The Uppers are crafted from genuine neoprene and rubber, providing 100% waterproof protection. The innovative neoprene-bootie construction and breathable Airmesh Lining make these shoes perfect for any weather conditions. With a storm-proof natural-rubber shell and reinforced toe and heel, you can trust in the durability of these shoes. The Dureva outsole is ultra lightweight and has a grippy Starliner tread, giving you speed and agility on any terrain. The premium fully-moulded removable PU sockliner provides all-day comfort and durability. Built on a sneaker platform and featuring a contoured internal nylon shank, these shoes also offer excellent arch support. The 4-way stretch topline openings make for easy on/off convenience, while the soap and water clean-up makes maintenance a breeze. These shoes fit standard athletic shoe sizes and are best paired with a thin running shoe or no-show sock. Plus, they're fully buoyant, even when completely submerged!
