Abstract
A cushioning member for an article of footwear. The cushioning member is a flexible bladder having a fluidly interconnected heel chamber and forefoot chamber. The bladder is disposed above the sole and beneath the wearer's foot to provided added cushioning to the wearer. The bladder contains air at slightly above ambient pressure and can be formed by thermoforming or by welding two sheets of resilient, flexible material together. A connecting passage fluidly connects the heel chamber and the forefoot chamber. The connecting passage is narrow to control the flow of air between the two chambers.
