When every watt matters and every adjustment counts, the all-new S-PHYRE SH-RC910 shoe represents the next evolution of SHIMANO’s flagship road racing shoe. Engineered as a complete pedaling system alongside the new SPD-SLR pedal platform, the shoe is designed for the world’s fastest riders and refined through extensive WorldTour feedback. The S-PHYRE RC910 delivers exceptional power transfer, an even more precise fit, and the lowest stack height Shimano has ever produced.

Sizing Note

Riders who currently wear a Standard fit can expect a roomier toe box, while those who previously sized up for extra width or toe room may prefer to size down by ½ size for a more precise fit. The new SHIMANO DYNALAST 2.0 Wide fit is noticeably roomier than both the previous DYNALAST Wide and Standard fits, offering increased width and a larger toe box. Women riders and anyone who prefers a snugger, performance-oriented fit may find the Narrow option provides the best fit.
