I'm a 10 with slightly wide feet and the normal 10 fits well. I also ordered the wide 10, and I was swimming in them.  They are comfortable, but they do have a non-youthful look. I figured I could overlook that for the sake of healthy joints, but they are too clunky for some outfits.  The biggest negative is there is no ventilation. They make my feet sweat almost instantly..... so, I can't wear them unless it's cold outside.  The inside is all lined with cotton, so I imagine that is the main problem.
