Abstract
A cushioning member for an article of footwear is provided having a series of interconnected chambers filled with ambient or slightly pressurized air. An impedance is provided between selected chambers, in order to restrict the flow of air between the chambers. The shape and structure of the impedance determines the nature of the air flow between chambers, such that the cushioning member can be tailored for various types of activities and body weights, by offering varying degrees of cushioning.
