The insole of claim 1 wherein the stability cradle has a length essentially equivalent to the length from the calcaneus through the metatarsal joints of a user's foot for which said insole is designed to be used. 14. An insole for use in a shoe having a top side for contacting a user's foot and a bottom side for contacting the bottom interior surface of a user's shoe, comprising: a. a base, said base having a base top surface and a base bottom surface, said base having a heel end, a toe end, a medial border and a lateral border, said medial and lateral borders extending from said heel end to said toe end along the medial and lateral sides of the insole, respectively, said base bottom surface defining: (i) a forefoot area extending from the toe end of said base to a location adapted to correspond to an area behind a metatarsal head area of the feet,(ii) a midfoot area adapted to extend from the metatarsal head area of the feet to an edge that lies forward of the calcaneus of the foot,(iii) a heel area that extends from said midfoot area to said heel end,(iv) a forefoot pad indentation area located in said forefoot area, and adapted to extend from under the hallux of the foot from near the distal end of the base proximally to the front of the first metatarsal head, and(v) a stability cradle indentation area located essentially along the midfoot and heel areas of the insole,b. a continuous extended heel pad located in said lateral midfoot area that extends along the lateral side of the insole from the midfoot area to the heel area and from the lateral side to the medial side in the heel area, said extended heel pad being affixed to said base bottom surface of said base;c. a stability cradle made of semi-rigid material and secured to said stability cradle indentation area of said base bottom side, said stability cradle having rib openings and an extended heel pad opening that allows the extended heel pad to extend there through;d. a forefoot pad secured to said forefoot pad indentation area, said forefoot pad adapted to extend laterally and proximally under the lesser metatarsal heads of the foot to beneath the greater metatarsals; ande. a supplemental heel pad affixed to said extended heel pad and located over a portion of the extended heel pad on the medial side of said heel area. 15. The insole of claim 14 wherein the supplemental heel pad is made of a firmer material than the material of the extended heel pad. 16. The insole of claim 14, wherein the firmness of the supplemental heel pad is in the range of Shore C 45-50 and the firmness of the extended heel pad is approximately Shore C 60. 17.
