This 11” waterproof nano comp toe boot is built with new high-tech features designed to keep you comfortable long after the workday is done. The NiTread features the new N2Gen™ technology in the insole which includes nitrogen encapsulated impact zones in the midsole that absorb shock, then redistribute the energy to reduce foot fatigue throughout the day while helping to extend the life of your boots. It also includes a Removable Ortholite® Insert, an oil-and slip-resisting rubber outsole to keep you steady on your feet all day, and our nano-composite toe – our strongest, most lightweight safety toe that’s designed with added toe room. This boot is electrical hazard rated and features a non-metallic shank. Safety features meet ASTM F2413 safety footwear standards.
