ABSTRACT:
A fluid filled support system for footwear having a closed system of interconnected pods filled with fluid for providing enhanced cushioning, support, and fit. The fluid filled support system includes a support member which completely surrounds a wearer's foot to provide cushioning and support to the wearer's entire foot. A plurality of fluid-containing pods are positioned within the support member spaced apart from one another and at least partially filled with a fluid for absorbing shocks encountered by the footwear. A plurality of fluid communication channels are positioned between the fluidcontaining pods for interconnecting the pods and maintaining all of the pods in fluid communication with one another. Each fluid-containing pod includes at least three fluid communication channels extending from the pod to attach the pod to at least three adjacent fluid-containing pods. The fluid communication channels may intersect with one another to provide additional fluid pathways for connecting additional fluid-containing pods to each pod. As pressure is applied by a wearer's foot, the support member reacts by forcing the entrapped fluid to redistribute through the interconnected pods. Once the area of high pressure is relieved, the shoe again reaches a level of equilibrium. This flow of redistributing fluid between interconnected pods provides the desired cushioning and support of the wearer's foot, wherein the multiple fluid paths connected to each pod provide a more responsive cushioning system.
