This is my third time purchasing these socks. I love them. When I purchase I buy 8 pairs. Wear them daily for about two years and then replace. They are extremely comfortable when new, can start pinching the toes after a year of washing. But they are durable and give good compression. I have had both legs stripped of vericose veins, and work as a truck driver, so lots of sitting. The veins have not come back and my circulation has stayed improved.
