I were a size 13 in all my shoes so I ordered a size 13. I have never had a problem with my shoe size and I don't buy my shoes in in any special width. I also know that my left foot is a little bigger then my right so I am not sure what the problem was with these shoes but when I tried them on my right foot fit perfect but when I tried to put on the left it felt like it was a size too small. I like the feel of the shoe on right foot and I wish it would have fit the same on left but no luck I had to return them and look for another pair that were for wider feet so my left foot wasn't so tight. It took me a while but I found a pair of ASICS Men's Split Second Wide Wrestling Shoe on Amazon and I ordered them to see if they fit any better since I can't seem to  find them at any local sporting goods stores they only sell the wide online according everyone I called. Overall these are really nice shoes well made and would order again if they came in wide for fat feet.
