Designed for the demanding needs of farming, ranching and construction work, these Muck Grit Tall Steel Toe Men's Rubber Work Boots feature protective, puncture-resistant rubber overlays that remain flexible for easy mobility. Layered with a mesh lining for improved air circulation, the 5 mm neoprene is 100% waterproof and shock-absorbent. The material retains heat and flexibility, adjusting to the natural contours of the feet. Rubber cup outsoles on these men's rubber work boots increase shock absorbency while providing excellent grip, especially on concrete floors and uneven surfaces. They also add comfort to the soles of the feet while standing for long periods. The steel toe in these men's work boots provides good impact protection from falling objects. The Stretch-fit Comfort Topline hugs the calf area to seal in warmth and keep cold and debris out.
