Sidi GENIUS X Road Cycling Shoes White Size 40

The GENIUS X combines proven ergonomics with refined materials to deliver a road shoe that feels natural from the first kilometer. The premium microfiber upper adapts smoothly to the foot, offering support without stiffness overload.

Dual NUUN dials allow fast, precise adjustment on the go, while the High-Density Instep strap distributes pressure evenly for long-lasting comfort. A reinforced external heel cup keeps the foot stable under load, improving pedaling efficiency and control.

The R3CC composite carbon sole provides a balanced stiffness level, making the GENIUS X an excellent choice for endurance rides, daily training, and riders who appreciate comfort just as much as performance.
