The Giro Men's Cylinder Mountain Bike Shoes offer the comfort you'd expect from Giro with the quick adjustment provided by a Boa® dial. With a single dial and a set-and-forget 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.
