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