Product Details Despite the high-top design for added support and protection, the NRS Men&';s Paddle Wetshoe maintains a low profile for fitting into tight boats. Thick neoprene coupled with a soft interior lining provides maximum insulation, while a hardy rubber sole protects your feet from rocks. A sustainable alternative to traditional neoprene, petroleum-free Terraprene neoprene is made from limestone and recycled tires. Construction combines a 3 mm thick neoprene upper with titanium adhesive throughout for increased warmth. A 3 mm thick high-traction sole, paired with a 5 mm neoprene insole and 2 mm plastic shim provides maximum protection. Cush graphene-infused interior provides thermal-conductive properties for more warmth while also reducing water retention. A hook-and-loop webbing strap across the top of the foot adjusts for a customized fit. Designed with a naturally shaped toe box for all-day comfort. The gusset-backed YKKA(R) entry zipper opens wide, letting you easily slip the Paddle Shoe on and off, whether barefoot or over socks. Also features a webbing pull tab to aid in donning. Reinforced at the toe and heel for long-lasting durability. Spaces: Weight: 1.7 lbs.
