Abstract (en)
[origin: WO9314659A1] Inflatable footwear is disclosed in which an inflatable bag (25) under the foot is formed by two sheets of material welded together. Interior welds (28) are provided to moderate the thickness of the inflatable bag. A foam layer (62) having apertures (64) is positioned adjacent to the inflatable bag. The apertures (64) overlie the interior welds (28, 28') and are sized larger than the interior welds. Also described is a slide valve system (Fig. 11) which enables selective inflation of individual bladder chambers (32, 30).
