All boots within the Legacy collection are 100% waterproof. Each boot is made with our signature triple dipping technique, which creates a seamless barrier that is highly resistant to many organic and inorganic acids, chemicals and contaminants. Our latex neoprene is ozone resistant, and is softer, lighter, and far more pliable than ordinary rubber. Cushioned insoles with arch support help fight fatigue and stress on the legs and back. All XTRATUF® Legacy boots come with a non-marking, slip-resistant Chevron outsole that provides unparalleled traction on any surface in the most extreme conditions. Insulated styles come with built-in Polymeric Foam insulation. The insulation package will keep your feet warm even when it is -10°F.
