These aren't work horse socks, but stand up to the everyday grind of a normal work life. They are thin throughout, but tight in the arch and cushioned on the toe and heal. They breathe great and don't seem to have any problems with durability yet. The design on the sock is cool, yet subtle.
For reference, I am a size 10.5-11 shoe size.

Great wool socks. Light weight, but still a little thicker than I'm used to with running socks. The quality is great. I would recommend.

There socks are awesome! Great fit and very comfortable; I ordered three additional pairs after testing them out. All-around great running sock.

Take these on a run, it was like wearing nothing, so light. Kept my feet cool.
