Hmm, I don't have any golf socks per say, but I do have some "sport socks," and I notice that they are pretty thin, and that the material is supposed to be wicking to keep your feet dry. I do notice that they tend to stick to certain types of rugs when walking around in them.
I am not sure about golf socks in particular though. I have never owned a pair of golf socks or any FJ socks, but I plan to try them in the future. If they are FJ socks, they could just as well be pretty up to date with minimal changes now if they are not more than a few years old.
