I tried them for the first time last night and at first he kept tearing it off but once he settled down for the evening, I managed to put it on and he left it there. At one stage he was so completely asleep, that I got the gaffa tape and secured it around his ankle to see if it would stay on through the night. This morning we woke to find it had worked so it looks like we'll just keep using the little socks for now. Although they are thin and will probably wear fairly quickly, I've got 8 socks in the pack I bought, and $80 will buy 20 packs so I think that is our solution for the time being. Here is a pic of Clarence with his new bootie/sock. I might try lining the inside of the sock with some more gaffa tape to protect the top of his foot when he walks.
Hope you all have a great weekend...
