Offering all of the same upgraded features as the Legacy NXT, including form fitting last with expanded room in the calf and ankle, a dual density midsole for added underfoot cushioning for all day comfort, 100% waterproof and 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. While staying true to our Legacy DNA, the NXT ICE is also equipped with added insulation for greater warmth in cold conditions as well as the Glacier TrekTM Pro outsole which provides traction on soapy tile, glycerin on steel and wet ice for truly elite traction.
