CASTELLI FAST FEET 3 SOCKS
There are many aerodynamic socks on the market. But Castelli's Fast Feet sock has the development and testing to support this claim. The few socks that have been tested were probably tested with a static test, not moving, because it’s easier. But a foot is always moving, so we created a support that replicates the movement of the lower leg. And we test on real cyclists to verify the results. This sock can save 2 watts at 50 km/h. The latest version has updated padding for greater comfort and aerodynamic gains.
CASTELLI FAST FEET 3 SOCKS KEY FEATURES:
- Developed and tested to deliver aerodynamic efficiency
- Can save 2 watts at 50 km/h
- Updated cuff for superior comfort and aerodynamic gains
