This shoe does not run true to size. I wear a size 10, not 10.5, not 11, but a 10. Based on previous reviews, I ordered a size 11. They are still a bit snug. Not sure how comfortable they will be, but could tell by trying them on, that the padding leaves something to be desired. I am thinking that when I do wear these to work, I had better bring my Sketchers. While this is a cute shoe, it doesn't scream comfort when I tried them on.
