Girls, When wearing fishnets, should you wear socks as well?

Right, this ones for the girls. My girlfriend LOVES fishnet tights. She wears them loads with a skirt or a pair of denim shorts. What I questioned her about though, was why she doesn't wear socks with them. She says they are like normal tights, they do a pretty good job of stopping her feet rubbing in Converse, boots, vans etc. But surely her feet / tootsies get quite sweaty as I think it's basically like going barefoot? They don't seem to ever smell that bad though which I guess is lucky!
Settle an arguent people, should she had socks on, or are fishnets comfortable enough to wear without them in boots / converse / vans etc?
