This is much larger than it appears. I gave 4 stars because the thong that goes in between the toes was painful. A standard wall doorstop is deeper from the wall than the distance the hooks come out from the wall. ***Original review***Ive had mine for a little over two years now and I wear these CONSTANTLY. Grey foam turned a dark yellow over the last year. Cons and Oks:__________? You need a Facebook account to use this machine. There?s no support on the sides or the bottom. This product was decent but I expected something a little roomier. Noise cancellation. Have other Easy Spirit shoes, and they are always perfectly sized & supportive.
