The DeFeet "Flying D" logo on these socks is the badge worn by all of our top athletes.. This model carries the 5" DOUBLE CUFF which creates a slightly thicker, burlier and even more durable arrangement
Aireator is the airflow design sock that changed how modern endurance socks are made. With its trademark venting mesh weave foot, durable StayFast cuff and plated heel & toe that wear like iron, the Aireator guarantees long-lasting performance. Made with CoolMax® EcoMade™, the fiber that is made from recycled resources.
The original Aireator® is built by cyclists for cyclists. Born in 1992, the Aireator® is the first product that launched DeFeet® and today its still the workhorse of the DeFeet® line. The Aireator® is the undisputed, original airflow design and first sock with a open mesh-weave instep (hence the name). It was also the first design sock that was customized with a logo, colors, and text. Before the Aireator®, that simply wasn't done. It has been worn to victory in nearly every International cycle race. The Aireator® still leads in lightweight, durability, moisture wicking and air permeability.
