The -60 to 30F comfort rating of our MTX 17-inch 1,600-gram Insulated Boots makes them ideal for late-season hunts in extreme conditions. Durable and incredibly flexible, their combination of 5mm neoprene and hand-crafted vulcanized rubber construction resists aging, naturally traps and retains body heat, and controls odor. With the addition of 1,600 grams of Muddy insulation in the toe boxes, you'll enjoy plenty of extra warmth through the coldest conditions. The 17-inch, roll-down calf pipes accommodate tucking your pant legs inside. Integrated into the footbeds are 4-inch steel shanks that keep feet supported all day. Rugged rubber outsoles provide 44 traction, keeping you sure-footed on all types of ground in any weather. Start your next outing with your best foot forward, thanks to Muddy.
