The Legacy Boot has become a symbol of belonging - an icon of hard work and constant doing. The Legacy Boot is 100% waterproof, 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. This boot features a non-marking slip-resistant Chevron outsole that provides unparalleled traction in the most extreme conditions. 100% Waterproof Acid Chemical Resistant Approximately 5.15lbs Built-In Cushion Insoles with Arch Support Recommend half sizes order up Shaft Circumference is 15.5 inches and was taken from a size 9.
