Abstract
An article of footwear is disclosed that includes a fluid system having a pump chamber and an inflatable pressure chamber. The pressure chamber is configured to extend at least partially around the pump chamber to limit the pressure of a fluid within the pressure chamber. The relative elevation of the pump chamber and pressure chamber may be selected, for example, such that the pump chamber is within an elevation defined by the upper and lower surfaces of the pressure chamber. The fluid system may be substantially formed from a pair of polymer layers that are bonded together to form the pump chamber and the pressure chamber, and the fluid system includes valves located between the layers.
