Commercial-grade waterproof boots in 5mm neoprene, built for all-day work in mud, water, and cold. The Muckmaster is built for people who work in the wet. A 5mm neoprene bootie is 100% waterproof and flexes with the contours of your foot instead of fighting it, and a stretch-fit topline binding snugs to your calf to hold warm air in and cold air out. Inside, a 2mm thermal foam underlay at the instep adds warmth and an EVA molded midsole with a contoured footbed cushions long days, while a breathable mesh lining keeps your feet from steaming. Extended rubber overlays protect the high-wear areas and an aggressive MS-1 molded outsole grips rough, slick ground.
