Castelli Free 9 Socks White/Red
The Castelli Free 9 Sock. Our Rosso Corsa sock was the basis for the free 9 sock, but we’ve added a new mesh construction to the cuff to make it a bit cooler for summer. The graphics look great with any Castelli product, but they were specifically designed to match the new free jersey and free bibshort.
