I bought these CEP compression socks a few months ago as a recovery tool for running. They are probably the most expensive sock you will ever buy at $60 retail. There are a ton of options and brands out there but what is interesting about this German company is that they initally made these socks for medical reasons; for patients with varicose veins. i got this one because it encompasses the whole foot and calf area. Check out their link to learn more about what they claim the sock will do.
But basically, their “medi compression” applies pressures in such a way that increases blood flow to your blood vessels and ensures proper flow back to your heart - hence more oxygen faster recovery.
I typically wear them for a few hours following a long or intense run (though i admit i also throw them on after a 3 miler as well). I’ve heard some people sleep in them, too. I will say that i do feel a bit fresher and better the next day when going out for another run. However, it really only helps the area that the sock covers - hence the calf and foot area. But my quads are still tight and sore. So, i checked out their site and they have another product called Clone Compression tights which are customized. The full tight costs $289 and the thigh high costs $239. Ouch! but the tight encompasses the entire leg area which is what you would really need to feel “recovered.” They are marketing this particular product toward elite athletes but i think it definitely will move into the mass market at some point. Here is the link to the tights:
