The Shimano RC903 S-Phyre Road Cycling Shoes deliver WorldTour-level performance with a lighter weight and improved fit compared to their predecessor. The upper utilizes flexible microfibre synthetic leather with micro-perforations to reduce hotspots and enhance ventilation, while the lower tongue features perforated mesh for cooling on hot days. Two BOA Li2 dials secure each shoe, allowing quick and easy mid-ride micro-adjustments.

The carbon fibre sole is exceptionally stiff, and the seamless midsole reduces stack height for excellent power transfer. An anti-twist heel cup holds the foot in place during hard efforts.
