I rarely use just wool socks. I go with light polypro socks as a base layer, and then knee-high wool socks as the over layer. That helps with the wicking.

If your feet are wet because of sweat, roll or spray anti-perspirant on your feet before you put the socks on.

If your feet are wet because of slushy and wet road conditions, wear booties over your cycling shoes. Your feet won't be 100% dry, but they will be drier than without the booties ... and the booties will block the wind which will make your feet feel warm, even if the are a little bit damp.

The temperatures you're riding in are just a bit cool ... you won't want to go with neoprene booties or anything too heavy or you will sweat up a storm. Go with light nylon booties.
