Insole and shoe comprising a removable insole

Abstract

An insole designed for supporting a foot after the insole is inserted in a shoe and which abuts a sole section of the shoe includes an integral plastic material forming a flexible planar base layer out of which numerous resilient studs arise. The insole is easily manufactured and provides a comfortable feeling. The planar base layer is designed as a contact surface for the foot. The studs are designed to extend from the base layer to the sole section of the shoe, and are shaped of different heights so that upon weight-loading by the foot the flexible planar base layer is deformed so as to conform with the shape of the underside of the foot as a three-dimensionally shaped footbed.

1 . An insole for supporting a foot after the insole is inserted in a shoe so as to abut a sole section of said shoe, comprising:
 a flexible planar base layer;   numerous resilient studs arising out of said base layer, wherein said based layer and said numerous resilient studs are integrally formed from a plastic material,   wherein   the base layer includes a foot contacting surface for contacting a surface of a foot, and a studded surface opposite the contacting surface,   the resilient studs extend from the base layer from the studded surface toward the sole section of the shoe when the insole is inserted in the shoe, and   the resilient studs are shaped of different heights so that upon weight-loading by the foot on the insole when it is inserted in the shoe, the base layer is deformed so as to conform with the shape of the underside of the foot as a three-dimensionally shaped footbed.   
     
     
         2 . An insole according to  claim 1 , wherein the numerous resilient studs include relatively smaller height studs in a middle of a heel portion and in a toe portion of the insole, and relatively larger height studs at an edge of the heel portion as well as in an intermediate section of the insole between the heel portion and the toe portion. 
     
     
         3 . An insole according to  claim 2 , wherein the intermediate section is an instep portion of the insole. 
     
     
         4 . An insole according to  claim 1  wherein at least some of the resilient studs are massive studs. 
     
     
         5 . An insole according to  claim 1  wherein at least some of the resilient studs are configured to widen their diameter when being compressed under weight-load. 
     
     
         6 . An insole according to  claim 1 , further comprising a number of ventilation holes positioned within the base layer in interspaces between the resilient studs. 
     
     
         7 . An insole according to  claim 1  wherein the plastic material of the insole is a gel. 
     
     
         8 . An insole according to  claim 7 , wherein the gel is a polyurethane gel. 
     
     
         9 . An insole according to  claim 7 , further comprising a film of a non-adhesive material covering the gel. 
     
     
         10 . An insole according to  claim 9 , wherein the film is a polyurethane film. 
     
     
         11 . A shoe, comprising:
 a sole section;   an upper section; and   a removable insole according to  claim 1  wherein the insole abuts the sole section by means of top portions of resilient studs of the insole.
