The Giro Factor ACC shoe delivers class-leading stiffness with the all-day comfort needed for long rides and maximum effort. The breathable Evofiber upper molds to the shape of your foot for a superb fit and the two-way micro-adjustment of the low-profile buckle allows for precise adjustment on the fly. At only 6.5mm thick, the light weight Easton EC90 unidirectional carbon fiber outsole is engineered to provide optimal power transfer to the pedal and transmits your full efforts into forward motion. SuperNatural footbed (with arch inserts) allows you to tune the level of arch support, and the X-Static anti-microbial fiber enhances efficiency and comfort. 3-hole cleat compatible. 240 grams.
