Pregnancy is a beautiful and challenging time. Most experience problems linked to circulation and fluid retention, with foot and ankle swelling being a chief nuisance. In fact, 8 in 10 women experience edema when pregnant!
Regardless of your age or fitness levels, pregnancy puts strain on the circulatory system because of the added volume of blood and fluid, pressure on the blood vessels, and hormonal as well as physical changes. Luckily, using high-quality graduated compression socks and wearing them correctly during pregnancy can help reduce uncomfortable symptoms and health risks. In fact, research has shown that wearing compression legwear during pregnancy improves quality of life.
In this article, we’ll cover how long to wear compression socks during your pregnancy, when to wear them, sleep and other use cases, and some key comfort tips.
If you’re still deciding whether compression socks are for you, start with our guide on whether they are good for pregnancy for a fuller look at potential benefits.
How Long To Wear Compression Socks During Pregnancy
There is no single number of hours to match every pregnancy. Many people can wear graduated compression socks for 4 to 8 hours every day, but personal preference, health conditions, and familiarity with the feeling of therapeutic pressure will all play a role. Always consult your doctor if you have a history of circulation problems.
Medical research supports wearing compression socks for long periods during the day for best results. A randomized controlled trial with 60 pregnant women had an intervention group wear 20-30 mmHg compression socks for around eight hours per day. The result was that pregnant women wearing compression socks had MUCH LESS swelling in the ankle (up to 85% less) and calf (up to 92% less) than the pregnant women that did not wear them. This suggests that consistent daily wear of compression socks can help limit lower-leg edema during pregnancy.
But eight hours is not a magic number or a must-reach goal. Think of compression socks as a daytime support tool - they will work with your body, depending on your needs. If you’re new to compression, start with a trial of 2-3 hours first, then gradually increase this when you feel up to it.
Compression socks will be particularly helpful when you spend a long time sitting or standing (for example, at work or when traveling long-distance), when you notice a lot of swelling building up during the day, or if you’re struggling with heat edema.
When To Put Them On
The best time to put on compression socks for pregnancy is before the swelling builds up: first thing in the morning. This is because swelling tends to increase during the day, especially after you spend long stretches of time sitting or standing and fluid accumulates around the ankles or in your lower limbs.
If you’re heading for a long-haul flight where you won’t move around much, or if your work requires you to sit at a desk for hours on end, pull on your knee-high graduated compression socks while your legs are still fresh. Then, the therapeutic pressure will gently massage the lower limbs and support upward circulation that reduces the risk of fluid build-up. It’s easier than trying to put on close-fitting socks later, when your legs are already swollen and feeling heavy.
If your legs are already swollen, rest them first, elevated above the heart level. For example, lie on a couch and rest your feet on a couple of cushions. This will help blood flow back towards the heart, reduce the swelling, and take pressure off the legs.
Can You Sleep In Compression Socks When Pregnant?
Most people find compression socks for pregnancy to give the most benefits during waking hours. This is because, generally, the pressure from gravity, standing or sitting, is what can cause challenges in blood flow and fluid build-up more likely. When you lie down at night, you’ll usually not need your compression socks unless your doctor advises you to wear them.
However, this can vary depending on why you’re wearing compression socks, your overall health condition, your pregnancy, and the compression level, too. For example, if you struggle to sleep because of restless leg syndrome, your midwife or doctor may suggest overnight compression. And remember: you can go down in pressure, so that you may wear 15-20 mmHg compression socks at night, which will feel less restrictive than a pair of 20-30 mmHg would.

Which Compression Level Makes Sense
Compression socks are not all the same: the level of pressure applied, measured in millimetres of mercury (mmHg), signals how supportive they will feel. The right level depends on your medical history, but also on preference. Be sure to consult your medical provider.
15-20 mmHg is a common starting point for those new to compression or for everyday wear, supportive but not restrictive. UCI Health obstetrician-gynecologist Dr. Donna Baick describes 15-20 mmHg as milder support that may be comfortable for mild swelling, while 20-30 mmHg provides greater support for pregnant women. In fact, Dr. Baick said, “Compression socks are specialized stockings that help improve blood flow and support the lower legs and feet. They can help pregnant women alleviate painful swelling of the legs and feet, which can also lead to varicose veins.”
Vim & Vigr compression socks come in both moderate 15-20 mmHg and firmer 20-30 mmHg levels. These are available without prescription, but we do recommend checking with your doctor before increasing the compression level. If your circumstances warrant it, your doctor may even prescribe 30-40 mmHg compression. Finally, pregnancy compression tights can be a good option for support that extends up the leg.
How To Make All-Day Wear Comfortable
Concerned that compression may feel uncomfortable or restrictive? Wearing compression socks or tights when pregnant can feel great, as long as you focus on the right fit, fabric, and overall feel. The right pair will feel snug and supportive, but not painful or numbing.
To begin, size is essential. Increased blood volume during pregnancy can lead to changes in calf and ankle measurements, so start by retaking these before placing an order. If the top band of your trusted socks starts to dig in or they feel too restrictive, it may be time to go up in size. Consult our sizing chart on every product page to map against the right information.
Next, choose the right fabric for your activity and environmental conditions. Breathable cotton is a comfortable everyday choice, while moisture-wicking materials are better if you are warm, spend long days on your feet, or live in a humid climate. Merino wool is an excellent choice for temperature regulation and for sensitive skin, thanks to its hypoallergenic properties.
Calf muscles widened because of pregnancy? The Vim & Vigr collection includes special wide-calf sizes to accommodate this. Finally, open-toe compression is a good alternative for those hot days when you simply want to wear sandals.
The key thing to remember is that compression should not hurt. Remove your socks and review the fit immediately if you’re starting to get pins and needles, numbness, skin discoloration, or pain.
How To Put Them On More Easily
The benefits of compression socks in pregnancy and more generally are closely linked to the snug fit, applying therapeutic pressure to the legs to boost circulation. This can make them harder to pull on than ordinary socks, especially later in pregnancy when you can’t reach your feet so easily.
The easiest approach is:
-
Put your socks on first thing in the morning, when the legs are the least swollen
-
Gather the sock toward the heel, put your toes in through and make sure they align with the toe seams, then align your heel in the heel cup
-
Then, gently roll up the sock toward just below the knee
-
Check for folding or bunching; the socks should be smooth against the skin and there shouldn’t be any pressure points
If you’re finding it difficult to bend down or reach your feet, you can use a compression sock donner, or ask for help. Our step-by-step guide explains how to put on compression socks without overstretching the fabric or fighting with the fit.
When To Ask Your Doctor
Swelling during pregnancy is relatively common and compression socks can help reduce the symptoms and improve everyday comfort. However, they are not a substitute for medical care: if something feels unusual, you should always check with your midwife or doctor.
Contact your healthcare provider if:
-
Swelling is sudden or painful
-
There is markedly more swelling on one side of the body than on the other
-
Swelling is accompanied by redness or warmth
-
You experience headaches that won’t go away or vision changes
-
You experience abdominal pain, nausea (later in the pregnancy), or difficulty breathing
If you already have an existing circulation problem, a history of blood clots, or a condition that can affect blood flow to the legs, ask your doctor about using compression garments.
Pregnancy And Postpartum Wear
Your need for circulation support and compression wear doesn’t necessarily end with giving birth. Many women find that fluid shifts, reduced mobility, and postpartum swelling leave legs continuing to feel heavy. This is where postpartum compression socks can help.
How long you wear the socks after giving birth depends on the type of delivery, your mobility, how much swelling you experience, and the risk of blood clots. Don’t just extend your pregnancy routine. Follow your doctor’s advice and use our dedicated guide to how long to wear compression socks postpartum for more guidance.
FAQs About Pregnancy Compression Socks
How many hours a day should I wear compression socks while pregnant?
Many people wear their socks for most of their waking day, but there is no universal hourly target. Put them on before swelling develops and wear them when you need support, provided they remain comfortable and your healthcare provider has not advised otherwise.
Is it okay to wear compression socks every day during pregnancy?
For many pregnant people, yes. Daily daytime wear may be useful if you regularly experience swelling or spend long periods sitting or standing. Correct fit and compression level are essential, so check with your healthcare provider if you have circulatory problems or significant symptoms.
Should I wear compression socks on flights while pregnant?
Compression socks are commonly used during flights because long periods of sitting can encourage blood and fluid to pool in the lower legs. Put them on before you travel rather than waiting for swelling to appear, and keep moving when possible by walking periodically and flexing your ankles and calves. If you have additional risk factors for blood clots, ask your healthcare provider for individualized travel advice.
During your pregnancy, the easiest routine is the most practical in most cases: put your compression socks on early before the swelling starts, wear them while you’re out and about, sitting or standing for long periods of time, and remove them before bed unless your doctor recommends otherwise. Pair compression sock wear with gentle exercise and resting your legs with your feet elevated to improve circulation. And, remember: compression shouldn’t hurt and it doesn’t have to be dull.
