Castelli Fast Feet 4 TT 2026 road cycling shoe covers
Competition and performance shoe covers
Notre avis
The Castelli Fast Feet 4 TT are the benchmark for performance in both time trials and road cycling, offering speed and performance.
Textile expert and former professional runner
These Castelli Fast Feet shoe covers are part of the Fast Feet project, developed to push the boundaries of aerodynamics in both time trials and road racing. Tested and approved at the highest level, they are used by the WorldTour team Soudal–Quick-Step and riders such as Paul Magnier and Tim Merlier. The silicone-coated fabric covering the shoe smooths the airflow, whilst the grooved Lycra ankle section helps to shed air to reduce drag. A flat polyurethane strap ensures a perfect fit at the top of the ankle, even at full speed.
