Shimano SH-RC910 S-PHYRE Road Bike Shoes

The Shimano S-PHYRE SH-RC910 is Shimano’s flagship road race shoe, built for racers and riders who want maximum efficiency. It sits on Shimano’s new SPD-SLR pedal platform, which has the lowest stack height Shimano has ever made, while keeping a wide range of cleat adjustment.

The redesigned Hollow Core carbon sole has a stiffness index of 12 for direct, lossless power transfer. A seamless midsole drops stack height by 0.5 mm compared with the previous S-PHYRE. Paired with the Dura-Ace PD-R9300 pedals, the total stack height reduction is 2.8 mm versus the previous generation. Your foot sits closer to the pedal axle for a more stable, connected feel through every pedal stroke.

The new SHIMANO DYNALAST 2.0 last gives more room in the toe box and reduces carbon sole fatigue during long, intense races. A surround-wrap upper in lightweight Japanese microfiber holds the foot snugly. New perforations improve breathability. Two BOA Li2F dials with a new lacing pattern give an even, secure fit you can fine-tune on the fly.
