My gf finally convinced me to try my first pair of leggings, and I'm never going back. I run hot, so I thought I would overheat indoors in these bad boys, but no. They keep me warm outside, and I don't even notice them otherwise. Fit-wise, I'd say they're true to size. They run a little long, but I call that a feature, not a bug. They're also crazy soft, not scratchy at all.
