To the OP. wearing that day's socks to bed can make your feet cold due to any dampness or perspiration on them. From scouts I was always taught to put on a clean dry pair of sleeping socks to stay warm. Thus, when I back pack I have one pair of wool socks that I only sleep in.
Generally, I do my sock change at night when going to bed. Unshoe, take off the day's pair, let my feet air out and dry a big, then on goes the new pair. That pair gets worn the next day, and the next night, repeat.

I usually don't have wool socks (I just don't own any) but my heavy hiking socks have done me quite well so far using this method.
