When you have a long, hard ride planned and require a sock with support, breathability, odor control, and impeccably detailed construction the best choice is the Castelli Premio 18 Sock. With a tall cuff for support and light compression to improve blood flow and stimulation, the Premio 18 covers all the facets of sock construction that enhance cycling performance while sustaining greater foot health throughout the ride. Employing a series of knitted structures functionally specific to key zones throughout the build, the design team at Castelli has delivered all of the key performance features, along with impressive climate control in and around the shoe and sock interface.

Whether it is the sleek forward metatarsal zone detail, the heel knit that ensures a durable fit without much stretch, a compressive midfoot support band, or the extra cushioning under the ball of the foot, the Premio 18 is expertly executed, and it all comes together in an asymmetrical construction that mirrors the shape of the foot. You can already feel it.
