The wedge-soled Cincinnati work boot is designed with a full-grain, waterproof barnyard-resistant leather upper to resist the damaging effects of oleic acid, urea, sodium chloride and ammonium hydroxide. It has a KEEN Luftcell air-infused polyurethane midsole. Inside the boot, a removable, dual-density polymer foot bed with an aerated pillow-top cushioning adds to the overall comfort fit, while safety comes from the left and right asymmetrical, nonmetallic carbon-fiber toes that are 15% lighter than steel. Other features: The KEEN.Dry waterproof, breathable membrane; an electrical hazard-rated rubber outsole; and a Cleansport NXT lining that provides odor protection free of chemicals and perfumes.
