Castelli Free 9 Sock

Castelli Free 9 Sock

The Castelli Free 9 sock is constructed of Meryl Skinlife antibacterial yarns that work like magic to manage moisture in order to keep your pistons cool, comfortable, and kicking out the power. Diaphanous mesh is woven into the top of the foot and runs up the ankle to serve as a giant vent that circulates air. The Free 9 features a support band around the middle that allows the sock to form to your foot, ensuring it doesn’t bunch up in the shoe and providing support the arch of your foot, while the reinforced cuff holds the sock in place.
