The all-new Ankle Deck Boot Sport isn't just a modification—it’s a total redesign of what a deck boot can be. Xtratuf has replaced traditional heavy materials with BioLite™. By reducing the weight by 30%, Xtratuf has significantly lowered leg fatigue, allowing you to stay on your feet longer and move faster. Whether you are bracing against the gunwale or moving across a slick deck, the BioLite™ foam provides long-lasting cushion life that won't pack out over time. Despite its lightweight feel, this boot makes no compromises on safety. It offers the exact same Pro-Grade slip-resistance and traction benefits of their classic full-rubber boots.Material Composition: Other Materials/Other Materials/Other Materials Upper Outer Material: Rubber Lining Material: Mesh Sole Material: BioLite™- High traction, non-marking  Water Resistance: 100% Waterproof Fastening: Pull On Estimated boot height 15cm/ 6" Estimated max circumference 32cm/ 12.6" Estimated weight 1.3kg
