Today I am wearing my new sock. Damn it was tight getting it on. There is a special slippery sock you use to help put it on, then pull out through the toe hole. The constricting sock has an open toe. You start by turning most of it inside out then putting on the slippery sock, then stretching the constraining sock around that and pulling it up over your foot a little, then remove the slippery sock and carefully continue to move the constricting sock up your calf to its full length.
It was hard work getting it on but now I can hardly feel it. It's more comfortable than the looser cotton-based sock I had before. Supposedly it is helping the broken valves in my vein to function. My logical thought was that a constricting sock would make the circulation worse, but since it helps the valves it's supposed to improve circulation.
