I wear these all the time for working outside on our property in rainy Oregon. They are totally waterproof and very comfortable. It's not that cold here so I only wear thin wool socks with them (if at all). Since these only come in whole sizes, I took other reviewers' advice and got size 8 (I'm normally a 7.5), although there is a little extra room since I don't wear thick socks. I get great traction in the mud, but I haven't worn them in snow or ice. Seriously, these are my favorite work boots ever.
