The inflatable lining (10) is formed of first (12) and second (14) plastic sheets having the shape and size of the selected inner surfaces, e.g., a sole, or any portion of the upper surfaces of the footwear. The sheets are bonded together in a continuous seam (16) about their peripheral edges thereby forming a sealed interior chamber. The inflatable liner is provided with an air pump (50) that preferably is a flexible bulb (66) with an inlet valve which discharges into a flexible tube (70) which extends to a pressure control valve (68) and then to the interior chamber of the inflatable inner sole.
