Doesn't quite work for me...
I wear an 81/2 shoe and I ordered a small/med.  The part of the sock that goes up my leg is not long enough to stay up on my calf all night.  It's great when I first put it on, but by morning it's worked its way down to my ankle.  If I try to tighten it enough so it doesn't come down it's very uncomfortable and feels like it's cutting the circulation off in my leg.  Maybe it would work better if I had ordered a large/X-large.
