Shimano S-Phyre SH-RC903 – Pro-Level Road Racing Shoes

The S-Phyre SH-RC903 is Shimano’s WorldTour-proven race shoe, built for riders who want every watt to reach the pedals. This black colourway gives a sleek, understated look that stays clean-looking through winter kilometres and wet-weather training.

Key Features:

• Precision Fit: Dual independent BOA Li2 micro-adjustment dials allow rapid, on-the-go tightening and fine-tuning for a secure, custom fit.
• Comfort & Breathability: Microfiber synthetic leather upper with surround-wrapping construction and function-specific zones provide superior comfort, support, and pedaling efficiency.
