What Our Gearhead® Experts Are Saying:
"The Castelli Logo 18 Merino Sock fits so close to a summer sock inside the shoe that I almost forgot I was wearing a cold-weather option. The two-tone colorway looks sharp on the bike, and the merino blend kept my feet comfortable through a long fall ride without any of the bulk I usually have to deal with in cooler temps."
The Castelli Logo 18 Merino Sock delivers the same thin, close fit that makes a summer sock feel right in the shoe, but with the natural warmth of a merino wool blend underneath it all. The bold two-tone colorway makes a statement on the bike, while the 18cm cuff keeps coverage consistent with tights or leg warmers. Form and function land in exactly the right place.
