I get cold feet and these are really warm!  They are great in cold weather, however, I can't wear them for any time indoors, like sitting in a movie theatre for a couple hours--they get too hot.  Mine were pretty snug at first, even with thin socks.  Eventually, however, the boots stretched enough to be comfortable, even with heavy socks.  Also, the zipper/fold rubbed against my ankle for a for few days, but that problem went away after a while, too.  They are clunky and can be awkward while driving.
