The Castelli Womens Sfida 13 Socks deliver all it claims to be and more. Constructed from a merino wool blend that offer excellent warmth on the coldest of days while being highly breathable, your feet remain warm and dry throughout the ride.

Add in an additional layer of thickness at the sole of the sock protecting against the wind chill that enters from underneath the shoes. Cycling socks these days are also equally about the design, stylish and functional.
