Fleece Lining, an additional 5mm CR flex-foam bootie, and 2mm of thermal foam under the footbed, allows this boot the additional warmth for a comfort range to 40 degrees F below. The stretch-fit top line binding fits snug to the calf and keeps the warmth in and the bitter cold out. It is 100% waterproof, lightweight, and flexible. How about a 10mm kick rim for hands free removal, added toe protection with a wrap-up bumper and a MS-1 molded durable rubber outsole allows for maximum protection and stability when venturing in search of game.
