Finding the right pair of compression socks can help improve circulation and reduce the risk of some vein-related conditions. (Vim & Vigr, Feetures)
Compression socks are a type of specialized sock designed to help improve circulation in your lower extremities, encouraging blood and fluid movement back toward your heart. They're tighter than your average pair of Hanes, and for good reason: High-quality compression socks may help reduce symptoms of lymphedema and edema and reduce vein-related clotting emergencies, including deep vein thrombosis (DVT) and pulmonary embolism. Compression socks can also help ease the discomfort of chronic venous insufficiency, a common blood pooling disorder that increases your risk of pulmonary embolism.
"Chronic venous insufficiency is when the valves in the [legs'] veins have stopped working," says Dr. Kristy Golden, a podiatric surgeon at Kaiser Permanente in Maryland. "Compression socks act like an external fluid circulation management system, almost like an external vein."
That said, companies make lots of claims regarding the potential benefits of compression socks, some of which aren't totally accurate. That's why we decided to test some of the best compression socks to really figure out which pairs are worth purchasing. Considering that even the most expensive compression socks typically cost less than $50 a pair, you may get a lot of benefit from purchasing such a humble piece of clothing.
In our quest to find the best of the best, we tested and researched 16 pairs of self-proclaimed compression socks from brands like Bombas, Copper Compression and Vim & Vigr. We wore them for multiple days and during a variety of activities (walking, running errands, jogging and hiking) to get a true feel for what each one could do. We also spoke to two physical therapists and several doctors to better understand the science of compression socks, how they impact your heart and foot health, along with any health benefits or dangers we should look out for.
Update, July 22, 2025: We checked all product prices and availability. We added an option for "best for pregnancy." Our picks for the best compression socks remain unchanged.
Cost: $38 | Compression level (mm Hg): 15-20 mm Hg | Material: Cotton, nylon, spandex | Sizes: Small/medium, medium/large, large/XL; also available in sizes for large calves | Length: Knee-high
If you're looking for a true compression sock to help with blood circulation and to combat swelling and fatigue, it's important to find a knee-high pair with graduated compression measured in mm Hg (or millimeters of mercury) — the same unit used to measure blood pressure. All of Vim & Vigr's compression socks are listed with the Food and Drug Administration and are developed in conjunction with vascular surgeons to ensure they meet the standards necessary to be considered everyday or medical-grade compression socks.
These knee-high options provide a 15-20 mm Hg level of compression that's considered "mild-moderate" and is suitable for everyday wear. Our tester said they were great to throw on the day after a tough workout to help encourage recovery and reduce soreness, especially on days she had to sit at her computer for most of the day — she felt less swelling in her feet and ankles and less stiffness overall. She did warn that they're a little tough to get on (thanks to that verifiable compression level), but once they were on, they didn't feel overly restrictive.
They're also available in a wide range of styles and sizes, including those designed for wide calves.
Cost: $54 | Compression level (mm Hg): 30-40 mm Hg | Material: Cotton, nylon, spandex | Sizes: Small/medium, medium/large, large/XL; additional options for wide calves | Length: Knee-high
To be clear, not everyone needs medical-grade compression socks. These socks are specifically indicated for individuals who are at risk for moderate edema, lymphedema, DVT, chronic venous insufficiency (CVI) and blood clots. In fact, unless you have a recommendation or a prescription from your doctor to use this level of 30-40 mm Hg compression, you shouldn't buy these socks. They're hard to get on, and they really put the squeeze on your calves.
"The first treatment [of CVI] if symptoms occur is the usage of compression stockings that compress the superficial veins and improve the blood flow to the heart by pushing the blood into the deep venous system, and by thus, swelling and symptoms are reduced," said Dr. Ernst von Schwarz, a triple board-certified cardiologist.
That said, if you are in need of medical-grade compression, Vim & Vigr delivers. And while its socks are spendy ($54 per pair), they're actually FSA and HSA eligible for reimbursement, which is a nice feature. The brand also offers the socks in multiple styles and extended sizes, including for those with wide calves.
Though the tight squeeze of the socks is particularly noticeable at the feet and ankles (where the graduated compression is the highest), they still feel comfortable at the calf. While our tester isn't in need of medical-grade compression, reviewers on the Vim & Vigr website noted that they're helpful for post-surgery recovery, DVT and POTS. "The support is absolutely AMAZING!!! When I am not feeling my best with my condition of POTS (Postural Orthostatic Tachycardia Syndrome) this is the pair I wear. The higher gauge of 30-40 truly helps my condition. I can stay on my feet longer," noted one reviewer.
Cost: $29 | Compression level (mm Hg): 8-15 mm Hg | Material: Bamboo, recycled polyester, recycled nylon, spandex | Sizes: Small, medium, large | Length: Knee-high
If you have a long day of travel ahead of you, especially a flight that's expected to last more than six hours, chances are you could use a pair of travel-friendly compression socks. Hours spent sitting without getting up and moving around increase the risk of emergent conditions like DVT and pulmonary embolism. While drinking plenty of water, getting up and walking around and stretching your legs can all help reduce the risk, compression socks can also help.
These bamboo compression socks from Ostrichpillow offer a mild level of compression (8-15 mm Hg) that's appropriate for people who don't have other risk factors for DVT (in which case, a higher level of compression might be needed — make sure you ask your doctor). They're comfortable, breathable and are naturally odor-resistant, so you don't have to worry about your feet smelling when you take your shoes off at airport security.
Our tester wore them while driving for six hours, then walking around an event for another three hours. She found them to be "like a second skin" — she didn't even feel like she was wearing socks. She also said she wore them with a pair of boots that sometimes rub and cause blisters, but these socks kept her protected from any irritation or pain.
Cost: $45 | Compression level (mm Hg): 20-25 mm Hg | Material: Nylon, cotton and elastane | Sizes: Small, medium 1, medium 2, large 1, large 2, XL | Length: Knee-high
There's some evidence that compression socks can help improve performance and post-workout recovery during and following exercise, and some compression socks were made just for this purpose.
"Compression socks do not offer any specific athletic benefits, but they do improve the blood flow in the lower extremities, which can aid in decreasing swelling, which allows a joint to move more efficiently," says Carneal Owens II, a sports physical therapist in Chicago.
2XU is a performance sports brand, and these socks are designed to be worn on days of activity. While that certainly applies to athletic endeavors, including running, hiking, cycling and team sports, they're also helpful for days when you know you'll be running around all day, playing the "sport" of life. While not much research has been done on what level of compression is most beneficial for sport or exercise performance, one 2020 review study found that most effects are seen with socks between 20 and 30 mm Hg — offering support for the potential benefits of these 2XU socks given their 20-25 mm Hg rating.
Our tester found these compression socks from 2XU to be some of the best for day-to-night wear. She pulled these knee-length socks on in the morning, went through the workday, ran some errands and took a walk in the evening. Upon taking them off at night, she noticed a couple of impressive pros. For one, they followed through on their promise of being a good option for those who deal with swelling during the day — our tester's feet tend to do just that after a long day. While they didn't prevent all swelling, especially on a humid summer day, there was a notable difference.
She also noted that they were breathable and light, likely because they're made with 25% nylon. She also liked that there were a wide range of sizes. She ended up with the M1 size, but the brand also considers calf and shoe sizes in its size chart.
Cost: $29 | Compression level (mmHg): 20-30mmHg | Material: Olefin, nylon, spandex | Sizes: Small, medium, large, XL | Length: knee-high
There's actually quite a bit of evidence that wearing high-quality compression socks after a tough workout can help reduce muscle swelling and markers of muscle fatigue, aiding in postworkout recovery. Some people even report less soreness after wearing compression socks following exercise, but that may be a placebo effect, as clinical markers of delayed onset muscle soreness don't appear to be affected by wearing such garments.
Cost: $10 | Compression level (mm Hg): 8-15 mm Hg | Material: Nylon, acrylic, cotton and spandex | Sizes: 1 size only to fit sizes 4 to 10 | Length: Knee-high
Our tester tried out these Dr. Motion knee-high compression socks and was totally tickled by the mini hearts design. She could see herself integrating them into different outfits on days when she wants an extra boost of support through the calves.
However, they're pretty low on compression at just 8-15 mm Hg, so she didn't notice a big change in circulation or muscle fatigue, as the brand promises. That said, her calves felt more supported by the knee-high design, and her ankles were a tad less swollen than if she had worn regular noncompression socks.
Her main qualm is that there's only one size available. These socks are said to fit women's shoe sizes 4 to 10, and, at a size 8, she felt that they fit decently well in the foot department but were harder to pull on over her calves. The one-size-fits-all approach also means that the compression level is unlikely to remain standard from person to person, so it's likely not the best choice if you're in need of a higher level of support.
That said, at just $10 a pair (or $40 for six pairs if you're buying on Amazon), these socks are a lot more affordable than some of the others on this list. If you want a little extra support for day-to-day life without paying through the nose, these socks just might do the trick.
Cost: $26 for a 3-pack (about $8.60/pair) | Compression level (mm Hg): Not stated | Material: Copper-infused nylon and spandex | Sizes: Small, medium or large | Length: Ankle
The Copper Compression Powerknit Ankle Sport Socks were hands down our favorite pair of ankle-height compression socks for all-day wear. Our tester wore them for two full workdays, during which he was either on his feet or driving from 8:30 a.m. to 4:30 p.m. Both days, he found them super comfortable thanks to the thick nylon/spandex material, while the moisture-wicking promises actually delivered. He shared that he normally sweats a fair amount, especially in the summertime heat, and these socks managed to prevent any swelling or odor.
Generally speaking, true compression socks provide the mm Hg graduated compression ratings and offer greater benefits when they reach calf or thigh height. That said, ankle compression socks can still improve and support circulation through the foot, and for individuals who haven't been prescribed a specific level of compression by a doctor, this may end up being sufficient (and often more comfortable) for everyday use and activity.
While these ankle socks don't offer the mm Hg rating, our tester found them to be pretty tight, which compression socks should be, and ranked them high for fit, comfort, range of motion and support. "Normally, I feel like my socks don't really last, and these feel like they'll last a while," he says. "I would definitely pick them over the usual brands I wear, and I plan to keep using them going forward."
As a bonus, these Copper Compression socks have a lower price tag than a few of the other brands we tested. At about $8.60 per pair, our tester gave them top ranks for value as well.
Cost: $25 for a 2-pack ($12.50/pair) | Compression level (mm Hg): 20 mm Hg | Material: Nylon and spandex | Sizes: XS, small/medium, large/XL | Length: Ankle
Most ankle-height compression socks don't offer an mm Hg rating (see all of the other ankle socks we tested for this article), but these trainers from Pro Compression are the exception to the rule. With a moderate compression rating of 20 mm Hg, they're a good option for runners or athletes who want the added support for their feet without the bulk or heat of a calf or knee-high sock.
Our tester noted that her feet felt encased (but not squeezed) by these socks and that they felt supportive and comfortable during her longer runs. She also specifically said she would pick these over any of the other socks she tested for outdoor workouts because she can't stand wearing knee-high socks when she's exercising in the heat.
Cost: $29 | Compression level (mm Hg): 20-30 mm Hg | Material: Olefin, nylon, spandex | Sizes: Small, medium, large, XL | Length: Knee-high
There's actually quite a bit of evidence that wearing high-quality compression socks after a tough workout can help reduce muscle swelling and markers of muscle fatigue, aiding in post-workout recovery. Some people even report less soreness after wearing compression socks following exercise, but that may be a placebo effect, as clinical markers of delayed onset muscle soreness don't appear to be affected by wearing such garments.
The point is, if you're training hard for an event and you're looking for a way to speed recovery between workouts, compression socks like this pair from Swiftwick just might be worth investing in. The 20-30 mm Hg compression rating is particularly helpful in supporting your muscles and veins post-workout, encouraging circulation and blood flow. Our tester said that despite the tight nature of the socks, they were still comfortable and breathable — she didn't feel like they were cutting off circulation or making her feet go numb. She wore them during and following an especially hard run and felt that she was ready to go again the next day, even though it was a preplanned rest day.
Cost: $34 | Compression level (mm Hg): 15-20 mm Hg | Material: Nylon and spandex | Sizes: Small, medium, large, or x-large, wide calf | Length: Calf
Compression socks are useful in preventing swelling and varicose veins during pregnancy and easing some third-trimester fluid retention in the legs.
"Swelling in the legs and feet is common during pregnancy, especially in the later stages. This happens because your body retains more fluid, and the growing uterus puts pressure on the veins that carry blood back to your heart," says Dr. Lauren Demosthenes, an ob-gyn and senior medical director of Babyscripts. "This pressure can slow blood return and lead to fluid buildup. Hormonal changes may also contribute."
Dr. Greg Marchand, a dual board-certified ob-gyn, recommends knee-high or thigh-high graduated compression socks with 15-20 mm Hg for milder swelling or 20-30 mm Hg of compression for pregnant patients with varicose veins.
Comrad's nylon compression socks have been a fan favorite among many pregnant folks online, with a strong 4.4-star rating on Amazon. Customers from 11 to 39 weeks pregnant have shared how much they love these compression socks for everything from travel to everyday wear to ease discomfort, though some shorter customers aren't happy with the length, indicating they're too long for shorter legs.
There are several types of compression socks available, so it's important to understand the differences.
Graduated compression socks: This type of compression garment provides the most pressure at the ankle, which gradually decreases between the ankle and the knee or thigh, depending on the height of the sock. Doctors often prescribe graduated compression socks for individuals with venous disease or edema to help support circulation and to prevent the pooling of fluid at the ankles, but any socks with mm Hg pressure ratings from mild to firm fall into this category.
Anti-embolism stockings: Used to reduce the risk of deep vein thrombosis (DVT), a blood clot that forms in the leg, these stockings typically stretch from the foot to the thighs, although sometimes there are knee-high options. They're typically prescribed for individuals who are confined to bed, especially post-surgery, or as treatment for specific conditions. Similar to graduated compression socks, they offer targeted compression to improve blood flow and prevent clots.
"Compression" socks or nonmedical compression hosiery: Because the word compression isn't regulated, any brand can add "compression" to its marketing language as a way to promote its socks. And to be fair, these products are typically tighter and offer greater support than options that don't use compression-related language. That said, they may not provide any verifiable level of pressure (as measured in mm Hg), so they wouldn't be appropriate to rely on if you're in need of a specific level of pressure for health conditions, pregnancy or athletic performance.
Before adding those socks to your cart, there are a few things to consider. First and foremost: compression. The appropriate level varies according to personal needs, whether for a medical condition or other uses. Nonmedical support hosiery typically has low compression of 8-15 mm Hg (appropriate for all-day, everyday wear), while prescription medical socks can reach much higher levels of 3050 mm Hg.
If you have a medical condition or concern, seek advice from a medical professional to determine what level of compression is best for you. Otherwise, here's a quick guide:
Low compression (8-15 mm Hg): Recommended for mild symptoms like achiness, tired muscles, minor swelling or discomfort from long periods of sitting or standing. Low compression is also appropriate for traveling, particularly if you don't have risk factors for DVT.
Moderate compression (15-20 mm Hg): Suitable for moderate swelling, preventing varicose veins during pregnancy and long flights.
Firm compression (20-30 mm Hg): Used for severe swelling or recovery from some surgeries to prevent blood clots. May also be ideal for sports performance and recovery.
Extra-firm compression (30-40 mm Hg): Entering medical-grade territory, these may be prescribed for conditions like varicose veins, chronic venous insufficiency or DVT.
Medical-grade compression (40-50 mm Hg): Typically prescribed for serious medical conditions like lymphedema (severe swelling caused by lymph fluid buildup) and chronic venous disorders.
Other factors to think about include:
Length: Compression socks come in various lengths, such as ankle, crew, knee- and thigh-high socks. Each provides different support levels, with full-length socks being the most supportive, cradling the foot, ankle and calf.
Material: Some options are made from breathable, moisture-wicking fabrics to reduce moisture and odors, while others feature tighter materials for optimal compression. Consider your primary needs before choosing.
Style and color: Compression socks come in all the colors of the rainbow, from fun and funky to neutral hues like black, white and gray. There are many patterns too. Choose a pair you'll consistently wear; if you don't usually opt for bold prints, stick to something plainer.
Fit: These socks should be snug but not uncomfortably tight. Most options have a decent size range, but always check the sizing guide before purchasing. An ill-fitting pair may not be effective or comfortable.
Intended use: Each pair of compression socks is designed for specific uses, such as all-day wear, sports, pregnancy, travel or foot and ankle pain. Determine what you need them for, even if it's just daily support to reduce swelling and fatigue.
Price and brand reputation: Ensure the socks fit your budget, especially if you plan to buy more later. All featured brands are known for quality and customer satisfaction, but if exploring other options, consider brand reputation as well.
When choosing the best compression socks, we relied on research and at-home testing. We consulted Milica McDowell, a doctor of physical therapy, certified exercise physiologist and VP of operations at Gait Happens, an online platform for foot education. After she explained the technical aspects of compression socks, we tested and researched 16 pairs from brands like Bombas, Copper Compression, Vim & Vigr and Feetures.
Here's the testing process:
Daily wear: Each pair was worn for at least one full day, from morning to night.
Observations: Throughout the day, we noted fit, material, feel and comfort.
Shoe compatibility: We wore comfortable shoes that were neither too tight nor too loose to avoid impacting the feel of the socks.
Product claims: After a full day of wear, we compared our experience with the product descriptions, considering claims about breathability and muscle fatigue.
Other factors: We also evaluated targeted compression, sensory stimulation and impact protection.
While compression socks have plenty of benefits, they are not a cure-all for several health conditions. "If there is pain in the calf muscle and you have varicose veins or leg swelling, it's really important to be evaluated by a doctor to make sure that you don't have a blood clot," says Golden. It's also key to get properly fitted for compression socks if you're dealing with a serious condition like lymphedema or chronic venous insufficiency.
If you're pregnant and dealing with sudden severe foot swelling, Marchand recommends seeing a doctor as soon as possible, as this could be a sign of DVT or another serious condition. "Persistent swelling that doesn't improve with rest, elevation or compression socks, or swelling accompanied by symptoms such as high blood pressure, headache, vision changes or pain in one leg, should be discussed with your ob-gyn," says Marchand.
Generally speaking, unless you have a medical condition and have been prescribed a certain level of compression by a physician, most folks should stay under 20 mm Hg, McDowell says. She also notes that you'll definitely know if your pair is too tight: "You could experience cramping or numbness and tingling, like when your foot falls asleep."
If you have any doubts about your socks being too tight, you should probably ditch them and opt for something a bit less compressive. However, if you're unsure about the compression level you need, you can always seek professional advice from your doctor.
Most websites have a sizing guide you can refer to. Many brands recommend sizing up rather than down if you're between sizes; however, for greater compression, you may prefer to size down. You may also want to measure the circumference of your calves in addition to your shoe size to determine whether you need to find compression socks sized for wider calves.
McDowell explains that the optimal wear time for compression socks varies. Typically, they're beneficial for 30 minutes to a few hours.
The duration also depends on the reason you're wearing them. For instance, people recovering from a high-impact run may want to wear them for the first few hours after getting home, while those wearing them for pregnancy or travel can keep them on for the entire day as long as they fit comfortably.
Golden recommends putting on your compression socks first thing in the morning before any swelling fluid has time to settle in your lower legs, and taking them off before bed for more comfortable fluid control.
According to Cleveland Clinic, you can wear compression socks while sleeping. However, this may be unnecessary. This is especially true for anyone with venous issues and ulcers who may need to air their skin at night.
McDowell notes that compression socks have many benefits: "[They can help] improve circulation, improve recovery from sports or work, [help you] get ready faster for your next sport or work session, improve proprioception and balance and even provide feelings of safety and comfort."
"Regular socks don't have a prescribed amount of squeeze (compression), and they're sewn on a circular loom," McDowell says. "Regular socks also stretch horizontally, while compression socks are designed to stretch vertically."
Road Runner R-Gear CEP Compression Light Cushion No-Show Socks: While our testers liked that each sock had its own designated "L" or "R" for the left and right feet, these felt way too tight despite being the right size. At the end of the day, they felt like they made our testers' feet swell even more, plus they're pricey at $45 for a three-pack.
Bombas Travel Compression Sock: We love that Bombas has a compression sock specifically designed for flying (with a 15-20 mm Hg rating), and this two-pack set comes with a "gripper slipper" too for relaxing after a long day of traveling. Our tester noted that the socks were comfortable and supportive, but she couldn't test them for a flight and, at $78 for the set, wasn't sure their value lived up to the price.
Bombas Performance Compression Ankle Socks: While described as offering compression and "strong support," they don't provide an actual mm Hg rating, so it's unclear exactly how much compression is being provided. Our tester noted the socks felt thick and tight but still breathable and comfortable during walking. While they certainly make a high-quality athletic sock, they didn't quite make the cut when looking at all the other options.
Feetures Elite Light Cushion Mini Crew: Feetures makes some of the best athletic socks around, and its left foot/right foot designs offer a near unbeatable fit. We liked the style of these mini crew compression socks, and our tester loved how comfortable they felt during a run, but as with the Bombas Performance ankle socks, there's no stated mm Hg of compression, which reduced our confidence regarding the compression claims.
Sheec ComFits Compression Aqua-X AeroDri No Show Blister Tab Socks: There's no denying that these are comfortable, foot-hugging socks that perform well during exercise. That said, they're not as compressive as the other options tested, and they don't provide any information regarding the mm Hg rating, so their verifiable compressive benefits are less clear.
Sheec ComFits Compression Aqua-X Quarter Socks: As with the other Sheec model, our tester liked these for their athletic performance — they're comfortable, quick-drying and mold to the foot without restricting movement or rubbing. And yet they don't provide any real information about their compressive properties, so they didn't quite make the cut.
Pro Compression Marathon Recovery: As much as our tester loved the Pro Compression ankle socks, she didn't like the recovery socks. While stronger compression can be beneficial for recovery, she felt the 25-35 mm Hg was just too tight, cutting off her circulation and leaving her feeling uncomfortable.
