I don't mind running around in them.... I just threw a pair of shorts on over the top to go to the store yesterday, but I doubt I could wear them to bed. They would just be too warm. It hardly ever gets super hot here, so I'm not sure how hot will be too hot to tolerate having them on.

I'd say I've worn mine for 5 or 6 hours after my ride each time I've used them. I think they make a good difference in the way my legs feel the next day. I'm taking them to a race next week, where hopefully they also make a performance difference too.
