Riders who currently wear a Standard fit can expect more room in the toe area, while those who previously sized up for extra width or toe room may prefer going down by ½ size for a more precise fit. The Shimano RC910 Wide Fit delivers flagship S-PHYRE performance with a more accommodating fit for riders who need extra room through the forefoot. With Shimano’s lowest stack height, carbon hollow core sole and precision BOA® closure, it is engineered for maximum pedaling efficiency, stability and race-ready comfort.
