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.
