Here are some pictures of Scott Reiniger in socks in the old movie, "Dawn of the Dead".
I think in one scene, he is barefoot, but he has the covers over his feet. I'm not sure, because in part of it, it looked like his heel sticking out from the covers, and if it was, it didn't look like he had any socks on. I know other than that, his barefeet aren't shown, but I might look at behind the scenes stuff later to see if there is anything.
