Race-Proven Performance Road Shoe Built for riders who demand elite-level performance without compromise, the all-new RC810 brings flagship-inspired technology to Shimano’s premium racing lineup. The shoes borrow key innovations from the S-PHYRE RC910, including SHIMANO DYNALAST 2.0, dual BOA® Li2F dials, and an optimized low-stack carbon sole. The RC810 delivers exceptional pedaling efficiency, precise fit, and confident stability for every race and training ride. FEATURES: Efficient Power Transfer: Carbon sole with low stack height design maximizes pedaling efficiency and delivers a direct connection to the pedals. Performance Fit: Updated SHIMANO DYNALAST 2.0 provides a wider forefoot, reduced toe spring, and a more natural fit for sustained comfort. Precision BOA® Adjustments: Dual BOA® Li2F dials provide fast, micro-adjustments for an even wrap across the foot. Confident Stability: Integrated heel cup stabilizer structure helps secure the foot during hard accelerations and high-power efforts. Expanded SPD-SLR Adjustability: New cleat adjustment range with easy-to-read alignment markings makes dialing in your ideal pedaling position easier than ever. Premium Race Comfort: Lightweight synthetic leather upper offers breathable comfort while carrying the sleek styling and performance DNA of SHIMANO’s flagship S-PHYRE shoes.
