Fast Feet 4 TT Shoe Covers

Castelli Fast Feet 4 TT Shoe Covers

The Castelli Fast Feet 4 TT Overshoes are designed for cyclists who demand every possible aerodynamic advantage in time trials or road racing. Developed as part of Castelli’s Fast Feet project, these shoe covers have been extensively tested to deliver the fastest airflow over your feet, giving you measurable gains without compromising comfort or fit.

Crafted with silicone-coated fabric over the shoe, the Fast Feet 4 smooths airflow for reduced drag, while engineered grooved Lycra® on the ankle helps detach airflow efficiently. A flat polyurethane tape at the top ensures the cover stays securely in place throughout your ride. Lightweight, aerodynamic, and performance-focused, these shoe covers are essential for any rider looking to maximise speed and efficiency on race day.
