CASTELLI FAST FEET 2 SOCKS
For road rides or when it is not possible to wear the Fast Feet shoe covers, these socks save you watts.
There are many so-called “aerodynamic socks” models available on the market, but only the Castelli Fast Feet have actually been developed and tested to truly deserve this name. The few socks that have undergone tests were probably tested in static conditions, without movement since it is simpler. But a foot is always in motion, which is why we recreated a model capable of replicating the movement of the lower leg. We also carry out tests on cyclists in the wind tunnel to verify the results. With these socks you can save 2 watts at 50 km/hour.
KEY FEATURES OF CASTELLI FAST FEET 2 SOCKS:
- Castelli Fast Feet project, for riding even in hot conditions.
- The foot part is inspired by the Castelli Rosso Corsa sock for maximum comfort inside the shoe
- Polyurethane strip on the back to keep the sock perfectly in place
- The leg part is made of Lycra® with grooves designed to promote air flow
- Weight: 49 g.
- Temperature: 10°C - 30°C / 50°F - 86°F.
- Fit: Race.
