Castelli Fast Feet 2 TT Shoecover - Black

Unleash maximum speed and precision with these elite race-level shoecovers, designed to reduce drag and boost performance in time-trial and aero-road situations.

Why youll appreciate them

• Developed through detailed modelling of lower-leg aerodynamics, followed by cylinder and wind-tunnel testing to determine the optimal shape and surface.

• The foot section features a silicone-coated stretch fabric that smooths airflow over the shoe, reducing turbulence at high speeds.

• The ankle section is crafted from grooved Lycra that helps detach flow cleanly for enhanced aerodynamic efficiency.

• A flat polyurethane tape at the opening holds the cover securely in placeno slipping or bunching during hard efforts.

• Ultra-lightweight (~84 g per pair) and built for a temperature range of approximately 10 0C to 30 0C (50 0F to 86 0F) to suit high-effort rides in mild conditions.

Ideal for riders who

• Race time-trials or high-speed breakaway efforts where every watt counts and aero gain matters.

• Want a gear upgrade that offers refined performancesomething beyond standard overshoes.

• Prefer minimalist, performance-driven accessories that integrate seamlessly with their race kit.

What it means for your ride
When you pull these on, youre choosing precision-engineered coverage for your feet. Expect better tracking in fast efforts, smoother airflow around your lower legs, and a gear upgrade that ticks off one more performance box. The result: less drag, more speed, and confidence that your gear is working with younot against you.

Pro tip for use
Ensure your road shoes fit snugly and have a clean profile before fitting the covers. Pull on the cover so the silicone-coated section lays flat and the ankle Lycra grooves line up with the back of the shoe. Double-check the polyurethane tape sits secure at the cuff. For best results, ride briefly to verify fit and gliding performance before a time-sensitive event.
