Compression socks for runners are a super strong elastic sock, typically worn up to the knee. They compress veins on the surface of your leg, as well as arteries and muscles, so that blood is circulated through your legs through smaller circulatory channels.
Compression stockings work by decreasing venous pressure and increasing venous return. They should not cut off the circulation. However, if they do not fit properly or are not worn properly, they will be uncomfortable and not do the job.
