The Shimano SH-RC703 Large are road cycling shoes designed for riders who want near-professional performance without compromising on fit. Sitting at Ultegra level within Shimano's lineup, they carry the same core technologies developed for the top-tier S-PHYRE range.
The hollow carbon fibre midsole, rated 10 out of 12 on Shimano's stiffness index, channels your pedalling power efficiently with every stroke. SHIMANO DYNALAST technology further refines the biomechanics of the pedal stroke, encouraging a smoother and more natural motion throughout your ride.
The upper is made from breathable synthetic leather with strategic perforations, bonded seamlessly to the midsole in an wraparound construction that holds the foot securely without creating pressure points. The dual BOA® L6Z closure system, paired with cross-lace Power Zone lace guides at the forefoot, delivers even and finely tuned tension across the whole foot.
The wide (large) version offers roughly 9–10 mm of additional forefoot circumference compared to the standard fit — a meaningful difference for riders with broader feet or those who simply prefer more room during long efforts. Full compatibility with SPD-SL 3-bolt cleats means these shoes work seamlessly with virtually any road pedal system.
