Get Up And Go

Enhance your performance with apparel designed to let you unleash the beast. The Castelli Go 15 Sock has the comfort and antibacterial properties you need to put the pedal to the metal, with durability and strength to let you ride mile after mile.

No more wasting time on cycling socks that just aren't worth the effort. An ultra-cozy merino wool blend delivers all you need without holding anything back. This fabric maintains warmth while also managing moisture for odorless post-ride beverages with friends. Nylon reinforcement in the heel and toe is perfect for your favorite shoe, keeping annoying holes and tears to a minimum.

Make your year with the Go 15, the sock designed for ultimate comfort on two wheels. A tall 15cm cuff rides high for a look you can boast to your friends, while multiple color options are sure to match your favorite cycling outfit.
