Bests & Worsts Reviews from Amazon

I thought all 7 pairs were 15-20mm regardless that 6 are Dr. Motion and 1 is Dr. Sham. I received 6 Dr. Motion at 8-15mm and 1 Dr. Sham at 15-20mm. Had I'd known 6 were at 8-15mm than I would not have purchased these. I have a history of blood clots, dvt's, and swollen ankle after a long day so I need a good compression on my leg. For reference, I'm 32yo, 5'4, 173lbs size 10/12 on a good day...so I'd like to think I'm an average American woman.
