I guess I am old school.I wear nothing but Sorels in the winter.I have worn them in waist deep snow working(with gators)/snowmobiling and fishing in sub zero temps.Supposedly good to -40 degree's..

With a good fit and modern inserts,there easy to walk in when everything is tight.I sometimes go barefoot just using the liner as socks for quick/short outings like slippers.
