Wear the SH-RC903 S-Phyre Road Shoes and ride with confidence. Designed for elite performance, these shoes combine lightweight materials, superior comfort, and unmatched power transmission to maximize every pedal stroke.
Maximum Power Transmission
Shimano’s S-Phyre range is engineered to deliver more performance per gram. The RC903 shoes are built to convert your effort into speed efficiently, letting you push harder and accelerate faster without wasting energy.
Accelerated Performance
The external curved heel cup stabilizes your foot, suppressing twist and roll for explosive acceleration. Redesigned structure, informed by foot movement studies and athlete feedback, ensures optimal stability even during high-tempo sprints.
