The XTRATUF Sport Ankle Deck Boot delivers on a lighter boot (up to 30-percent lighter) than other 6-inch rubber boots in this category. The women’s Sport is constructed with a high-performance foam BIOLITE which is ultra-durable. The one-piece outsole is SRC non-marking and slip-resisting. This 100-percent waterproof boot delivers the comfort and agility of a sneaker with long cushion life and high energy return, all while offering the same traction benefits of a full rubber boot.
