The Aireator is the sock that started DeFeet, designed in 1992 as the first cycling sock with an open mesh weave instep for breathability and moisture wicking. 
The lightweight and durable Aireator is available in a single and a double cuff, with the double cuff providing additional compression in the ankle zone to prevent slipping. 
This sock has a close fit in performance cycling shoes, and a recycled performance polyester locally manufactured from recycled plastic bottles, reducing landfill waste.

The thin profile Aireator features an open mesh weave over the foot top, making these lightweight socks ideal for all forms of cycling and everyday adventure. Breathable, moisture wicking, and durable.
