SHIMANO road bike shoe SH-RC903 S-Phyre 2023 | black
The SH-RC903 scored top marks in the RoadBIKE test (05/2025) and was awarded the test victory; it was also recommended as a best buy in RennRad magazine.
The top model in Shimano's S-Phyre line is an uncompromising competition shoe, tailor-made for you as a road racer. The 360° enclosing, one-piece construction sets new standards for fit, pedaling stability, stiffness and weight reduction. The shoe adapts to your foot and not the other way around. Reinforced and flexible mesh fabric is integrated in the front side area, which fits perfectly. The external heel counter stabilizes the foot during explosive movements, such as sprinting or high cadence. The footbed is removable and can be replaced with a customized one. In addition, arch pads are included to ensure that every foot shape gets an uncompromising fit. The BOA® Li2 lacing system with micro-adjustment and quick release also ensures a perfect fit. The very torsion-resistant carbon sole guarantees direct power transmission. A small heel under the heel supports you while running. And to ensure that you don't have to bathe in your own juices in the heat of the race, strategically placed ventilation openings provide sufficient airflow. The S-Phyre shoes are not only technically impressive, they also look great. The black lettering is definitely an eye-catcher and the aggressive shape of the offset heel area makes it clear to the competition that someone wants to win here.
Shimano DYNALAST
Thanks to the ergonomic DYNALAST last construction with a flat midsole, rounded heel and raised toe area, the shoe fits snugly and provides a glove-like fit.DYNALAST is optimized for maximum power transfer, efficiency and comfort. Extensive research by Shimano's R&D experts has resulted in a superior, anatomical last design with perfect toe camber.
