I walk my dogs twice a day regardless of the weather - snow, below zero - it doesn't matter.  Although we haven't had below zero weather yet, I can tell these boots will keep my feet warm and dry.  I've been tromping through a few inches of snow in the woods for the last couple of weeks.  These boots have kept my feet dry and are very comfortable.  I didn't have to break them in - they felt good from the first time I put them on.  AND, my socks stay put!  I've had so many boots that after a few minutes of walking, my socks start to slide off my foot.......so irritating.
