Sole and shoe

Abstract

Described are soles for a shoe, in particular for a sports shoe, with a midsole. The midsole includes a first sole region, which includes particle foam. The midsole further includes a deformation region within the midsole, wherein the deformation region has a volume greater than that of a single expanded particle and is positioned so that it allows a sideward deformation of the material of the first sole region under a pressure load on the sole.

         8 . The sole according to  claim 4 , wherein the control element is free from particles of the particle foam. 
     
     
         9 . The sole according to  claim 1 , wherein the deformation region comprises a material that yields to the deformation of the material of the first sole region. 
     
     
         10 . The sole according to  claim 9 , wherein the yielding material has a deformation stiffness that is 5%-40% greater than the deformation stiffness of the first sole region.

         12 . The sole according to  claim 1 , further comprising:
 a second sole region comprising particle foam and providing an increasing deformation stiffness along at least one predetermined direction.   
     
     
         13 . The sole according to  claim 12 , wherein the increase in the deformation stiffness is at least partially due to an increase in density of the particle foam of the second sole region along the at least one predetermined direction. 
     
     
         14 . The sole according to  claim 12 , wherein the at least one predetermined direction extends from a medial side of the sole towards a lateral side of the sole. 
     
     
         15 . The sole according to  claim 12 , wherein the increase in deformation stiffness in the second sole region is smaller in an area where impact occurs and larger on an opposite side of the second sole region. 
     
     
         16 . The sole according to  claim 15 , wherein at least the second sole region tilts inwards toward the impact area due to a stronger compression of the second sole region in the impact area. 
     
     
         17 . The sole according to  claim 1 , wherein at least one of a shape, size, and location of the deformation region configures the deformation region to a desired output. 
     
     
         18 . The sole according to  claim 12 , wherein the first sole region extends into a forefoot region and wherein the second sole region extends into a heel region. 
     
     
         19 . The sole according to  claim 12 , wherein the first sole region and the second sole region at least partially coincide. 
     
     
         20 . A sole comprising:
 a midsole comprising a first sole region, wherein the first sole region comprises particle foam;   a deformation region within the midsole, wherein the deformation region comprises a volume greater than that of a single expanded particle and is positioned so that it allows a sideward deformation of the particle foam of the first sole region under a pressure load on the sole; and   a frame element, which at least partially surrounds the midsole and which limits the sideward deformation of the midsole under the pressure load on the sole.   
     
     
         21 . The sole according to  claim 20 , wherein the frame element completely encompasses a heel region on its sides, and wherein the frame element only partly encompasses a forefoot region on its sides. 
     
     
         22 . The sole according to  claim 20 , wherein the frame element further comprises a supporting element, wherein the supporting element is arranged on the lateral side of a heel region. 
     
     
         23 . The sole according to  claim 20 , wherein the midsole further comprises a control element that limits the sideward deformation of the particle foam of the first sole region.
