Shimano SH-RC901 S-Phyre Road Shoes Ultimate Power Transmision.

The first-generation S-Phyre RC9 shoe established a new benchmark for cycling shoe performance, weight, efficiency, stiffness, and comfort. Yet S-Phyre is about always seeking improvement — always innovating to be better. The second-generation S-Phyre RC9 is even lighter with enhanced hydrophobic materials to limit moisture retention, and features an improved heel cup and a revised pattern for improved fit and better transfer of power to the pedal. With S-Phyre innovation truly has no finish line.

3 Asymmetric Control

Asymmetric eyestay pattern prevents twisting of foot under high-power pedaling.

4 Unibody Construction

The elimination of the traditional lasting board reduces weight and lowers the stack height between the foot and pedal to better support the foot and maximizes power transfer and efficiency.

5 Low Stack Height

Low stack height carbon midsole helps stabilize foot during the downward pedaling stroke, maximizing power transfer.

6 Extended-range Cleat Adjustment

Extra 11 mm of cleat adjustment range.

7 External Heel Cup

Revised external curved heel cup construction minimizes foot twist and roll, stabilizes the heel, and holds the foot firmly in place.

Shimano Dynalast
Creating Pedalling Efficiency
The toe-spring section of a cycling shoe plays a key role in supporting efficient pedaling. Too high, and it causes increased tension in the plantar, calf, and hamstring muscles. Too low, and you get a bowlegged, inefficient pedaling form. Extensive research by Shimano's R&D experts has produced a superior shoe last design with an optimized toe-spring section that promotes a smoother, more energy-efficient upstroke. Built based on feedback from pro riders, Shimano Dynalast helps reduce energy loss on long rides, letting you keep more in the tank for that final sprint to the line.
