Now I use a large plastic Easter Egg that I've taped so it doesn't open easily. I use it rarely, but have a pair of Ragg socks, very thick wool, that I wore back packing on my honeymoon. All other pairs have been tossed, totally worn out, but this is still wearable for house shoes. I think I'll darn them and then sew them to a thick piece of felt for soles.
