Stable and Powerful
Borrowing its design and technology from pro-level racing shoes, the RC503 utilizes power-zone lacing over the toe box and a carbon-reinforced nylon midsole for impressive stiffness, rigidity, and foot hold. The lower stack height helps to create a more stable pedaling platform, reducing foot movement and increasing power transfer from rider to road.


Ultimate Comfort
Constructed using a seamless pattern of performance materials, the laminated mesh upper securely wraps your foot and reduces unwanted gaps or pressure points. Supple synthetic leather and lightweight TPU mesh keep you ventilated and cool, while the BOA L6C dial allows you to make adjustments quickly and easily even while riding.
