Shimano RC9 SH-RC903 S-PHYRE

The Shimano RC9 SH-RC903 S-PHYRE is Shimano’s flagship road cycling shoe engineered for elite performance, precision power transfer, and optimized fit across long distance and high-intensity riding. It uses a stiff, full carbon sole and performance-oriented upper design to support efficient pedaling, stable foot placement, and comfort during long efforts.

The RC9 integrates an asymmetric BOA® Li2 dual dial closure system for precise micro-adjustment of tension across the foot, combined with strategically placed reinforcements and breathable materials to balance rigidity with comfort and ventilation. The shoe’s construction is optimized to reduce hotspots and unwanted foot movement under load, while the low-profile carbon sole maximizes power transfer to the pedal.

Designed with Shimano’s Dynalast geometry and performance-oriented internal shaping, the RC9 accommodates a high-force pedaling style and supports riders seeking race-level responsiveness without sacrificing long-ride comfort. The shoe is compatible with standard 3-bolt road cleat systems.
