No padding means no water or sweat absorption and super-fast dry time. Pro athletes rely on the AirEator sock for direct power transfer to their shoe and ultralight weight.

Comfortable and simple

  • Gender:Male
  • Familiarity:I've put it through the wringer

I love the simplicity of this socks and the amount of thickness. It is not too thick and does not move during cycling.


It's Defeet, duh.

    Huge fan of the socks. Cushion where you need it, minimalist elsewhere. Straightforward design and very comfortable.



      Great sock for warm weather. This sock breaths very well and looks great. I use them for cycling, hiking, and on cool weather climbing days as thin layer whilw wearing climbing shoes.


      buy these

        love these defeet. use them for cycling, speedskating, running, and dryland. super light weight, fast wicking, and quick dry. The fit is very good. I normally wear a size 10 running shoe and the large fits well. Recommend for any active individual who wants super performing socks.


        Super Sock

          I am addicted to these DeFeet socks - thin and light, they are my everyday choice all summer for biking, hiking and golf - light on the padding - if you need more padding look elsewhere.


          Keep cool

            I love these socks for riding in the summer. As long as you don't require any padding these are great for keeping your feet cool when it's hot.
