I'm a size 8 to 8.5 and the 8 was too small/tight. I exchanged for a size 9 and they fit pretty well -- because they're larger than I technically wear, the shoes don't stay on my feet as easily so I have to grip with my toes more. That makes the shoes slap on my feet when I walk. Not a deal breaker, just a little noisy! I'm keeping them because they are comfortable and very nice looking.
