The FootSmart Plantar Fasciitis Support uses elastic tension to relieve pain and promote muscle development. Skin remains dry and comfortable. Wear over socks during the day and at reduced tension at night. Order by Men's / Women's shoe size and left or right foot above. Caution: Not recommended for those with diabetes or poor circulation.
