8-15 mmHg: This is the lightest form of compression, which is great for energizing your legs. These types of socks provide relief from tired and achy legs. They also help control minor swelling by gently enhancing circulation in the legs.
15-20 mmHg: The mild compression of 15-20 mmHg socks provides relief from minor to moderate swelling, aching, and varicose veins, especially during pregnancy. They are great for preventing deep vein thrombosis (or economy class syndrome) while traveling, but they’re also good for anyone who stands or sits for long periods of time.
20-30 mmHg: The most frequently prescribed level, 20-30 mmHg compression socks offer moderate compression and can be used to treat a variety of mild to moderate conditions. This level can provide relief from varicose veins, edema, deep vein thrombosis, and post-sclerotherapy. This level is also referred to as Class I or firm compression.
