Yes, compression levels are important and must be considered. After 30 years of severe accidental leg / ankle / foot surgery, these compression socks are a game changer for me. They provide me with good compression and leg support.
I recommend the Physix Gear Compression Socks, which doesn't feel the sultryness of the legs during exercise because its fabric is 80% nylon and 20% spandex, very breathable. Although it is not ranked first in the men's compression socks brand review, it is still worth it.
