Claims20
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.
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.
