The Castelli Fast Feet TT Shoe-Cover is designed for maximum aerodynamics in time trialling, within the limits of the UCI rules.
Castelli developed it through CFD analysis followed by extensive fabric and on-bike wind tunnel testing. The smooth silicone-coated foot portion smooths out the shape of the foot, while the grooved leg portion helps to detach the air as it flows around the leg. The shoe cover is cut high, reaching to the calf.
There's no reason not to wear it on the road, but its gains are maximized at TT speeds.
- Castelli's Fast Feet project – for time trials
- Developed with Team Sky for the fastest foot covering for time trialling
- Silicone-coated stretch fabric over the shoe smooths out airflow
- Engineered grooved Lycra® in the ankle portion helps detach airflow
- Flat polyurethane tape at the top to keep shoe-cover in place
