Dr. Scholl's graduated compression support socks are designed to provide your legs with the comfort and relief you need every day. The socks are constructed with the greatest support at the ankle that graduates up the leg to improve circulation, which energizes, renews, and restores leg comfort. These open toe, medical- grade socks feature a firm 20-30 MMHG compression level. Graduated compression socks help with tired, achy legs, varicose veins, edema, swelling, traveling, post-surgical procedures, and deep vein thrombosis.
