A work boot with a Stretch-fit topline binding stays snug at the calf to keep warmth in and cold out. The Muck 5mm NEOPRENE bootie with four-way stretch nylon is 100% waterproof, lightweight and flexible. Wearers can count on a durable, lightweight rubber outsole, while the upper is triple reinforced in the toe area and quadruple reinforced in the heel area. These Muck Boots feature a steel shank for additional arch support and a quick-clean rubber overlay. Color: Black. Men's 13.
