Made in the USA, these work boots build upon classic SuperSole performance to provide even more durability and comfort in the heaviest-duty work environments. They feature a low-density inner sole that provides cushioned comfort, while the tough rubber outer sole delivers best-in-class slip resistance and protection against chemicals, heat and abrasion. Combined with a steel safety toe, built-in electrical hazard protection and full-grain oiled and waxed leather upper that extends high up the calf, these boots are ideal for work in the oil and gas, construction, manufacturing and railroad industries.
