A resilient cushioning device for incorporation in an article of footwear has chambers interconnected by a corrugated passageway. The passageway fluidly connects a heel region having at least one chamber and a forefoot region having at least one chamber. The corrugation of the passageway make the passageway adjustable so that the resilient cushioning device fits a plurality of different articles of footwear. For example the passageway is adjustable so that it is expandable lengthwise so that the resilient cushioning device fits a plurality of sizes of articles and/or so that it bends sideways so that the resilient cushioning device fits a plurality of configurations of articles of footwear.
