I'm a tall guy (6ft 2in, 375lbs) with very, very wide feet. My actual foot size is 10.5 6E US. I've never heard of this brand, I usually buy New Balance or Sketchers but thought I'd give this brand a try. I bought the US10.5 XX-wide and they fit and feel really good. They might have been a little tight for a day, but then I had a feeling that normal worn shoes would feel. It might be a little tight in the tongue area, but I didn't notice it as much as other people. There was just enough velcro to accommodate my large wide foot. Overall highly recommended as I was pleasantly surprised.
