Shoe-leveling insole

Abstract

A negative-heel insole comprising a substantially tapered body of material ( 30 ), having a predetermined thickness of the forefoot portion ( 32 ) of the insole, being substantially thicker than the predetermined thickness of the heel portion ( 34 ) of said insole. The base ( 30 ) of the insole is made of a flexible material that can be repeatedly bent or flexed without fracturing, such as ethylene vinyl acetate foam, polyurethane foam, polyethylene, rubber, leather, silicone, encased gel, etc. . . . In addition, a fabric layer top portion ( 20 ) is bonded with adhesive to the top superior surface of the base ( 30 ).

I claim: 
     
         1 . A shoe insole of the type comprising a substantially, longitudinally tapered body of material, having a predetermined thickness of the forefoot portion of the insole, being substantially thicker than the predetermined thickness of the heel portion of said insole, the improvement wherein said insole when placed in raised-heeled footwear or shoes of a pre-determined raised-heeled height, will have an approximate leveling effect on the human foot, whereby when wearing said raised-heeled footwear or shoes, the forefoot and the heel of the human foot will be positioned substantially level to each other, providing the benefits therein. 
     
     
         2 . The insole of  claim 1  wherein said tapered body of material is composed of ethylene vinyl acetate foam. 
     
     
         3 . The insole of  claim 1  wherein said tapered body of material is composed of polyurethane foam. 
     
     
         4 . The insole of  claim 1  further including a thin fabric top layer bonded with adhesive to the superior surface of said tapered body, covering the entire superior surface of the insole. 
     
     
         5 . The insole of  claim 1  wherein said tapered body is wedged by increasing its thickness of the insole transversely across the forefoot and heel regions of the insole, thereby providing for a means to help prevent excessive foot pronation. 
     
     
         6 . The insole of  claim 1  further including a cushioning enhancer positioned under the forefoot region, whereby cushioning is enhanced. 
     
     
         7 . The insole of  claim 1  further including a cushioning enhancer positioned under the heel region of said insole, whereby cushioning is enhanced. 
     
     
         8 . The insole of  claim 1  further including midfoot, medial and lateral longitudinal arch stabilizer positioned beneath the midfoot, medial and lateral longitudinal arch region of said insole, whereby midfoot and medial longitudinal arch support of the human foot is enhanced. 
     
     
         9 . The insole of  claim 1  further including heel cup, medial and lateral arch sidewalls, whereby the hindfoot and midfoot regions of the human foot are cushioned and stabilized by said sidewalls. 
     
     
         10 . The insole of  claim 1  wherein said tapered body is wedged by increasing its thickness of said insole transversely from a medial to lateral direction across the midfoot region of said insole, thereby providing for a means to improve medial longitudinal arch support, and to help prevent excessive foot pronation. 
     
     
         11 . The insole of  claim 1  wherein the forefoot portion of said insole thickness ranges between 3 and 5 millimeters thicker than the heel portion of said insole. 
     
     
         12 . The insole of  claim 1  wherein the medial longitudinal arch region of said insole is elevated, when compared to the lateral longitudinal arch region. 
     
     
         13 . A shoe insole of the type comprising a substantially longitudinally tapered body of material, having a predetermined thickness of the forefoot portion of the insole, inclusive of the region of the insole beneath the metatarsal heads and the toes of the human foot, said forefoot portion having an increased thickness, when compared to the hindfoot or heel portion of said insole, most specifically the region where the calcaneus bone lies, the improvement wherein said insole when placed in raised-heeled footwear or shoes of a predetermined raised-heeled height, will have an approximate leveling effect on the human foot, whereby the forefoot and the heel of the human foot will be positioned substantially level to each other. 
     
     
         14 . The insole of  claim 13  wherein said tapered body of material is composed of ethylene vinyl acetate foam. 
     
     
         15 . The insole of  claim 13  wherein said tapered body of material is composed of flexible materials that can be repeatedly bent or flexed without fracturing. 
     
     
         16 . The insole of  claim 13  further including a thin fabric top layer bonded with adhesive to the superior surface of said tapered body, covering the entire superior surface of the insole. 
     
     
         17 . The insole of  claim 13  wherein said tapered body is wedged by increasing its thickness of said insole transversely from a medial to lateral direction across the midfoot region of said insole, thereby providing for a means to improve medial longitudinal arch support, and to help prevent excessive foot pronation. 
     
     
         18 . The insole of  claim 13  wherein said tapered body is wedged by increasing its thickness of said insole transversely from a medial to lateral direction across the forefoot and hindfoot or heel regions of the said insole, thereby providing for a means to help prevent excessive foot pronation. 
     
     
         19 . The insole of  claim 13  further including a cushioning enhancer positioned under the forefoot and heel regions of said insole, whereby cushioning is enhanced. 
     
     
         20 . The insole of  claim 13  further including midfoot and medial longitudinal arch stabilizer positioned beneath the midfoot, inclusive of the medial arch region of said insole, whereby midfoot and medial longitudinal arch support of the human foot is enhanced.
