I like these shoes alot. They make it really easy to stand on next to nothing. I wear a size 11 running shoe and bought 11's in these and they fit like a glove. They were a bit tight at first but stretched justttt a little to get that perfect fit. They wont stretch much because they are synthetic. The only issue I have with the shoe is that material on the top of the toe area flakes very easily. It is almost as if 5.10 did a half ass job with some spray on rubber. I'll be contacting them shortly to see if they have had any similar complaints.
