Hi, Pam - I'm a size 11 male shoe. I ordered a size 10, and it was way too big. I reordered a size 9, and it fits pretty good. I think I could even fit a size 8 (especially as the neoprene stretches over time). So as a woman, I would order at least 2, and probably 3 sizes smaller than your shoe size. Incidentally, these are well constructed, although the cuff seems just a little loose. But you'll tuck it under your wetsuit leg cuff anyway, so it's not an issue.
Pam R Thank you for the info :)
