The Arch Hybrid features Tretorn's classic stylish Scandinavian design without compromising on function. A perfect shoe for cold and rainy days without sacrificing your personal style. The Arch Hybrid is lightweight, warm and waterproof with extreme comfort thanks to its natural rubber and neoprene construction, along with a warming pile fleece winter lining. Its discreet back zipper makes it easy to put on and take off. The Arch Hybrid runs small, we recommend going up a size.
