Don't provide enough compression
Well, if you're looking for compression sleeves (emphasis on compression), these might not be for you.  I chose a size medium, even though based on the measurement chart, I should be wearing a large.  The material on these is pretty thin and does not seem to compress too much. I can only hope they contain copper as stated since I will continue to wear them to hopefully enjoy some pain relief from the copper in the material.  But these do not compress my calves to the point where I can work out in them and feel confident.  Even if I dropped down to the smallest size, the fabric is way too thin to actually compress.  For workouts, I swear by the Zensah compression sleeves for running or elliptical exercises.  They really grip the calves and keep them secure. No copper in them, but they do compress.
