The updated F-XX sports a sleeker profile, a more rigid carbon outsole and is molded using a lighter microfiber upper. The F-XX features the elite R500 stiff carbon fiber outsole for maximum power transfer and a sculpted footbed and supportive heel that aid to increase blood Flow, reduce hot spots and ensure that every power watt goes directly into your pedal for maximum performance output.

The seamless upper mold is formed from a single piece of lightweight microfiber, with air mesh inserts across the toe box to create an even airflow around the shoe and provide excellent ventilation for the entire foot.

Two independent adjustable retention dials optimize closure in each of the critical foot zones. The upper dial secures the arch and forefoot, while the lower dial locks the ankle /heel ensuring a snug fit and zero heel movement.

A new one piece toe guard and heel guard have been designed to further reduce weight, increase airflow and improve off the bike stability.
