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.

Abstract: A shoe construction having an energy return system together with features providing cushinoning and stability. The energy return system includes a rigid frame having a torsional rigidity bar in the midfoot area integrally connecting annular walls in the forefoot and heel areas of the midsole. A net of monofilaments or fibers is secured under tension in the areas defined by the annular walls with the net positioned over an open area in the midsole. A cantilevered system of support pads is positioned in the arch area to support the medial side of the midfoot.
