Quick Summary
With an overwhelming amount of positive reviews from What to Expect’s community of moms, the best compression socks for pregnancy are Comrad’s Knee High Compression Socksbecause they offer breathable comfort for all-day wear and come in various sizes and heights.
Compression socks weren’t on my radar during the early days of pregnancy. In fact, I hadn’t even considered them until my doctor suggested I try them to address chronic nerve pain. At first, I panicked — was something wrong? But as it turns out, compression socks are a popular pregnancy accessory.
“Compression socks are used during pregnancy to improve circulation, prevent varicose veins and reduce swelling (edema in the legs),” says Dr. Jill Hechtman, board-certified OB/GYN at Pediatrix Medical Group. According to Dr. Hechtman, your growing uterus can put pressure on the veins in your legs, decreasing blood flow, which causes swelling (it affects about three-quarters of pregnant women!). “In pregnancy, the body is at increased risk of blood clots,” she adds, but compression socks have been proven to help.
And unlike most of your maternity wardrobe, compression socks are a fantastic tool to help with postpartum swelling or promote better blood flow while traveling or working at a desk job. Once you find a pair or two you like, you’ll likely get plenty of use out of them later.
But finding the best possible pair of compression socks for you is easier said than done. I was overwhelmed by the options. Did I need mild or moderate compression? And what does mmHg even mean, anyway? If shopping for the best compression socks for pregnancy has you just as confused (or crying all the frustrated tears — hello, hormones!), I’ve got your back with answers to all of your questions along with 10 mom-approved and doctor-vetted pairs.
How I Chose the Best Compression Socks for Pregnancy
When you're desperate for relief, you may be quick to grab the first pair of compression socks you see. But compression socks aren’t one-size-fits-all, so a little research is required before you add them to your cart.
To help with that process, I spoke to Dr. Hechtman and Iffath Hoskins, M.D., an OB-GYN at NYU Langone Health in New York City to learn how compression socks work and what to look for to maximize their effect. I also reviewed recommendations from the American Pregnancy Association. Based on this guidance, the best compression socks for pregnancy will:
Offer graduated compression, meaning the pressure is greatest towards the feet and gradually lessens up to the knee, allowing for better blood flow.
Or provide adequate compression, but are comfortable.
Have at least knee-high coverage to promote the best level of circulatory support during pregnancy. “There are plenty of choices on the market, but what is most important is comfort. I recommend knee-high socks that have between 20-30 mmHg,” Dr. Hechtman says. “You don't want them too loose or too tight.”
I leaned heavily on my own experience as a mom of two who regularly wears compression socks to support healthy blood flow and alleviate chronic nerve pain in my lower legs and feet, considering around 30 brands of compression socks suggested by What to Expect’s community members. I gathered any recommendations that met Dr. Hechtman and Dr. Hoskins’s standards and narrowed down my list to the top 10 based on which factors were most important to moms, including those:
Made of comfortable fabric.
Easy to put on and take off.
Available in a wide range of sizes.

For pregnancy relief, moms in the WTE community mention Comrad compression socks most often, and hundreds of other parents agree. In fact, these are the compression socks I wear almost daily, and they’ve reigned supreme in terms of stretch and breathability. A couple of years ago, I invested in two three-packs to get more bang for my buck, and they’re all still going strong today. While working from home, these have helped stabilize my blood flow and decrease nerve pain in my feet, which has developed over decades of dancing.
Another reason to like these popular compression socks: They come in a variety in colors and prints, including a fun speckled confetti, stripes and ombre colorways.
Made of a stretchy recycled cotton and nylon blend, they’re easy to get on, plus they have a cushioned heel and toe for added comfort. The graduated compression is also great if you don’t need or want anything too intense, making them ideal for all-day wear.
While we love this basic knee-high style, Comrad’s website also shows a variety of heights (like ankle) and compression levels(from light to firm). There’s truly something for everyone. However, it’s worth noting that some reviewers said these were too tight on wide calves, so if you need larger sizing, these might not be ideal.
"I have a few pair of knee high Comrad brand compression socks - they are great and offer multiple levels of compression and have multiple calf size options. I’m on my feet a lot for my job and they have made me feel great at the end of the day!"
“I love the ones from Comrad, both for flying and day where I know I’ll be on my feet a lot..they have some minimalistic but cute options and different compression levels”
“I just got these COMRAD compression socks for when I'm walking or standing, running errands, etc, and they seem to be helping with that feeling of heavy, swollen feet. A friend recommended them to me”
“Highly recommend COMRAD compression socks, my OB recommended them to me I have been wearing them the whole last trimester of my pregnancy and they are amazing.”
SB Soxhas thousands of positive reviews happy testimonials within the WTE community. With a firm compression of 20 to 30 mmHg, they’re ideal for long flights, especially for people with more uncomfortable swelling brought on by the second trimester. Additionally, there are a lot of features that make them great to wear in the sky — or on the ground.
To start, the reinforced heel and toe area make them extra comfortable and prevent blisters from popping up after walking through the airport. They also provide graduated compression, getting less tight further up in the leg, alleviating any discomfort and swelling that comes from sitting still over long periods of time on a plane.
Reviewers love how much support they give, and how well they stay up on their legs, and the fact that the thick fabric construction isn’t too stifling. Some did note, however, that they felt a little tight for anyone with wide feet or calves.
"I too have terrible varicose veins. I love SB Sox. They sell them on Amazon and they are fairly easy to put on and come up pretty high. I use a belly band a lot too to help take pressure off my legs a little."
“My go to sock for the last several years and I've even gotten my husband wearing them when he travels, is SB Sox on Amazon. Be aware these are firm compression (20-30mmHg). If you don't want that much compression look for one's that say 15-20mmHg. But I feel like these have a bit of compression on my foot and up my leg. I have wide calves and can get them up and they stay all day.”
“I wore them during my pregnancy (and before) because I had a DVT previously. I liked SB Sox which I got from Amazon. They were good value, wash well and look more like ordinary knee socks. The compression was medical grade but made me feel like less of a granny! They have a measuring guide.”
Compression socks can help improve performance and boost recovery during exercise. You just want to make sure you wear a pair that can stand up to sweat while relieving pressure. The Zensah Tech+ socks do just that, due in large part to the stretchy, lightweight, moisture-wicking fabric. (In fact, several reviewers say their feet barely sweat in these socks.) The fabric is also super durable, standing up to multiple post-workout washes.
Offering moderate compression, these socks are designed specifically for your left and right foot to ensure a perfect fit, which, along with the seamless toe, helps prevent chafing and blistering. Plus, they come in an array of colors and patterns, so you won't mind wearing them to the gym or workout class.
The only downside to these otherwise perfect socks is the price, but moms say they’re totally worth the $50 splurge forexercise during pregnancy.
Bombas is known for its quality, comfortable socks, so it's no surprise that these compression socks come highly recommended by moms in the WTE community. Boasting a blend of cotton, elastane and nylon, Bombas deliver plenty of stretch and breathability, both of which are crucial during pregnancy. The brand also offers its signature Honeycomb Support System, which gives you a little extra comfort in the arch of your foot.
And don't worry about these socks slipping down your leg. The band at the top is stretchy enough to accommodate swollen calves but tight enough to keep the socks in place.
The sizing, however, may present a challenge. I tried the Bombas compression socks and felt like the medium was too big for my size 8 foot, so I didn’t get the support as I needed. I didn’t try to exchange them for a smaller size (that may very well have worked!), but I gifted them to a relative who found them to be a perfect fit and fell in love. Bombas' socks are a little thick and may not be ideal for summer. In that case, you may want to consider its ankle compression socks.
"I work in healthcare on my feet all day everyday. I have Bombas as well as a lot of other brands. The higher compression Bombas ones are way too tight and I don’t even have big calves lol. The 'everyday' ones are perfect and they’re my go-to compression socks for the OR."
“I tried a bunch during pregnancy and the best ones by far were bombas compression socks. Expensive but very helpful - I still had swelling but on days I didn’t wear the socks, the swelling was significantly worse. Bombas was worth the cost to me because they’re high quality, you don’t have to wash after every use, and they’re an awesome company that does a ton of charitable giving so I didn’t mind spending extra.”
The typical tight fit of compression socks makes them hard to put on, especially if your legs are already swollen or you’re at the stage of pregnancy where bending over is a struggle. TheraMagic’s zippered compression socks might be a little easier to get on because they don’t pull on as tightly. But what sets these apart from other zippered compression socks is the four-way weave that allows for extra stretch, making them even easier to get on.
Of course, there are other features that have earned these compression socks hundreds of five-star reviews. The copper-infused sole helps reduce odor — which is a plus if your feet sweat a lot — and provides additional comfort and support. There’s also a fabric skin guard behind the zipper to prevent potential chafing and irritation. Some reviewers do note, however, that the zipper fabric didn't offer much protection when legs were particularly swollen.
Reviewers love how easy these are to put on and how comfortable they are to wear, especially if you’re traveling for a long period of time. Plus, they have a wide size range, available in sizes up to 5XL.
“I will say not all compression socks are the same. I found ones that looked like the ones the athletes use and they don’t work for me. But the ones I have used when flying with a side zipper work the best for me and really help me not swell during the day. Those are not all fashionable but they work.”
Compression socks can be pricey, especially if you want more than one pair to rotate — but Dr. Motion is an affordable option that expecting moms love. Put simply, these are budget socks that don’t skimp on quality.
These socks offer moderate graduated compression with smooth and breathable fabric, making them easy to wear all day, even in warmer weather. They also come in a striped version and various patterns, though some styles have varying compression levels due to the design, so be sure to check that.
“I have 3 pairs from Target, Dr. Motion brand. The mild compression are great, the medium are so tight they cut off my circulation and leave a nasty red line below the knee. These are the ones I like! The 4-10 fit me and I wear a 9.”
These Kindred Bravely socks are made of premium materials, like bamboo, which makes them more stretchy and comfortable. Plus, the bamboo naturally wicks moisture to keep sweat away and also makes them super soft, making them an absolute dream to wear.
It helps that they don’t look like your typical compression socks — their appearance is a bit more versatile. As someone who wears compression socks every day, I also appreciate that these provide graduated compression; ideal for those who don’t want anything too intense. At $30 for two, they are more affordable than many other comparable options.
Some reviewers note difficulty getting these socks on because they don’t offer much stretch in the calf area. If that’s the case for you, consider opting for the large calf size.
"Kindred bravely compression socks are what I’m wearing, they’re amazing! I wore them on a road trip on the way to our destination, and saw significant improvement than when I didn’t wear them on the trip on the way home."
“I got some off of Amazon from the Kindred Bravely brand for a flight and loved them! It’s a brand specifically for moms/pregnant women and they came in a pack of 2. I had read a ton of reviews for different compression socks that said they were uncomfortable, and these were very comfortable.”
If sweaty feet or temperature regulation are issues, these merino wool-blend compression socks are a fantastic option. The fabrics — USA-grown merino wool, rayon from bamboo, stretch nylon and spandex — work together to wick moisture, reduce odor and keep your feet feeling just right. The graduated compression is perfect for pregnancy-related swelling and fatigue, especially if you’re on your feet a lot.
These socks are soft, breathable and surprisingly non-itchy, which is why so many moms-to-be swear by them for long shifts or travel days. They’re right in the middle of the pack price-wise, and moms say they hold up great, so you can wear them throughout your entire pregnancy and well beyond.
“Sockwell compression socks have held up for me over years of use!! Love them, especially the wool ones! You can also get wide calf or different mmHg levels of compression based on your needs (firm/moderate). I tried some from Amazon and for sure the quality is just not comparable.”
“I’m a nurse and like Sockwell and Bombas. I always go for firm compression myself since my job requires me to be on my feet most hours in the day and I have swelling issues due to an autoimmune disease. Both work really well for me but Sockwell is wool so those typically are better for winter IMO.”
For clocking long hours on your feet, Levsox compression socks deliver firm, consistent support to help reduce swelling and improve circulation throughout the day, which is why healthcare workers and service industry professionals so highly recommend them.
Despite the higher compression level (20-30 mmHg), the fabric feels smooth and breathable — so you can wear them comfortably without getting too hot. Some moms say the snug fit requires a little effort to pull on, but once they’re on, you’re good to go.
Finding compression socks that actually fit wider calves comfortably can be tough, but PRO Compression Marathon compression socks are built with more stretch and a roomier calf design. Yeat they don’t sacrifice compression strength for stretchiness. These are serious socks with firm compression (20–30 mmHg) made for distance runners, but pregnant moms love them for everyday swelling, long work days, exercise and travel. The material is smooth, moisture-wickin, and supportive all the way up the leg. They’re a bit pricier than others (especially if you buy them on Amazon), but there are also ample size options and plenty of colors to choose from, so you can find your perfect fit and style.
“I’ve worn pro compression brand marathon socks for years at work. It’s made massive changes to my leg discomfort and swelling.”
Other Factors to Consider When Buying Compression Socks
Pressure levels: Compression socks come in two main types: graduated and uniform pressure. Graduated compression socks are tighter at the ankle and gradually loosen as they go up the leg, which helps encourage blood flow back toward the heart — great for swelling or varicose veins during pregnancy. Uniform compression applies the same pressure throughout, which can still be helpful but isn’t as supportive for your lower legs. All of the picks on this list offer graduated compression because it delivers unrivaled targeted support for pregnancy symptoms.
Fabrics: The socks featured here are made from blends that often include nylon, spandex, and sometimes cotton, bamboo, wool or polyester. Nylon and spandex offer stretch, structure and durability to help your socks stay snug. Cotton adds softness and breathability, while polyester blends and wool or bamboo tend to be more moisture-wicking, which is great if your feet sweat (thanks again, pregnancy hormones). Some styles also incorporate antimicrobial fibers to help control potential foot odor.
Fit and length:Good compression socks should feel snug but not restrictive. They’ll feel like a firm hug without cutting off your circulation. You want even support without bunching or slipping. My favorites are knee-high, which helps maximize circulation, especially in the lower legs. Compared to compression leggings, knee-length compression socks also avoid adding pressure around your belly, making them a more comfortable choice for all-day wear.
mmHg: An acronym for “millimeters of mercury,” which describes the pressure level. Typically, socks will offer either light (10-15 mmHg or lower), moderate (15-20 mmHg), or firm (20-30 mmHg) compression.

FAQ
What do compression socks do during pregnancy?
During pregnancy, you carry an increased amount of bodily fluid, which can lead to uncomfortable swelling or varicose veins. “The increase in progesterone from pregnancy can cause relaxation of the walls of veins, so the blood pools in the lower body due to gravity,” explains Iffath Hoskins, M.D., an OB-GYN at NYU Langone Health in New York City.
Compression socks are supposed to help these side effects, which is why Dr. Hoskins, along with the American College of Obstetricians and Gynecologists (ACOG), recommends wearing them to relieve swelling, ease leg cramps and help prevent deep vein thrombosis (DVT), a condition that can cause blood clots to form in the deep veins of the leg or other areas of the body. Compression socks might even help with morning sickness. A 2017 study found that wearing compression socks could improve nausea and vomiting during pregnancy.
Do compression socks help with swelling?
As Dr. Hoskins explains, compressions socks essentially massage the muscles to encourage better blood flow throughout the entire body — not just the legs. Science backs this up: a 2022 study found that wearing compression socks during pregnancy led to significantly less swelling in their ankles and calves, prevented varicose veins, and also reduced that achy feeling that can happen.
How long should I wear compression socks?
There’s no time limit on how long you can wear compression socks. Dr. Hoskins recommends putting them on at the beginning of the day, ideally before you experience any swelling, since being swollen can make it harder to get the socks on. “Wear the socks for as long as is comfortable, but especially when walking, standing, or sitting (e.g. whenever your feet and legs are dangling),” she says. If you’re going to be on a plane, put them on before the flight and wear them throughout.
How tight should compression socks be?
Compression socks should be snug enough that they aren’t falling down, but not so tight that you feel them cutting off your circulation (the opposite effect.) Again, this is why you should look for socks that offer mild (10 to 15 mmHg) to moderate (15 to 20 mmHg) compression and are made of nylon or spandex to ensure there’s some give.
Can I sleep in compression socks?
You can sleep in compression socks, but it’s not necessary. Since your legs and feet are at the same level as the rest of your body while you’re sleeping, you’re not likely to experience the same swelling.
How do you wash compression socks?
Though the instructions may differ slightly between pairs, there’s one common rule when washing compression socks: Avoid hot water. The high temperature could result in compression socks shrinking to the point that they’re too tight (or don’t fit at all!). For that reason, it’s also best to let them air dry after washing them on the delicate cycle with cold water or hand washing them.
