These are great shoes, great looking and light too. Well built also but you definitely will need a size 12 if you wear a size 11. Don't try to get away with a half size larger. They will be too short. Cramping your big toes. Incidentally, this is the very first shoe I have even had to buy a size 12 in in my life. I am going to return mine if I can because a size 12 is too big for me. Seems like I can't win on this one.
