Footwear with an adjustable stabilizing system, in particular for pronation and/or supination control

Abstract

A footwear has a sole that comprises an adjustable stabilising system, in particular to control phenomena of pronation and/or supination. The stabilisation system comprises at least one adjustment member capable of selectively taking at least two alternative positions within a respective seat present in a component of the sole, the adjustment member having a body with at least two portions or sectors that present different degrees of compressibility.

1 . Footwear having a sole that comprises an adjustable stabilising system, in particular to control phenomena of pronation and/or supination, wherein the adjustment system comprises at least one adjustment member capable of selectively taking at least two alternative positions within a respective seat present in a component of the sole the adjustment member having a body with at least two portions or sectors that present different degrees of compressibility.  
     
     
         2 . Footwear according to  claim 1 , wherein different positions of said member within said seat correspond to different positions of one said sector with respect to a specific zone of the peripheral profile of the sole.  
     
     
         3 . Footwear according to  claim 2 , wherein 
 said seat extends between a medial zone and a lateral zone of the peripheral profile of the sole, and    in at least one of said positions, a first of said sectors lies at least partially in said medial zone and a second of said sectors (S 1 ) lies at least partially in said lateral zone.    
     
     
         4 . Footwear according to  claim 1 , wherein said member is angularly rotatable or can be moved in, or with respect to, said seat.  
     
     
         5 . Footwear according to  claim 1 , wherein said seat and said member have substantially complementary peripheral profiles.  
     
     
         6 . Footwear according to  claim 4 , wherein said component comprises the body of a midsole of compressible material, said member is approximately disk-shaped and said seat has an approximately circular section.  
     
     
         7 . Footwear according to  claim 4 , wherein said seat and said member have peripheral profiles each defining two or more projections or lobes.  
     
     
         8 . Footwear according to  claim 1 , wherein said seat communicates with at least one passage that opens onto a peripheral edge of said component of the sole, through said passage at least part of one of said sectors being visible and/or accessible from outside the footwear.  
     
     
         9 . Footwear according to  claim 8 , wherein said sectors have, at least in the respective parts visible through said passage, different colours or appearances or indications one from another.  
     
     
         10 . Footwear according to  claim 8 , wherein said passage is covered by an element formed at least in part of transparent material.  
     
     
         11 . Footwear according to  claim 4 , wherein said member is arranged to be displaced angularly between said alternative positions using a tool.  
     
     
         12 . Footwear according to  claim 1 , wherein each of said sectors presents at least one chamber containing a fluid, the chambers of different sectors being at different pressures.  
     
     
         13 . Footwear according to  claim 1 , wherein said seat is formed in a heel part of the sole.
