The dependability of a Muck Boot is now in a steel toe work boot. The Chore can take on the worst of the worst. The upper has a stretch-fit binding keeping warm in and cool out as well as a seamless, quick-clean rubber overlay. A steel shank provides additional support, with triple reinforcement in the toe area and quadruple reinforcement in the heel. A durable, lightweight rubber outsole adds unbeatable traction in all conditions.Specifications and Features: 5mm NEOPRENE bootie with four-way stretch nylon 100% waterproof Boot Height: 16.54in Durable, lightweight rubber outsole EH Rated Meets ASTM F2413-11 M I/75 C/75 EH Quick-clean rubber overlay Shaft Circumference: 17in Steel Shank Steel shank for additional arch support Steel toe Stretch-fit topline binding snugs calf to keep warmth in and cold out Upper is triple reinforced in the toe area and quadruple reinforced in the heel area Weight: 4.87 lbs size 9
