So I'm looking for Sidi sizing advice since I *ahem* want to use the 20% coupon and have waited until the ever helpful TE folks aren't around....

I wear between an 8.5 and a 9 in women's shoes. I have a pair of 41 Sidis, and purchased a pair of 41.5 Sidis after my feet swelled and I ended up with black toenails on a long ride. I know the Sidi boots are men's - will the 42 be way, way too large on me? Thanks for any thoughts
