ABSTRACT:
An athletic shoe has two independent, inflatable chambers, one in the sole and one partially forming the shoe upper. The former chamber cushions impacts and displaces solid material from which the sole would otherwise comprise, and the second tightens the fit of the shoe on a wearer's foot. Each chamber has independent inflation and outlet valves. Resilient pilings distribute a wearer's weight over the sole, protecting the first chamber from deformation during activity. A pump is detachably mounted on the shoe tongue. The pump has a ring for attachment to a key ring as an alternative to being secured on the shoe tongue when not in use. A preferred inflation medium is helium.
