Compression Socks for Varicose Veins: What They Can and Can’t Do

Compression socks for varicose veins can ease aching, heaviness and ankle swelling while you wear them, and the usual choice is a 20–30 mmHg knee-high. They are not a cure, and the trials behind them are weaker than the marketing suggests. The right pair is the strength your clinician agrees, sized to your legs, in a style you will actually put on every morning.

Signs that need a clinician, not new socks

  • Call 911 for a varicose vein that is bleeding heavily; for sudden breathlessness, chest pain, coughing up blood, a racing heartbeat or fainting; or for a leg or foot that suddenly turns cold, pale or mottled, numb, weak or severely painful.
  • Be seen today if one leg has newly swollen or become painful, warm, red or discolored; if a hard, red, tender vein comes with swelling of the leg; or if a varicose vein has bled, even if it has stopped.
  • Be seen the same day or the next day for a hard, red, tender vein on its own, or a sore near the ankle that is not healing. When to worry about varicose veins →

What compression can and cannot do for varicose veins

Compression stockings squeeze the leg to keep blood from pooling in the legs. The Society for Vascular Surgery (SVS) says knee-highs, usually at 20–30 mmHg, often ease aching and swelling, and Mayo Clinic calls wearing them all day often the first approach to try. It is a symptom benefit, and StatPearls notes that compression helps only people who keep wearing it.

The evidence is thinner than the packaging implies. A 2021 Cochrane review of 13 trials, covering 1,021 people and pressures from 10 to 50 mmHg, found too little good evidence to say whether stockings work as the first and only treatment for varicose veins, or which type, length or pressure is best. People reported feeling better while wearing them, and swelling was lower than with placebo stockings in one of the two studies that measured it, but the evidence was rated low or very low in certainty.

NICE, the UK guideline body, advises against offering stockings to treat varicose veins unless a procedure is unsuitable. Here is how the common uses stand, using the evidence labels in our methodology:

Use Evidence label What it means here
Easing aching, heaviness and swelling Established clinical use Supported by the SVS and MedlinePlus, and by NICE when a procedure is unsuitable, though the trials behind it are low in certainty
Swelling from varicose veins in pregnancy Useful in selected circumstances NICE says to consider stockings for symptom relief; Cochrane found pregnant women increasingly turned down compression tights as pregnancy went on
Short-term wear after a vein procedure Useful in selected circumstances The NHS says you may need them for about a week; StatPearls notes there is no consensus on whether they are needed or for how long
Instead of a procedure, when one is suitable Limited or conflicting evidence NICE advises against it, and Cochrane could not show stockings work as the sole first treatment
Stopping veins worsening, or new ones forming Limited or conflicting evidence The SVS says wearing them after treatment helps prevent new varicose veins; the sources we checked cite no trial that settles it
Shrinking or removing varicose veins Unsupported claim None of our sources says stockings remove veins; StatPearls notes there is no cure

Who should get advice before buying

  • Anyone who needs an artery check first. The NHS says compression stockings are not suitable if you have problems with arterial blood flow, and StatPearls lists severe arterial disease and uncompensated heart failure as reasons not to use compression. Have your arterial circulation checked first, usually with an ankle-brachial index (ABI), if you have diabetes, leg pain on walking or other signs of PAD, numbness in your feet, a wound, kidney disease or heart failure. Compression safety: who needs an assessment first →
  • Anyone with skin changes, a sore or a hard, painful vein. NICE lists each of these as a reason for referral to a vein service, so get them assessed before choosing a garment.
  • Anyone planning a vein procedure. The SVS notes that insurers may require at least three months of stockings before covering other treatment, and Mayo Clinic says insurance might cover prescription stockings when varicose veins cause symptoms. The 2023 guideline from the SVS, American Venous Forum and American Vein and Lymphatic Society suggests against a three-month trial for people with symptomatic varicose veins who are candidates for a procedure and want to proceed, but your plan’s rules still apply. Ask your plan what it needs documented, note the dates, strength and how your symptoms changed, and ask the clinic what you will wear afterward. Vein procedures and the questions to ask →
  • Pregnancy. NICE suggests considering stockings for swelling from varicose veins in pregnancy. Maternity styles are covered in compression socks in pregnancy.

What matters when choosing

Feature What to look for Why it matters
Strength 20–30 mmHg, labeled graduated, unless your clinician says otherwise The SVS and StatPearls give 20–30 mmHg as the usual strength; StatPearls says 30–40 mmHg may be used in more severe cases, which is your clinician’s call
Length Knee-high for most people The SVS refers to knee-highs, and Cochrane could not show that longer is better; choose thigh-high or tights when your clinician asks for them
Size Ankle and calf (and thigh, for longer styles) measured in the morning, matched to that maker’s chart Charts differ: the products below use sizes I–V, I–VII, S–XL, S–2XL or shoe-size bands. SIGVARIS and Therafirm both say to measure as soon after waking as possible, before swelling builds
Look and feel Sheer, opaque, cotton or merino blends In the Cochrane trials, discomfort, difficulty putting them on and appearance were among the reasons people gave for not wearing them
Toe Open or closed toe, as your clinician or fitter recommends medi and Juzo offer both; the other options below are closed-toe or do not say
Top band A silicone border on thigh-highs; a waistband that stays flat on tights A band that rolls or slips concentrates pressure in one line
Fabric for warm weather Moisture-wicking or breathable knits StatPearls notes that heat and hot weather reduce how often people wear them
Care Machine-dryable, or hand wash only Two pairs in rotation make daily wear realistic

How to measure and put them on is in compression fit and pressure labels. If your hands or hips make stockings hard to pull on, see zipper socks and donning aids.

Compression socks for varicose veins: options by need

These are examples of each type, not a ranking. Each maker states the pressure in mmHg, and the details are what its own product page listed when we checked in October 2026, not our measurements. Plain medical knee-highs from JOBST and Truform are in our main compression socks guide, so they are not repeated here.

An everyday medical knee-high that looks less medical

mediven comfort calf high, 20–30 mmHg, closed toe. A semi-transparent medical stocking that medi lists for varicose veins and tired, achy, heavy legs, with moisture-releasing and odor-control finishes and a reinforced foot. Seven sizes in standard and petite lengths and six colors (not every color comes in every style); an open-toe version and 15–20 and 30–40 mmHg strengths are also listed. See it on Amazon

May suit: a first pair worn under work clothes. Limits: it looks like hosiery rather than a sock, sizes follow medi’s own chart, and the product page gives no washing guidance, so follow the label.

If comfort is what stops you wearing them

Juzo Soft knee high, 20–30 mmHg. An opaque, unisex stocking that Juzo calls extremely soft and elastic, listing varicose and spider veins, varicose veins in pregnancy, and use before and after vein procedures among its indications. Open or closed toe, five sizes in regular, short and petite lengths, machine washable and dryable; 15–20 and 30–40 mmHg, thigh-high, pantyhose and maternity versions are also made. See it on Amazon

May suit: people who gave up on firmer stockings because of how they felt. Limits: “soft” is the maker’s description, not something we measured.

A cotton-blend sock for men

SIGVARIS Men’s Essential Cotton Calf, 20–30 mmHg. A medical knee-high with 25% Supima cotton, 50% nylon and 25% spandex, non-latex, in small to extra-large with short and long lengths, in black, light beige, navy or white. SIGVARIS says its products can be machine washed and dried and guarantees their compression for six months; a 30–40 mmHg version is also made. See it on Amazon

May suit: men who want something closer to a dress or casual sock. Limits: cotton is a quarter of the fiber, and the page lists swelling-related uses rather than varicose veins by name. A women’s Essential Cotton Calf is listed too, which we did not check in detail.

Something that looks like an ordinary sock

Sockwell Men’s Elevation, firm graduated compression, 20–30 mmHg. A merino wool and bamboo rayon blend (31% each, with stretch nylon and spandex) with an ultra-light cushion sole, sized by shoe size: M/L for men’s 7 to 10, L/XL for 10.5 to 13 and XXL for 13.5 to 16. A women’s Elevation in the same blend is listed in S/M and M/L. See it on Amazon

May suit: people who will only wear compression that looks like a regular sock. Limits: sizing is by shoe size, with no calf measurements in the page text, so calves that are large or slim for the foot may not fit; Sockwell’s page talks about support and circulation in general terms and makes no varicose vein claims. For larger calves, see wide-calf compression socks.

Thigh-high, when your clinician asks for it

Knee-highs are the usual choice, and Cochrane could not show that longer stockings work better. Wear a thigh-high when your clinician asks for one, for example if swelling extends above the knee, or after a procedure, when the length prescribed varies from clinic to clinic. Fit problems with thigh-highs are covered in our thigh-high guide.

Juzo Dynamic thigh high, 20–30 mmHg, with beaded silicone border. A firm, unisex stocking that Juzo calls extremely durable and says stays in place during activity, listing varicose veins and use before and after vein procedures among its indications. Open or closed toe, five sizes in regular, short and petite lengths, machine wash and dry; knee-high, pantyhose, 30–40 and 40–50 mmHg versions are also made. See it on Amazon

Therafirm Women’s Moderate Support Lace-Top Thigh High, 20–30 mmHg. A closed-toe thigh-high with a reinforced toe and a lace top band with a silicone border, which Therafirm says needs no garter belt. Small to 2X-large, black or sand, made in the USA; hand wash and lay flat to dry. See it on Amazon

May suit: swelling that extends above the knee, or thigh-length compression your clinician has asked for. Limits: a firm thigh-high is harder to pull on than a knee-high, a band that slips or rolls concentrates pressure, and Therafirm’s page lists swelling and tired legs rather than varicose veins among its uses.

Tights

Therafirm Moderate Support Pantyhose, 20–30 mmHg. Opaque, closed-toe pantyhose with a reinforced toe and a non-restrictive waistband that Therafirm says prevents rolling, with a moisture-wicking finish. Small to 2X-large, black or sand, made in the USA; hand wash. A 15–20 mmHg version is also listed. See it on Amazon

May suit: women or men whose clinician recommends full-leg compression, or who prefer tights to stockings. Limits: no petite or tall lengths are listed, and the page names swelling and tired, aching legs rather than varicose veins among its uses.

Downsides and limits

  • They work only while worn. The NHS advises wearing them during the day and taking them off at bedtime, and the relief does not outlast the wearing.
  • Side effects are usually minor. The Cochrane trials reported sweating, itching, irritation, dry skin and a feeling of tightness, with no severe or long-lasting effects.
  • Pain is not part of the deal. Numb, tingling or discolored toes, or skin that blisters or breaks, means take them off and get advice; the compression safety guide linked above lists the warning signs.
  • Sizes do not transfer between brands, and MedlinePlus says stockings should feel tight around your legs, with the most pressure at the ankle, so a pair that feels loose may not be giving enough pressure.
  • Coverage varies. Check your plan before buying, and check the seller’s return policy.

Alternatives, including not buying

  • Treating the veins. If a procedure is suitable, NICE prefers it to stockings, and the NHS describes endothermal ablation as usually the first choice. Vein procedures and the questions to ask →
  • Moving more, and raising your legs. Mayo Clinic suggests exercise, raising your legs and changing position often. In advanced artery disease, foot pain can worsen with the legs raised; with heart failure, ask before long spells with your legs up. Leg elevation →
  • Nothing at all. The NHS says varicose veins do not always need treatment. Visible veins that cause no symptoms are not a reason to buy anything.

Questions to ask your clinician

  • Have my arteries been checked, and is 20–30 mmHg right for me?
  • Knee-high, thigh-high or tights, and do I need professional measuring?
  • Does my insurer need a documented trial of stockings before a procedure?
  • If I have a procedure, what should I wear afterward, and for how long?

Common questions

Do compression socks help varicose veins?

They can ease aching, heaviness and swelling while you wear them: the SVS says they often do, and Mayo Clinic calls them often the first approach to try. They do not remove the veins, and a Cochrane review found the trial evidence too weak to show they work as the only treatment.

What are the best compression socks for varicose veins?

There is no single best pair. The best compression socks for varicose veins are at the strength your clinician agrees, usually 20–30 mmHg, sized from morning measurements on that maker’s chart, in a style you will wear every day. Get your arteries checked first if you are in a higher-risk group.

Is 20–30 mmHg good for varicose veins?

It is the usual strength: the SVS and StatPearls both give 20–30 mmHg, and StatPearls says 30–40 mmHg may be used in more severe cases. Lighter or stronger pressures are a decision to make with your clinician, after an arterial check if you are in a higher-risk group.

Should I wear knee-high or thigh-high compression for varicose veins?

Knee-high for most people. Cochrane could not show that longer stockings work better, and knee-highs are easier to put on. Thigh-highs or tights make sense when your clinician asks for them, for example if swelling extends above the knee or after a procedure.

How long do you wear compression stockings after vein treatment?

As long as the team that treated you says. The NHS says you may need them for about a week after ablation, foam sclerotherapy or surgery, and NICE advises no more than 7 days when they are used after treatment. StatPearls notes there is no consensus, so US clinics’ instructions vary.

Do I need to wear compression stockings before insurance covers vein treatment?

Sometimes. The SVS notes that insurers may require at least three months of stockings before covering other treatment, although the 2023 SVS, American Venous Forum and American Vein and Lymphatic Society guideline suggests against a three-month trial for people with symptomatic varicose veins who are candidates for a procedure and want to proceed. Your plan’s rules still apply, so ask what it requires, and keep a record of when you started, the strength and your symptoms.
