Thanks Irulan! I've wide-ish toes and a quite narrow heel...it can be challenging to find shoes that fit me. I've heard the same thing about 5-10, thanks for the comment. I think there are a couple of other women here who ride with Teva as well. I take a size 10 in athletic shoes, or a 41-42 in European sizing. Of course that all depends on how they are made.
