Castelli Fast Feet TT Shoecover - SS22

Developed with Team Sky, the Fast Feet TT Shoecovers are all about cutting drag and so maximising power output during time trials and fast road races. Castelli tested the covers extensively, both via CFD analysis and in the wind tunnel, and this led the two-part design; a smooth silicone lower section gives a smooth profile across the foot, while the tall upper portion uses slim grooves to help detach airflow over the leg to decrease drag. The two surfaces work together to make these the ultimate choice when you want to gain vital time on rivals, particularly in time trials but also in road races.


  • Castelli's Fast Feet project – for time trials

  • Silicone-coated stretch fabric over the shoe smooths out airflow

Michael Excellent shoe cover for TT or track discipline. I was very surprised with the quality of the material - I was initially concerned that the material would be prone to tearing, but my fears were quickly assuaged when I put them on. Order a size up. They can also be put in the wash. I like them better than their predecessor.
