Midsole for a sports shoe with banking effect

Abstract

Midsoles for a sports shoe that comprise a ground facing component comprising a rim portion with a first inward-facing wedge-shaped elongate protrusion and a foot support component arranged slidably at least partially inside the ground facing component. The foot support component may comprise a first outward facing wedge-shaped elongate recess configured to receive the first inward-facing wedge-shaped elongate protrusion of the ground facing component such that the foot support component tilts when sliding towards the rim portion of the ground facing component.

What is claimed is: 
     
         1 . A midsole for a sports shoe, comprising: 
 a foot support component comprising a rim portion comprising a first inward-facing wedge-shaped elongate protrusion; and   a ground facing component slidably arranged at least partially inside the foot support component, the ground facing component comprising: 
 an outsole; and 
 a first outward-facing wedge-shaped elongate recess configured to receive the first inward-facing wedge-shaped elongate protrusion; 
   wherein the foot support component and the first outward-facing wedge-shaped elongate recess are configured to tilt relative to the outsole when the foot support component slides in a lateral or medial direction relative to the ground facing component.   
     
     
         2 . The midsole of  claim 1 , wherein the first inward-facing wedge-shaped elongate protrusion is located at least partially in a metatarsal portion of the midsole. 
     
     
         3 . The midsole of  claim 1 , wherein the first inward-facing wedge-shaped elongate protrusion is located at least partially in a toe portion of the midsole. 
     
     
         4 . The midsole of  claim 1 , wherein the foot support component comprises a second inward-facing wedge-shaped elongate protrusion and the ground facing component comprises a second outward-facing wedge-shaped elongate recess configured to receive the second inward-facing wedge-shaped elongate protrusion. 
     
     
         5 . The midsole of  claim 4 , wherein the first inward-facing wedge-shaped elongate protrusion is arranged on a lateral side of the midsole and the second inward-facing wedge-shaped elongate protrusion is arranged on a medial side of the midsole. 
     
     
         6 . The midsole of  claim 1 , wherein the first inward-facing wedge-shaped elongate protrusion defines a first cross-sectional protrusion angle and the first outward-facing wedge-shaped elongate recess defines a first cross-sectional recess angle, and the first cross-sectional recess angle is smaller than the first cross-sectional protrusion angle. 
     
     
         7 . The midsole of  claim 1 , wherein the foot support component is connected to the ground facing component by a compliant coupling such that the foot support component is movable relative to the ground facing component. 
     
     
         8 . The midsole of  claim 7 , wherein the compliant material comprises a foam material. 
     
     
         9 . The midsole of  claim 7 , wherein the compliant coupling comprises one or more of a foam material, a plurality of columns and/or bars, or a lattice structure connecting the foot support component and the ground facing component. 
     
     
         10 . The midsole of  claim 1 , wherein a surface of the first outward-facing wedge-shaped elongate recess is coated with a material having a lower friction than another material of the ground facing component. 
     
     
         11 . The midsole of  claim 10 , wherein the material is co-molded with a portion of the ground facing component forming the first outward-facing wedge-shaped elongate recess. 
     
     
         12 . The midsole of  claim 1 , wherein the first inward-facing wedge-shaped elongate protrusion comprises a concave surface. 
     
     
         13 . The midsole of  claim 1 , wherein the first inward-facing wedge-shaped elongate protrusion comprises a void. 
     
     
         14 . The midsole of  claim 13 , wherein the void is filled with a foam material. 
     
     
         15 . The midsole of  claim 1 , wherein the first inward-facing wedge-shaped elongate protrusion forms a spring-like structure. 
     
     
         16 . The midsole of  claim 1 , wherein the foot support component comprises a circumferential rim portion protruding from an upper surface of the foot support component. 
     
     
         17 . The midsole of  claim 1 , wherein the foot support component forms a footbed. 
     
     
         18 . A sports shoe, comprising: 
 the midsole of  claim 1 ; and   an upper.   
     
     
         19 . The midsole of  claim 1 , wherein the first outward-facing wedge-shaped elongate recess defines a space between the ground facing component and the foot support, wherein the first inward-facing wedge-shaped elongate protrusion is configured to close the space when the foot support component slides in a lateral or medial direction relative to the ground facing component. 
     
     
         20 . A midsole for a sports shoe, comprising: 
 a foot support component comprising a rim portion comprising a first inward-facing wedge-shaped elongate protrusion; and   a ground facing component slidably arranged at least partially inside the foot support component, the ground facing component comprising: 
 an outsole; and 
 a first outward-facing wedge-shaped elongate recess configured to receive the first inward-facing wedge-shaped elongate protrusion; 
   wherein the first outward-facing wedge-shaped elongate recess defines a space between the ground facing component and the foot support, wherein the first inward-facing wedge-shaped elongate protrusion is configured to close the space when the foot support component slides in a lateral or medial direction relative to the ground facing component.
