Be Careful! Manufacturer sizes their product smaller than normal.
You must unzip and invert these socks down to the heel and pull them by the heel until they are beyond your ankle. Then you can pull the rest of the sock over your calf to the knee. At that point, you MUST hold the sock together above the zipper by about 2 inches and zip that 2 inches. Repeat that process until you reach to top. If you try to pretend that these are "slip on", you will probably destroy the sipper or tear the zipper from the sock. Take your time. Be careful. They actually do extend all the way up to the knee. Many other compression socks only cover the bottom part of the calf. Treat them right, and they will get the job done.
