The fit is good, especially if you have wider feet or a long second toe. They are very comfortable, and while they do not seem to strech much, they will conform to your foot. For a fit that allows edging and smearing, I'd suggest a 1/2 size below your street shoe. They get smelly (dead animal?), so be sure to let them air out or your pack will also smell. This is my second pair.
