I have fat feet, and I wear a size 12 wide. I ordered the 12 E, and they were long enough and wide enough, but not "tall" enough. I couldn't get the tops of my feet crammed in them, even when I loosened the laces. There's just no stretch to the canvas. They seemed like they'd be comfortable if I could just get them on! So those of you with fat feet, get something else!

Returning them was so easy though, and only took a few days.
