This has been a pretty mild winter in Minnesota, but I still love wearing these boots.  They are ultra comfortable and more than wide enough for me, which is important because I have a bit wider foot.  They do get a little hot if you're just wearing them around and I wouldn't recommend wearing them to the mall or anything like that where you'll be walking long distances.  In the elements though they really shine.  So far no leaks and they have excellent grip in the snow.  I highly recommend these boots.
