I normally wear size nine. The Teva Toachi sandals I ordered with Kimtah, were nine and fit fine. I ordered the Kimtahs 9 1/2 in case I ever wore thick socks. But I could barely get my bare fit into one shoe, extremely tight, no room in the toe box at all. If I order again, I will get 10 1/2. Shoe appears good quality, but sizing was way off
