The DeFeet Women's Aireator 3in Sock is huge on both comfortable performance and unique style, but also comes in a package small enough to help you avoid those unsightly sock tans half-way up your leg. Crafted from a stretchy CoolMax blend, the Aireator makes the most of your ride by wicking sweat from your skin, boosting breathability, and flexing where you need it for miles of comfort. Then, mesh venting on the top of this sock further promotes both air circulation and durability for lasting reliable performance.
