Semi-finished product for producing an innder sole or insole and inner sole or insole produced therefrom

Abstract

In order to increase the efficiency of insoles or shoe inserts, it is proposed to start from a semi-finished product ( 100 ) having a foam material layer which has a plurality of integrally formed raised sections on the upper side. According to the invention, the raised sections ( 120 ) or at least one of the raised sections should comprise one central raised section and a raised section completely or partially surrounding said central raised section, thus forming a plurality of massage edges. The probability of stimulating the desired reflex zone is hereby increased.

1 . A semi-finished product for fabricating an insole consisting of an elastic foam material layer corresponding to the outline of a shoe, which on its upper side, starting from the base surface of the semi-finished product, has a plurality of integrally formed raised sections, likewise consisting of the same elastic foam material, in the region of reflex zones of the sole of the foot, wherein at least the raised section which massages the toe head of the large toe comprises at least one central and at least one peripheral elevation which form a plurality of massage edges. 
     
     
         2 . The semi-finished product according to  claim 1 , wherein both the at least one central elevation and peripheral elevation have ramp-like lateral inclinations starting from the basic sole, which open into a flat raised section. 
     
     
         3 . The semi-finished product according to  claim 1 , wherein measured from a normal to the base surface, the lateral inclination has an angle between 30° and 60°. 
     
     
         4 . The semi-finished product according to  claim 1 , wherein the at least one central elevation and at least one peripheral elevation which are disposed adjacently to one another, form at least one corresponding recess. 
     
     
         5 . The semi-finished product according to  claim 1 , wherein only the raised section which massages the toe head of the large toe is provided with at least one peripheral elevation. 
     
     
         6 . The semi-finished product according to  claim 5 , wherein in addition, the raised section used to massage the solar plexus is provided with at least one peripheral elevation. 
     
     
         7 . An insole or shoe insert fabricated from a semi-finished product according to  claim 1 , wherein the foamed material layer of the semi-finished product is disposed as a massage layer between a cover layer and a supporting layer. 
     
     
         8 . The insole or shoe insert according to  claim 7 , wherein the cover layer is made from leather or textile material. 
     
     
         9 . The insole or shoe insert according to  claim 7 , wherein the supporting layer is fabricated from a cellulose-based material or from plastic. 
     
     
         10 . The insole or shoe insert according to  claim 7 , wherein the cover layer is connected as a massage layer extensively following the contours of the semi-finished product. 
     
     
         11 . The insole or shoe insert according to  claim 7 , wherein the cover layer only follows the outer contours of the raised sections and bridges the intermediate spaces between the central elevation and the at least one peripheral elevation leaving free a cavity. 
     
     
         12 . The insole or shoe insert according to  claim 7 , wherein the elastic foam material of the massage layer has a hardness of less than 25° Shore A so that the hardness of the insole provided with the cover layer has a hardness of higher than 25° Shore A. 
     
     
         13 . The insole or shoe insert according to  claim 12 , wherein the elastic foam material of the massage layer has a hardness of between 10° and 20° Shore A. 
     
     
         14 . The insole or shoe insert according to  claim 12 , wherein the hardness of the insole or shoe insert provided with the cover layer has a hardness of between 30° and 40° Shore A.
