I'm 6ft 200lbs, I bought the big one. I used them for skiing, as a sock under winter pants and for dynamic movements (TRX, aerobics). They are great for skiing and I think they are great for running too. But in any activity where there's a lot of movement in the full-body position (burpees, mountaineering), they pull everywhere -- low at the waist so they're halfway in the back, tight at the ankle so they get stuck there. I have a similar style (which I actually wear now) with lots of stretch marks that doesn't have any of these issues and bought them to try another brand. Maybe the sizes are just a bit small from what I've read in other reviews, so maybe XL would have been better. But they fit so well on the waist and leg so I don't know. TL/DR - Great for running or similar, but not great for lots of full body movement.
