- 20 to 30 mmHg knee-high stockings, closed toe. Best for: Symptomatic varicose veins below the knee. See options on Amazon
- 20 to 30 mmHg thigh-high stockings with a grip band. Best for: Veins that extend above the knee. See options on Amazon
- 15 to 20 mmHg everyday socks. Best for: Mild heaviness, small veins, or prevention on long standing days. See options on Amazon
- Open-toe medical stockings. Best for: People who need firm compression but have toe pressure issues. See options on Amazon
What varicose veins are, briefly
Veins in the legs carry blood uphill to the heart. MedlinePlus explains that valves in the leg veins normally keep blood moving forward. When vein walls weaken and valves are damaged, blood pools in the legs, especially when you stand. That pooling is what stretches surface veins into the twisted, bulging shape most people recognize.
MedlinePlus describes the typical symptoms as aching, heaviness or cramping in the legs that is often worse while standing and better when the legs are raised. Some people also get swelling and skin changes around the ankles.
What compression socks can and cannot do
Mayo Clinic says compression stockings squeeze the legs, helping veins and leg muscles move blood. It calls daily wear often the first approach to try, and notes that prescription-strength versions exist.
Set expectations honestly:
- They may help: leg ache, heaviness, end-of-day swelling.
- They will not: shrink or remove visible veins. Procedures such as sclerotherapy or vein removal are a separate conversation with a vein specialist.
- After a procedure: Sigvaris lists 20 to 30 mmHg for use after sclerotherapy or phlebectomy. Follow your own specialist's instructions on level and timing.
Pressure: why 20 to 30 mmHg comes up so often
Sigvaris describes 20 to 30 mmHg as the level doctors prescribe most often, and lists varicose veins among its uses. It puts 15 to 20 mmHg at achy, heavy or slightly swollen legs, and says this lower level may help prevent varicose and spider veins during pregnancy. It reserves 30 to 40 mmHg for serious varicose veins, DVT and post-thrombotic syndrome.
| Your situation | Level to discuss | Buy how |
|---|---|---|
| Small veins, mild heaviness at day's end | 15 to 20 mmHg | Over the counter |
| Symptomatic varicose veins | 20 to 30 mmHg | Usually after a doctor visit |
| Large veins with skin changes or past clots | 30 to 40 mmHg | Prescription and fitting |
Mayo Clinic notes insurance might cover prescription stockings if your varicose veins cause symptoms, which is one more reason to get a visit on the record.
Picking the length
Length should match where your veins are. Knee-high socks cover the ankle and calf, which is where most people feel symptoms and where the pressure gradient does most of its work. If your varicose veins run above the knee or along the inner thigh, ask your clinician whether a thigh-high stocking makes more sense. Our guides to knee-high and thigh-high compression socks cover fit for each.
Self-care that adds to the socks
Mayo Clinic lists simple steps alongside compression:
- Get regular exercise; walking is a good way to improve leg blood flow.
- Raise your legs above heart level for short breaks each day, for example lying down with your legs on three or four pillows.
- Avoid tight clothes around the waist, legs or groin.
- Avoid sitting or standing still for long periods.
MedlinePlus adds weight loss if overweight and care for any open sores. If a sore near the ankle is slow to close, that is a reason to see a clinician, not to buy a firmer sock.
Before you buy: a safety check
Varicose veins and artery disease can exist in the same leg, especially in older adults and people with diabetes. medi lists circulation disorders in the leg arteries as a reason not to wear compression and calls advanced peripheral artery disease (PAD) a contraindication. It also urges caution if diabetes or neuropathy has reduced feeling in your feet. A quick ankle pulse or ankle brachial index check before firmer compression is a reasonable thing to ask for.
What to look for when you buy
20 to 30 mmHg knee-high stockings, closed toe
Best for: Symptomatic varicose veins below the knee
Sigvaris lists 20 to 30 mmHg for varicose veins and calls it the most prescribed level. Knee length covers the calf, where most symptoms sit.
Watch out: Check with a doctor first if you have diabetes, numb feet or signs of artery disease.
See options on Amazon20 to 30 mmHg thigh-high stockings with a grip band
Best for: Veins that extend above the knee
A thigh-high carries the gradient higher up the leg. A grip band helps keep it from sliding, which keeps pressure where it is meant to be.
Watch out: Harder to put on; some people find a knee-high they will actually wear more useful than a thigh-high they skip.
See options on Amazon15 to 20 mmHg everyday socks
Best for: Mild heaviness, small veins, or prevention on long standing days
Sigvaris lists 15 to 20 mmHg for achy, heavy legs and possible prevention of varicose and spider veins in pregnancy. No prescription needed.
Watch out: May feel too light once veins cause swelling or skin changes.
See options on AmazonOpen-toe medical stockings
Best for: People who need firm compression but have toe pressure issues
An open toe takes pressure off the toes while keeping the graduated pressure over the ankle and calf.
Watch out: The toe opening can roll if the foot size is wrong.

- Do compression socks get rid of varicose veins?
- No. Mayo Clinic describes them as a way to help veins and muscles move blood, which may ease symptoms. Removing veins takes a procedure.
- What mmHg is best for varicose veins?
- Sigvaris lists 20 to 30 mmHg for varicose veins and 30 to 40 mmHg for serious varicose veins. Your doctor should set the level.
- Should I wear knee-high or thigh-high socks for varicose veins?
- Match the length to where the veins are. Knee-highs suit veins below the knee; ask about thigh-highs if veins run up the thigh.
- Will insurance cover varicose compression socks?
- Mayo Clinic says insurance might cover prescription stockings if your varicose veins cause symptoms. Check your plan.
- When should I see a doctor about varicose veins?
- MedlinePlus says to contact a provider if they are painful, if self-care such as compression does not help, or if you have sudden leg pain or swelling, fever, redness or sores.
