The Carbide R II is an XC shoe with the comfortable, supportive fit found in Giro's premium shoes. They added a nylon and rubber co-molded outsole for impressive durability, grip, and traction in rocks and mud. While they were at it, they redesigned the upper to combine supple synthetic fiber with mesh panels for increased breathability and lighter weight. Three wide straps allow easy fit adjustments, and a supportive EVA footbed enhances comfort. A stout injected nylon sole helps transfer power to the pedals instantly, enhancing your connection to the bike.
