5'11" 180lbs in US Large. I've never tried more expensive brands but really like these. I try 1.5 to 2.5 Running hours a day and I feel a lot better wearing them, my only concern is that they tend to loosen up a bit mid-calf, so when I need compression for recovery and pain relief I often use a sleeve or a compression stocking to get much better results.Also I usually wear them 24/7.Another thing I would like to point out is that some colors have slightly different levels of compression despite being the same size.My two shades of blue fit noticeably looser than any other color.
