As the name suggests, the length of knee-high compression extends up the calf and stops just below the knee. This stocking length can treat a variety of medical conditions including deep vein thrombosis, edema, and swollen feet. Knee high compression socks use gradient compression along the length of the stocking to stimulate blood flow. Most knee high stockings have a band at the top that prevents the sock from rolling down. Knee high compression socks are great to wear when traveling by plane, as many people experience swelling in the legs and feet while flying.
