The fleece-lined massage boot with heat features two powerful motors, separate heat control and two massage levels. The Massage Foot Warmer has a soft, removeable fleece lining that is machine washable and is treated to prevent lingering foot odour. The exterior material is a soft-touch micro-suede and the boot will fit up to a man's size 15 foot. The handheld controller adjusts both heat and massage; soothing cold, tired or aching feet.
