These leg wraps inflate and deflate to improve circulation, soothe sore muscles, and reduce swelling in your lower extremities. The leg wraps have six airbags that wrap around the entire leg and inflate and deflate to help blood vessels expand and contract. Similar to hospital compression boots that stimulate circulation in sedentary patients, the wraps use compression intervals to stimulate circulation in the thighs, hamstrings, calves, and feet and help facilitate blood flow back to the heart. The corded remote allows you to select from three levels of intensity and choose from seven programs that pinpoint different areas. Adjustable hook-and-loop closures ensure optimal fit. Fits calves 16"-18", thighs 23"-25", feet 6-11 3/4" long. Plugs into AC. Set of two wraps. 33 1/2" H x 30 1/4" W x 3/4" D.
