Product details
The fast and efficient shoe with proven robustness and grip, designed for the most demanding uses. Easy adjustment and a clear design make it particularly straightforward and ready to use immediately.
Make your ride possible. The sole maximizes comfort on the bike, aerodynamic, lightweight, and with a balanced ratio of stiffness and flexibility (stiffness index 5), thanks to nylon and carbon fibers.
Fits like a Sidi. No secret: since 1960, we have been perfecting the fit of cycling shoes. The Fast 2 is the result of over 60 years of relentless innovation and experience.
Fast, adaptive closure. Quick, error-free, and precise, with a unique micrometric adjustment.
Gentle to the touch. A soft, lightweight upper that adapts to the shape of the foot for outstanding comfort.
Locked heel. Our heel stabilization is hidden inside but always there to keep the foot secure throughout the ride.
Made to last. It’s a Sidi. Great products stand the test of time. That’s why we choose the best materials and make all parts interchangeable, so you can keep your favorite shoe for as long as you want.
