Castelli Fast Feet 4 - Socks
Product information "Fast Feet 4 - Socks"
Many socks call themselves aero, but the Castelli Fast Feet 4 sock has the development and test results to prove that it lives up to that claim. Most aero socks are probably tested in a static state because it's easier - but Castelli has developed a device that mimics the movement of the lower leg, and also conducted tests with real cyclists to verify the results.
This sock can save you around 2 watts at 50 km/h. The latest version features an updated cuff fit for even more comfort and additional aerodynamic benefits.
