"I normally wear a 10, but can occasionally size down to a 9.5. If you ever size down, do it with these boots! My foot slid way forward in the 10s, such that I could barely walk in them. The 9.5 fit very well, although I find the toes to be rather narrow. I don't think this will be a problem, as the leather is very supple, though the outside is a bit rougher than I expected. If you're looking for a sweetly tough boot, and can walk in heels, these are the boots for you."
