Shires Tendon Therapy Ice/Heat Boots Pair are an all in one therapy boot. Soak in warm water, microwave for hot therapy to soothe aching legs, or put in the freezer for cold treatment. Removable inserts velcro onto the insulating neoprene outer boot, allowing you to easily freeze/warm, apply, and clean these boots. You no longer need several hands to apply cold or hot packs with bandages, as these are as easy as splint boots to apply with hook and loop, touch tape fasteners.
