The Shimano SH-RC703 is a performance-focused road cycling shoe built with race-ready technology derived from Shimano’s flagship S-PHYRE line. Designed for efficient power transfer, secure fit, and all-day riding comfort, the RC703 combines a lightweight construction with a stiff, low-stack carbon midsole for stable and responsive pedaling.
A high-rigidity hollow carbon midsole provides efficient power transfer while ventilation openings beneath the toes and heel help move air and drain water. The breathable synthetic leather upper uses Shimano’s surround-wrapping construction to reduce overlap and create a close, supportive fit.
Dual BOA® L6 type Z dials provide precise fit adjustment, while the low-profile crossover lacing pattern securely holds the forefoot. Shimano DYNALAST technology is designed to promote smoother pedaling and efficient power transfer.
