Compression socks work wonders in treating and preventing the swelling and pain in the feet that plague pregnant women. Through a snug fit, gentle pressure, and lower leg support, compression socks increase blood flow and reduce swelling in your calves, ankles, and feet. Compression socks may also help reduce dizziness associated with nausea and vomiting when worn during early pregnancy.
When shopping for compression socks, Salma Aziz, a podiatrist with Mississippi DPM, says: If you are pregnant, start with light pressure. 15 to 20 millimeters of mercury (mmHg). This is the same measurement scale used for blood pressure and indicates the level of compression in different parts of the sock.
In addition to speaking with two board-certified podiatrists and a physician about what pregnant people should look out for with compression socks. Our editors tested 26 different pairs When sitting or standing for long periods at home or at work. During the testing period, I kept the socks on and paid close attention to the fit, feel, support, and how my feet felt after wearing them.
Should I wear compression socks during pregnancy?
Throughout the pregnancy process, your body produces and circulates about 45% more blood than it did before pregnancy. This is because the heart is working harder to meet the needs of the placenta and organs. You also retain more water during pregnancy, which can cause swelling in your feet, ankles, and feet. Compression socks increase circulation and reduce symptoms of increased blood volume and fluid retention..
“During my pregnancy, I realized the benefits of wearing compression socks,” says Dr. Aziz. “It relieves swelling, reduces leg pain, and can also help prevent varicose veins and blood clots. However, pregnant women don’t necessarily need to worry about blood clots unless their doctor tells them they’re at risk.”
Swelling is normal during pregnancy, but a sudden increase can be a sign of pre-eclampsia, a potentially dangerous complication characterized by high blood pressure. If you are concerned about swelling, consult your doctor immediately.
Why I liked it
These socks not only feel great, but they also look great. What I liked during the test was snug and smooth I fell in love with the wide variety of cute patterns that blend into our skin. Our personal favorites are the navy socks with a red fox on them (pictured below), which we even received compliments on when we wore them.
Unlike other compression socks, Levsox was easy to put on and did not irritate the skin at the collar. They were snug yet flexible, almost like wearing leggings and felt like they were massaging my arches and heels a bit.
But please be careful
Although only knee-length, the Levsox still offers great value. I was happy with the price range, but was pleasantly surprised. Multiple pairs per order. Another pleasant surprise is that the socks last a long time after being washed and dried, making them a practical option for those who wear them frequently.

Compression socks should last a long time. During testing, we found that Sockwell compression socks are of high quality and the fabric wears well. I also love that it shows no signs of shrinkage or pilling no matter how many times I wash it.
It was difficult to wear these socks at first because of the high compression level. A tutorial on the Sockwell website helped me figure it out. Once they were snugly in place, I immediately noticed: The fabric is soft and breathable, so I didn’t have to worry about my feet getting sweaty.. We also love the blend of merino wool and bamboo, which is a sustainable material and helps regulate body temperature.
But please be careful
One of our editors wore these socks for hours at a time to improve symptoms associated with an autoimmune disease. They felt relatively tight, but I liked that they didn’t slide down my feet and fit securely without constricting. After wearing the socks for a full day, she said her feet felt great and the circulation in her feet had improved significantly.

The editor who tested Bombas Everyday Compression Socks was used to wearing his own socks due to a medical condition. She knows a lot about compression socks, and these bombas are Perfect fit and hugged her feet and legs in all the right places. The opening of the shoes felt tight, but I was able to move my feet freely while wearing them, which alleviated foot fatigue.
True to Bombas fashion, these compression socks are made from high-quality materials. I love that they resemble retro tube socks and have unique and stylish details. They cost $28 per pair, but I think they’re worth it for the fit, fabric, and effectiveness.

Comrad’s warm, soft and incredibly cozy socks are a combination of a slipper and a compression sock. To test them out, I wore them frequently over a few weeks and they were so comfortable that I even slept in them.
Surprisingly, these socks feel like they’re made from organic materials, even though they’re mostly nylon or polyester. The soft fabric feels good on your feet, kept us warm Even in winter, it will last a long time no matter how many times you wash it.
But please be careful
These socks provided a pleasant feeling of pressure on the soles of my feet, but the level of compression was not much different from regular knee-high socks. The compression level is considered the lightest, so it didn’t have much support and didn’t have the power to promote blood circulation in the legs. However, I can definitely say that they are the most comfortable socks I have ever worn. Highly recommended for those who work from home and only need socks. light compression.

Although this Lululemon sock is designed specifically for runners, we found it beneficial for many forms of exercise. Whether running, walking or spinning, these socks provided ankle support, reducing leg fatigue and improving overall performance.
It is unclear what the pressure level of this sock is. Lululemon is advertised as “light” compression but does not offer measurements in mmHg. In our opinion, the compression level of these socks is Feels like a firm hug Around the calf, heel, arch, and top of the foot. I could feel that specific areas of support, such as the molded knit heel, allowed for proper movement during exercise. It also had a soothing massage effect, so I also wore it while recovering after exercise.
But please be careful
If I could change anything about these socks, it would be the toe seam. I found myself having to adjust my socks a lot during workouts to keep the seams from irritating my toes. But these socks have held up through many miles, dozens of Peloton sessions, and several washers and dryers, so I think the $38 price tag is well worth it.

Our testing process
We spoke to two podiatrists to find out more about the benefits of wearing compression socks and what shoppers should look out for when purchasing. To determine which compression socks make the list, our editors tested 26 different pairs of compression socks at home and at work.
Editors looked at your feet and legs while wearing the socks, including how they felt and whether they felt less swollen at the end of the day. They wore socks when standing or sitting for hours at a time and made sure to wash them after each use. At the end of the testing period, our editors rated each sock on fit, feel, support, and value to narrow down the list.
In addition to testing compression socks, we spent months researching their uses and benefits. During this process, we discovered claims that certain fabrics used in compression socks can expose users to bisphenol A (BPA), a harmful chemical found in plastic. To clarify these claims, we consulted a doctor.
our experts
We spoke to two podiatrists to get some insight into what features you should look for in your pregnancy compression socks and how they can help you. We also spoke to gynecologists about certain fabrics and whether they contain chemicals that could be harmful to pregnant women. The experts we spoke to include:
- Diana Levin Valencia, DPM, Board Certified Podiatrist
- Salma Aziz, DPM, MS, Board Certified Podiatrist, Diplomate Fellow of the American Board of Podiatric Surgery
- Jeanne Conry, MD, PhD, former president of the American College of Obstetricians and Gynecologists, current president and CEO of the Environmental Health Leadership Foundation, and president of the International Federation of Obstetrics and Gynecology (FIGO)
Compression level: what’s the difference?
There are two types of compression socks: uniform (or non-graded) and graduated. Uniform compression socks have the same pressure level throughout the sock, while graduated compression socks have a different range of pressure. This range is divided into two parts, with higher pressure from the feet and lower pressure from the knees.
Uniform compression socks are intended for people who are bedridden, such as patients who have just had surgery. Graduated compression socks are designed for people who can sit and stand. Veins help pump blood upward toward the heart and prevent blood and fluid from collecting in the lower legs, ankles, and feet.
Graduated compression socks come in five levels.
- Light compression (8-15 mmHg): Ideal for mild pain and swelling caused by sitting or standing for long periods of time.
- Class 1 compression (15-20 mmHg): It’s great for preventing fluid buildup and is the most common level available over the counter. According to Dr. Aziz, the optimal level for pregnant people is 15 to 20 mmHg.
- Class 2 compression (20-30 mmHg): Great for preventing varicose veins and venous insufficiency, a condition in which the veins cannot efficiently return blood to the heart.
- Class 3 compression (30-40 mmHg): Ideal for people with chronic venous insufficiency.
- Class 4 compression (40-50 mmHg): It is ideal for treating lymphedema, a condition in which lymph nodes and blood vessels become swollen due to blockage or damage.
How much compression do I need during pregnancy?
“The average slope of compression stockings is 15 to 20 mmHg, which is moderate,” says Dr. Aziz. “In general, this is the appropriate level for pregnant women to wear. Anything tighter than this may cause adverse effects.”
Factors to consider when wearing compression socks during pregnancy
fabric
Compression socks are usually made from mixed fabrics, primarily consisting of elastane (spandex or lycra), nylon, or polyester. Elastane is a synthetic fiber that can stretch up to 500% of its original shape and can withstand this process over and over again until it wears out. It is also extremely durable and highly resistant to body oils, sweat, and detergents. Elastane is the main ingredient that helps tight-fitting compression socks elongate your legs.
Nylon is also a type of synthetic fiber that gives elastic stockings their stretch. Known for its lightness, it is often used in stockings, tights, yoga pants, etc. The third type of synthetic material, polyester, is known for its strength and durability, making compression socks quick-drying.
fit and comfort
Fit is an important factor in deciding whether to continue wearing compression socks. Compression socks that are too tight can actually have negative effects on your body, such as by restricting blood circulation.
In order to wear compression socks for any meaningful amount of time, they must feel comfortable and secure. Depending on your needs, you may experience reduced swelling, pain, and pressure in your legs, ankles, and feet.
Are compression socks safe during pregnancy?
Compression socks are a safe, non-invasive way to reduce swelling and pain in your legs, ankles, and feet during pregnancy. While you may not want to wear them all day every day, Dr. Aziz suggests that the length of time you wear them depends on the individual and their activity level.
“The best time for pregnant women to wear compression stockings is first thing in the morning,” says Dr. Aziz. “You should first elevate your feet to reduce swelling, then put on shoes. You should listen to your body while wearing socks. If you feel discomfort, it’s a good idea to take off your socks, elevate your feet, and then put them back on when the swelling subsides.”
Do socks contain BPA?
In 2022, the Center for Environmental Health (CEH), a California-based activist organization, detected levels of bisphenol A (BPA) in socks from more than 100 popular brands that exceeded state-permitted levels.
BPA is used as an additive in certain synthetic materials such as polyester and spandex, which are commonly used in socks. BPA is a known endocrine disruptor. In children, it can interfere with the development of the nervous system, affect behavioral development, and lead to childhood obesity. However, the Centers for Disease Control and Prevention (CDC) says more research is needed to confirm BPA’s negative health effects, and the science on how BPA absorbs through the skin is not yet established.
Despite CEH’s warnings, no recalls have been carried out, and no other independent or government agencies have confirmed the findings. If you want to avoid polyester or spandex as a safety precaution, look for options made from cotton or other natural fibers.
According to Dr. Conley, “Compression socks are a very important means of treating circulatory problems during pregnancy, especially pain and varicose veins. The benefits of their use outweigh the small theoretical risks of BPA exposure.”
