These engineer style boots by Chippewa are made to handle even the toughest jobs. The steel safety toe cap meets or exceeds ASTM F2413-05 standards for impact and compression, keeping your feet safe on the job. The leather lining and the Texon insole work together to keep your feet comfortable under all conditions. The black Chippewa #475 Nitrile sole has a flat surface for better surface contact, and is made with a heavy duty nitrile/rubber compound. This sole is very durable and can be used in just about any application. From day one, Chippewa's mission was to manufacture the finest boots and shoes in the United States. Over 100 years later, Chippewa is still standing up to their mission.
