I'm on the small side of a size 7, but in this shoe I'm an 8. I just tried on the 7's and they're too narrow. I can put them on, but not for wearing. I do have a short, wide foot, so that many styles of shoes are too narrow, but most of the time I can fit a medium width. I exchanged for an 8, which I haven't received yet, and I'll update this review at that time, but I just wanted to add to the warnings about sizing. Definitely order up, unless you're on the lower side of your size and have a very narrow foot. Update: The 8 fits, but now that I can get them on, I don't like them. I think they look like slippers on me. However, I think someone who dresses stylishly could make them look good with the right fashion, but on me they look like slippers.
