Castelli Atelier Socks

Castelli Atelier Socks. The Castelli Atelier Socks are crafted from synthetic fabric, for increased stretch and durability, and Merino wool, a natural material, which is warm and breathable, making it ideal for mild to cold weather. These socks feature a 5.11 13cm tall cuff, which covers the base of the calf, to ensure there's no exposed skin between the shoe and pant cuff, keeping feet and ankles cozy on cool, brisk days.
