Insole

Abstract

The invention relates to an insole (1; 1a; 1c; 1d), which has an insole underside (5; 5a; 5c; 5d) and an insole upper side (2; 2a; 2c; 2d), the insole underside (5; 5a; 5c;5d) being intended to bear against at least part of a shoe sole (6; 6a; 6c), and the insole upper side (2) being intended to bear at least part of the surface of the sole of a foot. At least one region (3; 3a; 3c; 3d) is expediently provided that has a concave curvature. As a result of the concave curvature, the insole acts as a diaphragm spring which is formed as an individual spring and which can cushion loads during use. The load on the foot of a person using the insole is thus lessened, which improves posture. The stress on joints when exposed to prologend loading is also reduced.

1 . Insole, which has an insole underside and an insole upper side, the insole underside being intended to bear against at least part of a shoe sole, and the insole upper side being intended to bear at least part of the surface of the sole of a foot,
 characterized in that   at least one region that has a concave curvature is provided.   
     
     
         2 . Insole according to  claim 1 ,
 characterized in that   the at least one concavely curved region is provided for supporting the longitudinal arch of the foot, in particular the inner longitudinal arch of the foot.   
     
     
         3 . Insole according to  claim 1 ,
 characterized in that   a cavity between the insole underside and the shoe sole of a shoe into which the insole is placed is open to at least one side, preferably two sides.   
     
     
         4 . Insole according to  claim 1 ,
 characterized in that   the insole is formed in one piece.   
     
     
         5 . Insole according to  claim 1 ,
 characterized in that   the insole has a substantially constant thickness.   
     
     
         6 . Insole according to  claim 1 ,
 characterized in that   at least one fastening means is provided which is arranged to provide a a preferably detachable connection of the insole to a shoe into which the insole is placed.   
     
     
         7 . Insole according to  claim 6 ,
 characterized in that   the fastening means is provided in a front region in which a forefoot can rest against the insole underside, in a middle region on a side facing away from the at least one concavely curved region and/or in a rear region in which a heel can rest against the insole underside and in particular projects from the insole underside.   
     
     
         8 . Insole according to  claim 6 ,
 characterized in that   the fastening means is at least partially incorporated into the insole and/or flush with the insole underside.   
     
     
         9 . Insole according to  claim 6 ,
 characterized in that   the fastening means comprises a multi-part, preferably two-part magnetic fastening element.   
     
     
         10 . Insole according to  claim 1 ,
 characterized in that   the at least one concavely curved region has a reinforcing means which is preferably formed from a different material than the insole.   
     
     
         11 . Insole according to  claim 1 ,
 characterized in that   the at least one concavely curved region comprises a reinforcing means that is preferably integrally molded to the insole and/or is molded into the insole.   
     
     
         12 . Insole according to  claim 10 ,
 characterized in that   the reinforcing means is exchangeable and/or detachably attachable.   
     
     
         13 . Insole according to  claim 1 ,
 characterized in that   the insole is formed from a plastic, in particular polyethylene, polypropylene, a natural raw material, for example wood or cork, and/or a material comprising lignin and/or hemp fibers.   
     
     
         14 . Insole according to  claim 1 ,
 characterized in that   the insole is manufactured or manufacturable by injection molding, extrusion, deep-drawing and/or blow molding.
