the support in the arches line up right with my foot, unlike others i've tried. the straps that go across the top of the foot have no give to them until you soak them or wear them while taking a shower and until they dry - they don't strech out but it does soften them a little. i also wanted to add that for the most part they are non-skid, i did slip/skid once when wearing them the shoe soul gripped and stopped the slip - i tried to make it do it again and couldn't (just say-n). i want another pair in a different color but not successful in finding any at this time.
