The men's Legacy NXT features a new, form-fitting last with expanded room in the calf and ankle. Also included is a dual-density midsole for added underfoot cushioning for all day comfort. The NXT is made with a signature triple dipping technique, which creates a seamless and flexible barrier that is completely waterproof and that is resisting to organic and inorganic acids, chemicals, and contaminants. This 15-inch pull-on rubber boot also has a reinforced ankle and heel area for increased durability. Staying true to the XTRATUF Legacy hallmarks, the NXT has a non-marking, slip-resisting SRA-rated Chevron outsole that provides excellent traction on multiple surfaces in a variety of conditions.
