So I wear a men's 10.5/women's 12 when measured and have a fairly narrow foot.  This boot fits me great with athletic socks on.  They're a little tight, but still alright, when I'm wearing thick wool.
The footbed is very thick and comfortable.  They are certainly not the most attractive boots I've ever seen, and they aren't as polished looking as they are in the picture, but I wear them to school almost every day and I love them.  I have not had any problems with traction, but I have also not tried to do construction in the rain while wearing them.
All in all very comfortable low boots that seem extremely sturdy.  I will try to report back in a year with how they're holding up.

**Just a bit of an update after a couple months of wearing these almost every day.  They're holding up fairly well (some of the stitching seems to be loose around the sides) but I wore them in Chicago on icy sidewalks and I got no traction whatsoever.  I think if I still lived there (as opposed to Atlanta) I would consider different every day shoes.
