For when you're working in hot weather conditions, the Muck Boot Men's Chore Cool Mid Work Boots are a great addition to your work uniform. Rugged Spandura® uppers are tear resistant, and the Vibram® outsoles keep your feet stable on almost any surface. As your feet start to sweat, the XpressCool™ linings absorb the moisture for a cool feel, while the 4-millimeter CR Flex-foam insoles provide a dry and warm feel for your feet.
