I have a relatively narrow foot and usually wear a US 9.5 narrow. Most of my Manolos are size 39. I have the raspberry color and love them! I was told to get a 39.5 in the Sedaraby, but they only had a 39. The 39 is actually too big, so a 39.5 would have been huge. I don't think I could have gone down to a 38.5 because they would have been too short. All that being said, I think they run a little big, but not enough to size down.
