5'11 180 lbs wearing US Large. Never tried the more expensive name brand ones but I like these a lot. I try to run for 1.5 - 2.5 hours a day and it's a lot easier when I am wearing these. My only gripe would be that they loosen quite a bit halfway down the shin so when I need compression for recovery and pain relief I often use a sleeve or compression sock for much better results. Other than that I usually wear these 24/7. Another thing I'd point out would be some of the colors seem to have slightly different levels of compression even when they are the same size. Both my blue ones fit noticeably looser than any of the other colors.
