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. This boot meets ASTM F2892 safety footwear standards. It also features a Removable Ortholite Insert and an oil-and slip-resisting rubber outsole to keep you steady on your feet all day.
