Abstract
An article of footwear with a dynamically-controlled cushioning system is disclosed. The cushioning system includes a sealed, fluid-filled bladder formed with a plurality of separate cushioning chambers, and a control system. The control system, which includes a CPU, pressure sensors and valves, controls fluid communication between the chambers to dynamically adjust the pressure in the cushioning chambers for various conditions such as the activity that the footwear is used in, the weight of the individual and the individual's running style. Certain adjustments can be made while the footwear is in use.
