The Cylinder™ mountain bike shoe offers the comfort you'd expect from Giro with the quick adjustment provided by a Boa® dial. With a single dial and a set-andforget front strap, you can quickly get in your shoes and hit the trails. The Boa® L6 dial offers 1mm adjustment increments when tightening, and a macro-release function to get out of the shoe. The co-molded nylon and rubber lugged outsole provides high traction and durability.
