Wearing medical grade socks or stockings are generally recommended by physicians for people who suffer from leg pain and aches, to treat venous insufficiency, embolism, and lymphedema. Wearing Compression socks and stockings provides a gradient pressure that causes leg veins to become constricted allowing the vein walls and valves in the veins to come closely together forcing the blood to flow and to help prevent edema. It is important to measure the ankle, and calf circumference when choosing the compression sock size. It is also important to know the pressure recommend by the physician before purchasing compression wear. Hospital grade double tread and single tread slipper socks are important for individuals who are prone to falls and are important part of fall prevention.
