Abstract
An air bladder boot fitting device facilitates snug fitting to prevent unintended removal of a boot. The device includes a boot having a sole and an upper coupled to and extending upwardly from the sole. The upper includes a shaft section extending downwardly from an open upper edge. A bladder is coupled to the upper and positioned within an interior of the boot. The bladder extends along the shaft section for securing a foot within the boot when the bladder is inflated. A bulb valve is coupled to the bladder for inflating the bladder.
