The sleek uppers utilize a resilient polyurethane-laminated material combined over a comfortable mesh, resulting in reduced yield and providing long-lasting foot support where it’s needed most. The double BOA® Fit System, featuring the metallic Dual-Dial Li2 with premium bi-directional metallic dials, allows bi-directional and differentiated fit adjustments for the instep and forefoot areas, delivering the precise, locked-in feel that racers demand.

At the base, the R2 outsole’s engineered carbon fiber layup saves weight and delivers increased stiffness, with a stiffness index rating of 10, making this outsole the most responsive in the fizik range. A wide vent inlet and deep internal channeling provide cooling airflow, aiding in temperature regulation. The cleat positioning is set slightly further back compared to traditional settings to optimize pedaling efficiency and reduce knee compression—especially well-suited for very aggressive, forward aero positions.
