Shimano RC9PWR Wide SH-RC903PWR S-PHYRE

The Shimano RC9PWR Wide SH-RC903PWR S-PHYRE cycling shoes are a performance-focused road racing shoe engineered for riders who want a wide fit with race-oriented power transfer and secure closure. They build on Shimano’s S-PHYRE technology to deliver efficient pedaling, enhanced stability, and optimized fit for sprinting and high-cadence efforts.

These shoes feature a reinforced surround-wrapping upper with a tongue that works with a single BOA® Li2 metal dial and power boost guide plus a toe strap to reduce foot movement and promote consistent power delivery. The reinforced anti-twist heel cup helps stabilize the foot during aggressive efforts, while variable perforation and mesh in the upper improve breathability and accommodate a wider foot shape.

The ultra-stiff carbon sole and low stack height midsole are engineered to maximize power transfer from rider to pedal. The wide fit option provides additional room in the forefoot compared to standard RC903 models, making these shoes well suited for riders who find traditional race shoes too narrow. They are compatible with 3-bolt road cleats (sold separately).
