Men’s 12”H Wellington features a waterproof leather upper with a long-lasting Cambrelle® II liner to keep feet cooler, drier, and more comfortable. Seam sealed waterproofing means boots are completely waterproof to keep feet dry in most types of wet conditions. Includes removable polyurethane airflow comfort orthotic insert, polyurethane midsole and outsole, and steel shank. Direct Attach construction is lightweight, flexible, and durable. The upper is placed in a mold and the liquid synthetic soling material is injected, which fuses, or directly attaches, the sole to the upper. This produces a tough, watertight bond. Nonmetallic design helps reduce the possibility of marking or scratching work surfaces. Note: This footwear is designed to provide secondary protection from incidental contact with live electrical circuits. It meets F2413-11 Section 5.5 requirements and is tested to resist the application of 18,000 volts at 60 Hz for 1 minute with no current flow in excess of 1 milliampere under dry conditions. It should not be worn in explosive or hazardous areas where conductive footwear is required.
