I accidentally ordered this boot in my size, but the wider width. Not too shabby! There's wiggle room, but I think it will accommodate the thick winter socks nicely. I'm a 8.5 and that's what I got so I'd say they're true to size. I think I'll come back after it's started snowing (Im in MN so it shouldn't be too far off) and update my review to mention what performance is like. But I'm please with the look and craftsmanship thus far :)

UPDATE: So much for a snowy winter - I've been wearing these boots lots though. The traction is so-so, not as grippy as I expected but these have been perfect for going to & from work, and picking up the kids (aka chasing them thru what little snow we've had). They've been warm and have held up nicely. I've used them during shoveling and I did slip so I'm changing my rating from a 5 to a 4 - these aren't for shoveling, but for everyday wear.
