Unless it's cold out, I just wear just (a single pair of) liner socks. Quick drying, and depending on brand surprisingly durable.

Add a pair of wool socks if it's cold enough. Modify the above if blisters seem to be a problem ... injinji's if toe blisters, a light wool/synthetic mixture short oversock otherwise.
