I purchased these pants when I started to run a lot and now they are my go-to pants for all gym activities. Getting into them is like getting into Spanx, but once they are on, they fit like a second skin and, incidentally, make your rear look fantastic. I do feel like the exoskeleton support helps my knees when running and I appreciate the simple black-on-black design aesthetic. I have already recommended these to several friends and explained their benefits. My husband bought me another pair as a gift since he knew I loved them so much!
