These leg wraps inflate and deflate to improve circulation, soothe sore muscles, and reduce swelling in your lower extremities. Similar to hospital compression boots that stimulate circulation in sedentary patients, the leg wraps have six airbags that wrap around the entire leg and inflate and deflate to help blood vessels expand and contract. The compression intervals 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 and at varying intervals. Adjustable Velcro closures ensure optimal fit for all sizes.
