Product Details: A playboater's go-to bootie, the lightweight NRS Freestyle Wetshoe is crazy flexible, perfect for fitting into tight boats. Plus, a naturally shaped toe box and high-rise design provide additional comfort and protection for all-day boating. A sustainable alternative to traditional neoprene, petroleum-free Terraprene neoprene is made from limestone and recycled tires. Constructed with 3 mm thick neoprene upper for maximum warmth with a 3 mm neoprene insole for added comfort. Stretchy rubber support bands improve lateral stability while a 1.5 mm textured rubber outsole provides protection and optimal grip. Cush graphene-infused interior provides thermal-conductive properties for more warmth while also reducing water retention. The HydroCuff™ hugs the ankle tight to prevent excess water from dripping in. Reinforced at the toe and heel for long-lasting durability. Features an ankle pull tab to help slip the bootie on and off.
