Designed to provide a superior riding experience, these shoes deliver an exceptional blend of efficient power transfer, advanced breathability, and a precision fit, now available in a wider last for those requiring extra volume. Whether you are tackling a challenging climb, sprinting for the finish line, or embarking on an all-day epic, the Sonic Plus Wide ensures your feet remain secure, comfortable, and perfectly ventilated from the first pedal stroke to the last.The heart of the Sonic Plus Wide's performance lies in its NRG Air Carbon Reinforced sole. This advanced platform achieves an impressive stiffness index of 8.0, ensuring that every watt of your power is transferred directly to the pedals for maximum efficiency and forward momentum. To combat heat buildup during intense efforts, the sole is integrated with the innovative AirFlow System, featuring five strategically placed vents that promote a constant stream of air, keeping your feet cool, dry, and comfortable even on the hottest days.Achieving the perfect fit is effortless thanks to the exclusive S.L.W. 2 (Speed Lace Winch) micrometric closure system. This state-of-the-art dial allows for millimeter-precise tightening, enabling you to customize the fit on the fly for unparalleled comfort and security. A single button offers a dual function: press for incremental, step-by-step loosening or lift to instantly release the shoe completely, making adjustments and removal quick and intuitive. This is complemented by an extra asymmetrical strap that helps distribute pressure evenly across the instep, eliminating hot spots and enhancing overall comfort.The upper is a masterpiece of design, featuring a Thermowelded Layer Construction. This innovative technique combines multiple layers without any overlapping material or traditional stitching, resulting in a feather-light, unibody upper that minimizes pressure points and provides a comfortable, sock-like fit. Generous mesh inserts are seamlessly integrated into the structure, further enhancing airflow and breathability. This model's defining feature is its Wide Fit design, which offers the same high-performance features with added volume, providing the ideal solution for riders with wider feet who often struggle with the constrictive feel of standard cycling shoes.For ultimate stability, the Integrated Heel System is built directly into the upper's structure. This design provides effective heel retention without the need for external elements, reducing weight and preventing any unwanted heel slip during the crucial upstroke of your pedaling motion. Inside, the Performance Advanced footbed offers excellent ergonomic support, further enhancing comfort and stability for long hours in the saddle.
