Abstract: A cushioning member for an article of footwear is provided having a series of interconnected chambers filled with ambient or slightly pressurized air. Impedance means is provided between selected chambers, in order to restrict the flow of air between the chambers. The shape and structure of the impedance means 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.

Abstract: A supportive, lightweight athletic shoe construction is described which includes an inflatable upper and a sole. The upper includes a foot conforming support member, an inflatable exoskeleton and an overlay which inhibits outward bulging of the exoskeleton. The sole includes a rigid carrier element, a forefoot unit and a heel unit. The forefoot unit includes a plurality of components which are arranged to work with the biomechanics of the foot. The athletic shoe is structurally minimalistic and functionally efficient.

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.

Abstract: A support and cushioning system for an article of footwear. The system includes a resilient insert disposed between a midsole and an outsole of a shoe. The resilient insert includes several chambers disposed in a heel portion of the resilient insert These chambers are fluidly interconnected to each other via periphery passages. The resilient insert also includes several chambers disposed in a forefoot portion of the resilient insert. These chambers are also fluidly interconnected to each other. A connecting passage connects the chambers in the heel portion and the chambers in the forefoot portion of the resilient insert. A bladder having a fluidly interconnected heel chamber and forefoot chamber is also inserted above the midsole to provided added cushioning to the wearer. In one embodiment, the resilient insert contains air at ambient pressure and the bladder contains air at slightly above ambient pressure.
