Dr. Scholl's graduated compression support socks with coolmax are designed to provide your legs with the comfort and relief you need every day. The socks feature a firm 20-30 MMHG compression level and are constructed with the greatest support at the ankle that graduates up the leg to improve circulation. Compression socks help with tired, achy legs, varicose veins, edema, swelling, traveling, post-surgical procedures, and DVT (deep vein thrombosis).
