This is the cozy muff that provides heat therapy to soothe and relax sore, tired feet. Only available from Hammacher Schlemmer, the quilted muff has imperceptible electric heating elements that surround the feet in a blanket of gentle warmth to help boost circulation, ease the pain of arthritis or chilblains, and shake off the chill from a day in the cold. As pampering as putting your feet up by a fire, the muff swaddles both feet at once and heats up quickly, reaching between 120° F to 130° F in only 10 minutes. It automatically shuts off after 30 minutes to prevent toasted tootsies. Crafted from a soft micro-plush material, the muff has a removable, washable sherpa lining to baby tired feet. The tethered controller adjusts the heat to one of three settings and stays hidden in an integrated zipper pocket when not in use. Plugs into AC. Navy. 14" L x 12" W x 9 3/4" H. (1 1/2 lb.)
