Abstract
A cushioned, height-adjustable shoe has a hollow for receiving a wearer's foot, the hollow defined by a base on which the wearer's foot rests and an enclosure surrounding at least a portion of the wearer's foot; and within the hollow, an inflatable bladder associated with the base for lifting the wearer's foot to a degree determined by the amount of inflation. The bladder has a collapsable wall that may include pleats. In one embodiment, the bladder is wedge-shaped with a maximum height along the rear (heel) segment, and is disposed between the sole of the shoe and a soft but relatively thin foot pad so as to be invisible during use. In a second embodiment, the bladder constitutes the sole of the shoe, and once again is is defined peripherally by a set of expandable pleats. The bladder is accessed for inflation by means of a pump located beneath the shoe pad.
