This plantar fasciitis therapy brace can be worn inside a casual shoe, allowing you to treat plantar fasciitis while performing your normal daily routine. The brace slips over a sock and straps to your ankle; its thin, contoured design enables you to walk or stand comfortably while an adjustable strap gently stretches and lifts the arch, providing relief to the plantar fascia. The brace has a patented lining that increases the temperature of your skin by up to 3° F, improving circulation and accelerating the healing process. The lining is made from a breathable material that wicks away moisture to ensure optimal comfort during extended wear. Universal design fits on either foot. Please specify unisex sizes S/M (Men's shoe sizes 6-9; Women's shoe sizes 6-10) or L/XL (Men's shoe sizes 10-13; Women's shoe sizes 11-14). (3 oz.)
