Insole for shoes

Abstract

An insole is proposed for a shoe. The insole has a flat back side in direction of the shoe outsole and a dome-shaped structure on the front side. The dome-shaped structure has a base surface of a maximum of 25% of the insole surface; the dome-shaped structure is positioned under the cuboid bone of the shoe wearer. A longitudinal axis can be associated with the dome-shaped structure at its apex, wherein the longitudinal axis of the dome-shaped structure encloses an angle (φ) in a range from 5° to 75° with the longitudinal axis of the insole.

         16 . An insole for a shoe, comprising:
 a back side configured to face a shoe outsole;   a front side opposite the back side;   a dome-shaped structure arranged on the front side having a base surface being a maximum of 25% of the insole surface positioned substantially under a cuboid bone of a shoe wearer; and   a longitudinal axis associated with the dome-shaped structure at an apex of the shaped structure, wherein the longitudinal axis of the dome-shaped structure encloses an angle having a range from about 5° to about 75° with a longitudinal axis of the insole.   
     
     
         17 . The insole according to  claim 16 , wherein the dome-shaped structure is positioned under a medial side of the cuboid bone of the shoe wearer where the cuboid bone borders a navicular bone on one side and a calcaneus bone on an other side. 
     
     
         18 . The insole according to  claim 16 , wherein the base surface is a maximum of 15%, of the insole surface. 
     
     
         19 . The insole according to  claim 16 , wherein the base surface is a maximum of 10%, of the insole surface. 
     
     
         20 . The insole according to  claim 16 , wherein the dome-shaped structure has a longitudinal-transverse ratio in a range from about 1.2:1 to about 3:1. 
     
     
         21 . The insole according to  claim 21 , wherein the longitudinal axis of the dome-shaped structure extends along a medial edge of the cuboid bone and encloses an angle of 5° to 35° with the longitudinal axis of the insole. 
     
     
         22 . The insole according to  claim 16 , wherein the dome-shaped structure has a height in a range from about 3 mm to about 20 mm. 
     
     
         23 . The insole according to  claim 16 , wherein the dome-shaped structure is permanently connected to the insole. 
     
     
         24 . The insole according to  claim 16 , wherein each of the insole and the dome-shaped structure have a respective connection components, wherein the connection component of the insole are formed with the connection components of the dome-shaped structure for detachable connection of insole and dome-shaped structure. 
     
     
         25 . The insole according to  claim 24 , wherein the connection components are at least one of hook-and-loop strips, recessed grooves in the insole and springs engaging in the grooves under the base of the dome-shaped structure, and recessed grooves in the base of the dome-shaped structure and springs engaging in the grooves at the front side of the insole. 
     
     
         26 . The insole according to  claim 25 , wherein the recessed grooves in the insole extend at an angle of about 80° to about 100° to the longitudinal axis of the dome-shaped structure. 
     
     
         27 . The insole according to  claim 25 , wherein the recessed grooves in the base of the dome-shaped structure extend along the longitudinal axis of the dome-shaped structure. 
     
     
         28 . The insole according to  claim 25 , wherein the respective recessed grooves are undercut and the respective springs are formed to widen outward. 
     
     
         29 . The insole according to  claim 16 , wherein the insole is produced as an insert for certain shoes. 
     
     
         30 . The insole according to  claim 16 , wherein the insole is an integral component part of the shoe.
