The Cylinder II mountain bike shoe offers comfortable wear with the simplicity and precision of a BOA closure system. With a single dial and a set-and-forget Velcro strap at the forefoot, you can slip on your shoes in no time and hit the trail. The BOA L6 dial provides 1 mm adjustment increments for tightening and a macro-release function for easy removal. The upper construction offers excellent support and breathability, while our co-molded nylon outsole with a rubber tread provides remarkable durability and reliable traction on nearly any surface.
