you know, this is a dark age based game.
At the dark age people did not have socks, they luckily managed to get shoes. when one wanted to soft the feeling at his feet he would simply wear long pants and stick them down into his boots. Socks are pretty much something used only in now-days
But in Oblivion they had those legging like garments on men. So there should be socks, just to be fair.
Just a question: what would the Argonians wear? I mean they have those talons thing at their feet/paw thing.
