I normally wear a size 11. I ordered a size 11, and received a size 9. I tried them on anyway since all the reviews said they ran large. Well, the size 9s were just a little small on me. I ordered a size 11 again and received a pair that looked a bit different, but were marked size 11. They were also a little small on me. Not much different than the size 9.  Two pair so far, and nothing fits!
