Sidi Socks by DeFeet Women's: The Aireator sports a mesh top that promotes quick drying and ventilation. The interior of the sock is made of Coolmax to wick the moisture away from your skin. The toe and heel are made of Cordura Nylon for extreme durability and abrasion resistance.

The super-stretchy "Stay-Fast" cuff never sags, even during high-impact events. Despite all these features, the sock remains thin and low-bulk - keeping your shoe fit the same as it would be without a sock.
