I like these capris, but I can't imagine running in them. They're soft, and very comfortable. But I feel like they would make you sweat a lot. I am 5'4' and 116lbs, I ordered size small, and the waist fits well, but there pretty flowy everywhere else. I'm not mad about that. I love Russell brand, however I feel like these are more for lounging, than athletic. I will keep them and wear them on the go, or just a lazy day. I will not work out in them though. Good capris for the price. :)
