Look for socks with wicking material such as "Cool Max", though there are others. Some brands I like include BalGal, Wright, Wigums DeFeet. Check out oyur local running or bike shop. They will make a huge difference, once you get past the sticker shock ($8-$12 a pair at my local running shop). Check out bike and running races expos. At the last bike race I went to (as an observer) one of the tents had socks 6 pairs for $20 - theywere overstocks that were specially printed for specific events. Mine today are "Ride for the Cure" from Sept 11, 2004 from Aspen, and I was nowhere near, but I got the socks! Good luck.
