We had a discussion on Sidi fit just recently, you might find some good info there.
I think the general consensus was that they do run small. I wear a women's 10, and I generally take a 41-42 in Euro size shoes, but my Sidi Dominators are a women's 42.5.

Team Estrogen carries Sidi shoes, perhaps if you give them a call they can help you out on sizing details.
good luck, - Jo.
