Ready for winter's worst, Tundra’s rugged “Mitch” boot is made with heavy foam insulation rated to -30º F. It has easy-care nylon and suede uppers with convenient front zipper. A heavy-duty rubber bottom with snow-biting lug tread makes this the weather-beater you need. Men's whole sizes 7 to 13 in XW(4E) width. (Seasonal style: some sizes may sell out early.)
