Lace-up Workhorse Boots combine a leather upper with a nitrile outsole, and can be used in temperatures as low as -74°F (-60°C). A unique molding process and an innovative multilayer inner boot system make sure that your feet stay warm and protected. Workhorse Boots are ideal for agriculture, chemical, construction, food processing, petrochemical, and utilities applications. Note: Boots run true to size, so go up one full size to allow for a good fit while wearing bulky socks. For example: If you normally wear a size 10, upsize to an 11.
