Abstract
A reactive energy fluid filled cushioning and stabilizing apparatus in a shoe is comprised of one or more anatomically shaped fluid filled bladders that are positioned in the forefoot, arch and/or heel areas of the shoe. The bladders assume a complementary custom fitting configuration to the contours of a foot inserted in the shoe. In variant embodiments of the apparatus, the fluid filled bladders are positioned separate from each other in the forefoot, arch and heel areas of the shoe and are interconnected in fluid communication by fluid conducting channels, or the bladders are positioned independent of each other in the forefoot, arch and heel areas of the shoe.
