Do compression socks help with restless legs?

• It comes on when you are resting or sitting still

• It gets worse in the evening and at night

• Moving your legs relieves it, at least temporarily

• It comes back when you stop moving

It is more common than most people realise. Around one in ten people are affected at some point, women roughly twice as often as men, and it becomes more common in middle age.

 

 

This is the part that matters most, and it is the part most sock retailers skip.

 

Restless legs is thought to be linked to iron levels and to dopamine, a chemical in the brain involved in controlling movement. Low iron in particular comes up again and again in the research, and it is a common enough cause that Harvard Health has pointed out doctors often fail to test for it, especially in men.

 

That matters because iron deficiency is treatable. A blood test measuring your ferritin levels is simple, and if it turns out your iron is low, addressing that may improve your symptoms far more than anything you put on your feet.

 

Restless legs can also be linked to:

 

• Pregnancy, particularly in the later stages
• Chronic kidney disease
• Peripheral neuropathy
• Certain medications
• Poor circulation in the legs, including venous insufficiency

 

That last one is where compression starts to become relevant.

So do compression socks help?

The honest answer is that the evidence is limited, but it is not nothing.

The most useful study is a randomised controlled trial published in 2024, which looked at 63 pregnant women with restless legs. One group wore compression stockings, the other wore a placebo stocking that looked the same but applied no meaningful compression. Both groups improved, which tells you something about how much of this is expectation. But the compression group improved more, with a bigger reduction in symptom severity.

There is also research showing a strong overlap between restless legs and venous problems. A 2021 study found that a large majority of people with venous disease also had restless legs symptoms. That does not prove one causes the other, but it does suggest that for some people, poor circulation in the legs is part of the picture. If that is true for you, compression is doing something useful about the underlying problem rather than just masking a symptom.

What we would not say is that compression socks treat restless legs, or that they work for everyone. The trial above was small and looked at one specific group. Anyone telling you compression socks are a cure is selling you something.

What is reasonable to say is this. If your restless legs are connected to circulation, compression may help. It is low risk, it is inexpensive compared with most things you could try, and if it does not work for you after a few weeks you have lost very little.

When to wear them, and this bit is important

Here is where a lot of advice online gets it wrong.

Because restless legs is worse at night, people assume you should wear compression socks in bed. In the 2024 trial, the women put their stockings on in the morning and took them off at bedtime. The NHS also advises against wearing compression stockings in bed unless a healthcare professional has specifically told you to.

The reasoning makes sense once you think about it. Compression works by helping blood move back up the leg against gravity while you are upright. Lying down, gravity is no longer working against you, so the compression is not doing the job it was designed for. Wearing tight garments overnight without medical advice is not a good idea.

So the practical approach is:

• Put them on first thing in the morning, before any swelling builds up
• Wear them through the day, particularly if you sit or stand for long periods
• Take them off at bedtime

The idea is to arrive at the evening with your legs in better shape, rather than trying to fix them once you are already in bed.

What compression level do I need?

Compression is measured in millimetres of mercury, written mmHg. The higher the number, the firmer the squeeze.

Light compression, roughly 8 to 15 mmHg. Gentle support for tired legs and mild swelling. A sensible place to start if you have never worn compression before.

Mild to moderate, roughly 15 to 20 mmHg. The most common everyday level. Suits most people looking for support through a long day of sitting or standing.

Firm, 20 to 30 mmHg and above. This is medical territory. If you are considering this level, particularly for a diagnosed condition, talk to your GP or pharmacist first.

For restless legs, most people are best starting at the lighter end and seeing how they get on. Graduated compression, where the pressure is firmest at the ankle and eases as it goes up the leg, is the type you want. That gradient is what encourages blood back towards the heart.

Fit matters as much as the number. A compression sock that is too tight at the top will dig in and restrict rather than help, and one that is too loose does nothing at all. Measure your calf and check the size guide rather than guessing from your shoe size.

What else is worth trying

Compression is one option among several, and it is worth being straightforward that the NHS suggests a number of things before anyone mentions socks:

• Get your iron levels checked. This is the big one. Ask your GP about a ferritin test.
• Look at your evening routine. Caffeine, alcohol and nicotine in the evening can make symptoms worse.
• Move before bed. Walking, stretching or massaging your legs can settle symptoms when they come on.
• Try warmth. A warm bath or a heat pad on the legs before bed helps some people.
• Improve your sleep environment. Dark, quiet, cool. Restless legs and poor sleep feed each other.
• Check your medications. Some can worsen symptoms. Your GP can review them.

If your symptoms are severe, there are prescribed treatments available. That conversation belongs with your doctor, not a sock shop.

Choosing your socks

If you want to give compression a go, a few practical points.

Look for graduated compression rather than a sock that is simply tight all over. Check the mmHg rating is stated, because if a brand will not tell you the compression level, it probably is not offering meaningful compression.

Think about material. Bamboo and cotton-rich options are more breathable if you are wearing them all day, and softer against the skin if your legs are already irritable. If you have diabetes or any loss of sensation in your feet, be careful, and speak to a healthcare professional before wearing anything compressive.

Our range of compression socks covers everyday support levels through to sports compression, in cotton, bamboo and technical fabrics. If you are on your feet all day, or sat still for most of it, our flight socks are built for the same problem.

The short version

Restless legs is a real neurological condition, not just fidgeting. It is often linked to low iron, which is worth getting tested, and sometimes to poor circulation in the legs.

Compression socks may help, particularly where circulation is part of the problem. The evidence is encouraging but limited. Wear them through the day and take them off at night, start at a lighter compression level, and get the fit right.

And if it is keeping you awake, go and see your GP. A ferritin test costs you nothing and could tell you more than any pair of socks.
