portion, wherein the second portion is arranged at a sole of the shoe and comprises a deformable material which is adapted to generate heat by being deformed; and   a transport element adapted for selectively directing the generated heat from the second portion to the first portion.   
     
     
         13 . The shoe according to  claim 11 , wherein the transport element is at least partly arranged in an upper of the shoe. 
     
     
         14 . The shoe according to  claim 11 , wherein the shoe comprises an insulating layer, at least partly arranged in an outsole and/or a midsole of the shoe. 
     
     
         15 . The shoe according to  claim 14 , wherein the insulating layer is at least partially arranged in at least one recess of the outsole.
