Never worn outside. I wore these indoors at a facility, but I'm selling them now that I've left. They have cushioning but aren't too soft, and they're lightweight and easy to move in. Perfect for aerobic exercise, running, and gym training. Nobody else has worn these, so you won't have to worry about anyone else wearing the same ones.
