The shoes arrived quickly enough. I usually wear between a 6 and a 6.5, but I opted for a 6 because previous reviews said they ran big. Well, turns out that they're not quite the size I was expecting, and they're slightly too small. It's not a big deal for me, because I bought them to wear with a bridesmaid dress, not for casual wearing. It is a shame I don't plan on wearing them for more than a few hours at a time, but I don't think I could manage that with how snugly they fit.
