Q: This seems to work very well. It brought down swelling on my wife's calf and ankle within hours. We particularly like that the sock covers most of the foot -- which many similar products do not -- because we needed this because of foot surgery. To the reviewers of many similar products who note that the zippers don't stay up: Try turning down the top inch or so of the stocking. That keeps the zipper in place.

A:
positive
