Giro Alpineduro Winter Shoes. The Giro Alpineduro isn't just a biking shoe. It's a rugged, hiking shoe that happens to clip into a bike pedal. With a grippy, Vibram rubber outsole, PrimaLoft insulation, and a clip in, pedal ready nylon shank that doesn't sacrifice walking comfort or grip, the Alpineduro is the all weather, all terrain adventurer. There's even an optional cleat cover for flat pedal use and a flexible forefoot zone for walking. Perfect for the Mountain Bike rider who enjoys hiking as well as biking or the everyday commuter, the Alpineduro is the perfect shoe for riding in the winter. The breathable microfiber and waterproof liner will keep your feet dry and comfortable despite the elements, while the PrimaLoft insulation keeps them warm. The rubber tow and heel reinforcement will protect against injury, as will the reflective details that will be seen in low light situations. The brushed EVA footbed with X Static anti microbial treatment will even help keep your feet clean regardless of what you step in.
