Looking for a tough, durable and comfortable work boot? Keen has you covered with their Men's Waterproof Puncture Resistant Met Guard Comp Toe 6" Work Boot. This boot is ASTM/ANSI I75 and C75 approved and features a full-grain waterproof Barnyard resistant SPR leather upper. The breathable membrane helps to keep your feet dry and comfortable all day long, while the lightweight Poron XRD metatarsal guard protects against impact. The carbon-fiber toes are 15% lighter than steel and offer an unobtrusive fit, while the mesh and moisture-wicking textile lining provides next-level comfort. The Keen Luftcell air-infused PU midsole provides weightless comfort, and the 3/4 Goodyear welt construction ensures durability. Plus, the contoured heel lock is anatomically shaped to reduce heel slip. With all of these features, Keen has created a boot that will help you get the job done right.
