Shimano S-Phyre SH-RX910 Gravel Shoes Men - White

Designed from the ground up with the help of Shimano pro gravel athletes, the RX910 delivers road-level power transfer, off-road capability, and all-day comfort.

Gravel racing is inherently contradictory. Riders need road-level power transfer for long stretches of pedaling efficiency, but also require some off-road traction for mud sections, river crossings, and technical terrain. Shimano’s new S-PHYRE RX910 gravel shoes resolve this contradiction, offering unmatched power transfer, walking stability, and all-day pedaling comfort in one streamlined package.

Revolutionary Pontoon Cleat System

At the heart of Shimano’s RX910 innovation is the new Pontoon Cleat System. This new feature includes a pair of modular, replaceable TPU contact blocks that dramatically improve the shoe-to-pedal contact point and optimize power transfer. The system enables a road-shoe-like pedaling interface while maintaining SPD compatibility and off-road functionality. 

Unlike traditional outsole-mounted contact blocks, the RX910's pontoons are part of the cleat interface itself. This means they move with your cleat position – vertically or laterally – for consistent support and efficiency, no matter how your cleats are set up. Plus, the pontoons are replaceable, allowing riders to start every race with a solid shoe-pedal interface.
