Quick answer: the best socks for circulation are graduated compression socks: tightest at the ankle and gradually looser up the leg, which helps blood in the lower legs flow back toward the heart. For everyday support, 15-20 mmHg is the most common choice; 20-30 mmHg ("medical-grade") is for vein problems or swelling your doctor wants treated with firmer support. If you don't want compression, choose a non-binding sock so nothing tight squeezes your leg. And if poor circulation is from narrowed arteries (peripheral artery disease), compression can be unsafe, so check with your doctor first.
How compression socks help circulation
Blood in your leg veins has to travel uphill back to the heart. Calf muscles and one-way valves in the veins do most of the work, but long periods of sitting or standing, age, and weakened vein valves let blood and fluid pool in the lower legs. Graduated compression gently squeezes the veins, helping blood move upward and reducing that pooling. That's why people use them for heavy, tired legs, swelling, varicose vein discomfort, long flights, and, on medical advice, after surgery.
Best medical compression socks for circulation: what to look for
- Graduated compression with a clearly stated mmHg range
- The right strength: 8-15 mmHg (light), 15-20 mmHg (everyday support), 20-30 mmHg (medical-grade, usually with a doctor's advice). See compression levels explained.
- Knee-high or over-the-calf length
- Sized by calf and ankle measurement, using a compression size chart
- A comfortable top that stays flat
- Breathable, moisture-wicking fabric
Compression socks for circulation: men and women
The features are the same; the difference is sizing and looks. Our men's and women's over-the-calf compression socks come in 8-15, 15-20 and 20-30 mmHg, and you can choose a different strength for each pair. They're graduated, made from a breathable nylon and spandex blend, knit in Alabama and shipped free. Shop all diabetic compression socks.
Signs of poor circulation in the legs and feet
- Swelling in the feet and ankles, worse at the end of the day
- Heavy, achy or tired legs
- Cold feet or toes
- Numbness or tingling
- Skin color changes or sores that heal slowly
- Leg pain when walking that eases with rest (a sign of artery problems)
These can have many causes, so talk to your doctor. More in poor circulation in feet and signs of poor circulation for diabetics.
Vein problems vs. artery problems: why it matters
Compression helps with vein problems, where blood has trouble getting back up the leg (for example chronic venous insufficiency or varicose veins). It can be harmful with serious artery problems, where not enough blood reaches the feet in the first place (peripheral artery disease). Leg pain when walking, very cold or pale feet, and sores that won't heal are reasons to see a doctor before trying compression.
Socks for poor circulation without compression
If compression isn't right for you, the next best thing is a sock that doesn't make things worse: a non-binding top that won't squeeze the leg, soft moisture-wicking fabric, and a smooth toe seam. These don't improve circulation, but they avoid tight elastic pressing into your leg all day. See our diabetic socks and what non-binding socks are.
Other ways to support circulation in your legs
- Walk regularly; your calf muscles are your best circulation pump.
- Get up and move every hour if you sit a lot.
- Raise your legs for a while in the evening.
- Don't smoke.
- Keep blood sugar, blood pressure and cholesterol in range if you have diabetes.
Frequently asked questions
What are the best socks for blood circulation?
Graduated compression socks, knee-high or over the calf, at a strength that suits you, usually 15-20 mmHg for everyday support.
What is the best compression level for circulation?
15-20 mmHg for most everyday uses; 20-30 mmHg when your doctor recommends firmer support.
Are compression socks good for poor circulation in the feet?
For vein-related problems, often yes. If the cause is artery disease, compression may not be safe, so ask your doctor.
Can diabetics wear compression socks for circulation?
Many can, after checking with their doctor. See diabetic stockings and the benefits of compression socks.
Should I wear circulation socks to bed?
Usually not. Compression is for daytime, when you're upright.
