The Original Muck Boot Company Men’s Chore Cool Hi work boots were crafted for comfort and protection in hazardous, on-site conditions. Outfitted with reinforced toe and heel areas, these boots show their durability in the roughest environments. The Xpress Cool lining wicks away sweat and evaporates moisture, keeping feet cool and dry during an exhausting day. The Vibram outsole grips on to surfaces and enhances traction.
