I have tried compression socks from CEP, "pro compression", CW-X, Saucony and Some
Amazon Medicated ones.
For me the CEP socks are the most comfortable, but the Pro Compression and the weird medical Compression socks seem to have more compression. I don't know if it's just the medical and pro compression socks are too small.
From Pro-Compression info these are the amounts of pressure exhibited by compression gear and the purpose of that pressure level.
8-15 mmHg: This is the lightest amount of pressure that will be placed on your limbs. It’s ideal for those with tired or achy legs that need a subtle boost in circulation.
15-20 mmHg: This range treats mild conditions such as varicose veins and the aches and swelling caused by pregnancy or traveling for long periods. Compression socks in this range are ideal for anyone who sits or stands for a long period of time and can help prevent deep vein thrombosis from occurring.
20-30 mmHg: This is the compression-level sweet spot for many compression sock wearers. It means you’ll experience a moderate pressure on your limbs. Those with edema, deep vein thrombosis or varicose veins will appreciate socks that fall in this range. Compression socks with moderate-level compression are also ideal for many types of athletes including runners.
30-40 mmHg: This range treats more severe conditions of edema and often treats those suffering from active venous stasis ulcers. Socks at this level will most likely require a doctor’s prescription as they are considered a more intense form of treatment.
40-50 mmHg: This is the highest compression level that is mainly prescribed by doctors to treat chronic venous conditions.
CEP's Running compression socks are in the 20-30 mmHG.
If your looking for CEP socks leftlane sports usually has them marked down a lot, but the colors may be crazy.
