My son would keep it if it was the right size. I bought this for my 19 year old son who wears a size 7 because the retail stores don't stock his size. When he fastened the Velcro near his toes to adjust it better, the tip of the strap touched the ground and there was still too much room at the heel. It is very difficult to find him a pair of shoes that will fit him and support his flat feet.
