I agree with scubasnyder... definitely go a few sizes bigger than usual. I don't really like bouldering in these shoes, since i have a pair of anasazis, but the feeling of being able to toe into absolutely ANYTHING on a sport route is incredible. It sounds like Kitarra got a bum deal - sorry. Although if you are going to buy this shoe, i would mention the heel area as the weak point. The shoe does not have any rubber on the sides of the heel, and the heel does feel very loose at all times. In fact, heel-hooking just doesn't work very well.
