For over 60 years XTRATUF has been equipping commercial fishermen with Alaska proven footwear and boots. As fishing has evolved over the years so have fishermen's needs. We've continued to innovate and solve for how our boots can help our users stay safe, feel confident, and remain comfortable. Our iconic Legacy boot has been around since the late 50s and are being worn in more environments and for more reasons than ever before. We integrated modern technologies and design features into this classic and well proven style. The Legacy NXT features a brand new, form fitting last with expanded room in the calf and ankle, designed to fit our modern-day commercial fisherman. We have also added a dual density midsole for added underfoot cushioning for all day comfort. The NXT is 100% waterproof and is made with our signature triple dipping technique, which creates a seamless and flexible barrier that is highly resistant to many organic and inorganic acids, chemicals, and contaminants. Staying true to our Legacy DNA, the NXT comes with a non-marking, slip-resistant Chevron outsole that provides unparalleled traction on any surface in the most extreme conditions. 100% Waterproof Oil/Acid/Chemical Resistant Triple dipped latex neoprene rubber EVA midsole for added comfort Open cell foam insert for all day comfort SRA Slip resistant non-marking Chevron outsole ASTM F2892-18 M EH
