The updated F-XX II sports a sleeker profile, features the elite R500 stiff carbon fiber outsole for maximum power transfer and a sculpted footbed with a supportive heel that aids 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 is formed from a single piece of lightweight microfiber, with 6 air mesh inserts across the toe box and side panels to create an even airflow around the shoe and provide excellent ventilation for the entire foot. Two independent Atop 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.
