This is the calf wrap that improves circulation to reduce swelling and relieve pain. Small, battery powered motors inside the wrap generate a subtle vibration that facilitates blood flow to the legs, soothing sore muscles. The vibrations also relax stiff, sore areas and the wrap provides a firm compression to improve flexibility. Made from soft, breathable cotton, the wrap simply slides on and its thin, flexible construction allows it to be worn under clothing without restricting movements. The vibration is turned on with the touch of a button and two adjustable bands keep the wrap in place. Motors are removable and the wrap is machine-washable. One size fits all.
