Castelli Fast Feet 4 TT

Castelli's Fast Feet 4 TT overshoes are designed for high speeds in time trials and races. Their streamlined design ensures smooth airflow around your shoes and ankles.

Fabrics and fit
The shoe part is made of a silicone-coated fabric that improves airflow around the shoes. Grooved Lycra material is applied around the ankles that helps detach airflow during movement. The race fit makes the overshoes tight around your shoes and ankles, and keeps them firmly in place while cycling at high speeds. The shoecovers are light and breathable, and suitable for outdoor temperatures between 10°C and 30°C. Their total weight is 66 grams.

Finish and details
The overshoes were developed within the Fast Feet project, which focuses on performance in time trials and road races. Flat polyurethane tapes at the top help keep them in place during exertion, and the smooth texture of the silicone coating supports a streamlined airflow around the shoes. The close-fitting construction supports a tight fit around your shoes and ankles. The lightweight design helps keep the overall weight low and makes the shoecovers comfortable to wear with high-intensity exercise and prolonged use.
