Assuming you're looking for white socks, I would recommend going to Gordmans (Or equivalent) and just purchase some name brand socks at discounted prices.
They do cost a bit more, and will last a bit longer, but they all get dirty the same. This is why I purchase cheap no show socks from Wal-Mart and replace them accordingly.
As AStar recommends, so do I. You may end up not liking the thicker socks some brands offer, as they feel like more of a shoe than a sock, and don't ventilate as well.
My advice: Just buy cheap socks and replace them often.
