Offered only by Hammacher Schlemmer, and constructed from three therapeutic layers, these are the thermal slippers that help boost circulation and soothe foot pain. With a snug fit ideal for those who suffer from arthritis, diabetes, or cold, sensitive feet, the slippers’ outer layer provides light compression of the achilles tendon at the back of the foot and the plantar fascia ligament on the sole, helping to reduce inflammation and soreness. The middle layer traps warmth to raise skin temperature, promote healing and blood flow, and ward off chilblains. The soft inner lining wicks away moisture with a breathable band along the top of the foot that facilitates air flow to prevent overheating. The comfortable indoor booties have a rubberized anti-slip sole and pull loops for easy on and off. Loose fit, please order one size down.Unisex sizes S, M, L, XL. (10 oz.)
