Running: The waistband on these is so firm that it just doesn't move at all. It didn't matter how much I was bouncing around, it stayed put.
Yoga: In yoga, however, the waistband kept wanting to roll down during a few poses, and I had a hard time making it stay in place.
Overall: I love these for running. They're very tight, which I like for running, and the mesh inserts let my legs get some air. I don't love them as much for yoga, but they still work pretty well.
