This is my seventh pair of Thorlo socks.  I use the newer ones for running/working out and the older ones I wear for work.  I know many people complain about the high cost of these socks - the ones I use for work are over ten years old and still good.  I have dealt with plantar fascitis in the past and I like the cushioning in these socks.  They are thick and that should be taken in consideration with the shoes you're wearing.  I also like that they seem to keep my feet dry.
