I own two pairs of these socks that I wear to work as a nurse on a busy med-surg floor. I realized recently that the actual mmHg of these are lower than what I probably need. That being said, for what they are, they do a great job. I like the thicker material of the sock and the graduated compression. The best part of these socks which I cannot find elsewhere in the 20-30 mmHg range or thigh-highs, is the odor control from the silver drysat. Regular compression socks get so smelly especially when paired with the hot box of a clog-style non-slip shoe. I have not had any problems with these!
