I live in Alaska and with winter just setting in this is a great outdoor boot. I use them when clearing the snow from the driveway, walking the dog and other light outside work.

Pro's: Beefy tread, doesn't fill up with snow (or I would guess mud), they are pretty warm (I've been out in 0 and while walking they have kept my feet warm). Light weight for the size of the boot.

Con's: And the only reason for 4 stars rather then 5 is that the bridge of the boot is very tight. On the one hand it's nice as there isn't that sloppy "boot feel" but the loss of a star is due to how hard they are to take off. They are not so tight as to rub while wearing.
