Been wearing Thorlo socks for 12+ years (probably more).  Usually bought the Basketball socks, as I prefer over the calf, for support.  Saw these, and now I have a new favorite.  If you hate socks that don't stay up, due to stretched elastic......then these are for you.  Actually, all the Thorlo socks last a long time.  It's those department store socks that refuse to stay up, after a half dozen washings.  All my socks are Thorlo.
