An inflatable boot and method for its manufacture, in which the boot includes a bladder for encasing at least a portion of a human foot and at least a portion of an ankle. The bladder is defined by an inner and an outer layer of substantially gas-tight material, and includes fluidically interconnected wall and sole portions. The wall portions are sized and shaped for collectively encasing a human ankle and the sole portion is sized and shaped for encasing a sole of a human foot. A structural interconnection joins the inner layer of the bladder substantially directly to the outer layer at a location interposed the sole portion and one of the wall portions to create a foot-supporting contour for the sole portion of the bladder when the bladder is inflated. The bladder for the boot is manufactured in a flattened condition, and then folded over and joined at seams to define a boot. |
