I am the opposite really, in my personal experience I find running socks a waste of money to be honest. Maybe its my feet, or the socks I have bought, but I have not been impressed. First of all there were 1000 mile socks, which gave me worse blisters, then I got some Thor low socks, which are fine, but I don't really see anything special about them.
To be honest, I just normally wear some sports socks from Tesco, I find them just as good. I appreciate that everyone is different though, and some people must like them or there would not be such a market for them.
