CASTELLI FAST FEET 4 SOCKS PINK
Description
CASTELLI FAST FEET 4
The science of speed applied to your feet: Fast Feet 4 socks are the result of rigorous dynamic testing to guarantee real aerodynamic gains where others only promise.
There are many so-called aerodynamic socks on the market, but Castelli Fast Feet 4 stands out due to its exhaustive development and testing. While most are tested statically, Castelli created a system that replicates leg movement and validated the results with real cyclists. The result is a sock capable of saving 2 watts at 50 km/h, making it an indispensable accessory for competition or for anyone looking to maximize every pedal stroke.
Rosso Corsa Technology and Lycra® Engineering
The lower part of the sock is based on the Rosso Corsa model, ensuring total comfort inside the shoes, even during maximum effort. In the upper part, Lycra® with technical ribbing works to release airflow, reducing drag. To ensure consistent performance, a polyurethane strip at the top prevents the sock from slipping down, maintaining its aerodynamic profile intact from the first to the last kilometer.
