All Day Performance: Inside the boot is moisture wicking nylon, shock absorbing removable comfort cork EVA with memory foam footbed for long-lasting comfort, and exclusive ScentBan technology in the footbed and lining eliminates odor so you can go all day for your trophy. Tough Terrain Traction: Bulls-Eye Air Bob Aggressive sole provides excellent traction, and a built-in steel shank ensures more stable footing in your calves while improving underfoot support. Waterproof Design: Full grain leather upper is protected with GORE-TEX waterproof technology blocking moisture from the outside, while allowing sweat vapor to pass right through to evaporate, keeping your feet dry and comfortable in all conditions. Insulated: A layer of 1000g 3M Thinsulate Ultra insulation keeps you warm. The ultimate insulation for cold weather boots because the material is thin, warm and lightweight, with the durability to withstand long hours of hard wear and keep feet warm even in damp conditions. Resoleable Platform: The Goodyear Welt sole construction prevents water intrusion and adds strength and durability to the boot making it long lasting. It allows the boot to be resoled to extend the life of the boot.
