I am happy to report my legs feel great this morning. Usually, running causes me great pain, even with stretching. One of the reasons I stopped (besides my back) is that my legs were always so sore, I didn't feel like riding. I am going out for a quick 18 mile ride before we get on the plane for Spain.
I didn't sleep in them, but did wear them for about 4 hours. I will be putting the calf socks on before I dress for the trip, later.
