I have always worn the K. Bell no-show socks from Costco. These look really similar (aside from the lack of the "KB" logo near the toe), but the material is not as good. The Costco ones are cotton.
Anyways, I appreciate that these socks are comfortable and look minimalist, but overall they are cheap socks that don't last very long. One already got a hole so I threw it away. But they're less than $1 per sock, so I don't feel too bad.
