Wearing compression socks can mimic the contraction function of the calf muscles, even if you aren’t walking around, said Dr. Michael Go, an associate professor in the division of vascular diseases and surgery at The Ohio State University Wexner Medical Center. “They are also good at preventing the leg swelling that some people get after a long plane trip,” he added.

Below, we’ve rounded up eight compression socks that reviewers say are ideal for flights. Pick up a pair or two before your next travel day and enjoy flying the in maximum comfort, even if you’re in the last row of the plane.

Promising review: "My husband and I each wore a pair of these magical socks on an international flight. Neither of us had ever worn a compression sock before, so we were skeptical to say the least. At home when we tried them on they were soft and comfy, but we doubted we'd be able to wear them through a whole day of travel. I packed extra socks in our underseat bags assuming we'd have to change socks at some point in the flight. That did not happen! These socks are somehow tight, but also not tight. I don't know how to describe it. The fabric is soft and lightweight. The top of the socks stay in place and after over 12 hours of wearing them we did scoot the tops down just a bit because they were feeling tight, but that is nothing. And after a marathon day of a plane, a train, and multiple automobiles, our legs and feet were in amazing shape! I followed the washing instructions and they washed and air dried with no shrinking or pilling. We followed the measuring instructions and sizing was perfect. These socks are the most comfortable socks we own and we will reach for them even on days we're not traveling." —A.L.A.

Promising reviews: "True compression socks, quality. Bought for long flight 6 months pregnant. Other socks were too extremely tight and impossible to get on, these were perfectly easy to get on and not too tight. I have thinner calves." —Michaela Kazules

"Perfect for travel! Comfy without being itchy or too tight. Holds up well to washing." —Lindsay D.

"I purchased the socks because I was recommended to wear compression socks while on our international flight. My husband and I went on our baby moon at 26 weeks pregnant. I put them on right before boarding and wore them the entire flight. I was nervous at first because I typically don't wear compression socks so I was worried that they would be a little tight. They were fine for me, I did measure my calf and go off the measurements that they recommended. I was between buying the wide or just the regular I ordered both to see which ones felt better. The wide ones actually did not get in in time, so I ended up just sticking with the regular and they were fine. Quality compression socks!" —Kristen Brooke

Promising reviews: "I work as a deckhand on a boat and got these to help with leg/foot pain I was experiencing at the end of my shift. The first day wearing these was like night and day - after hours on my feet, my legs weren't swollen and my feet didn't hurt nearly as much. Washed them in cold water and let air-dry and they're still in good shape. Great socks for a great price." —Brenda L.

"Bought for long-haul airline travel and they've been great." —Alfred S.

Promising reviews: "Really made a difference on a 7 hour flight to London. After a 3 hour layover, I put them on when just before I boarded not knowing if I would like them or not. I only suffer from mild leg pain. Had no leg pain whatsoever. I'll never do a long flight again without them. They just helped me to relax a bit more, as you never really know what kind of leg room you're going to get on the plane. Great quality. Good purchase." —Paris

"Worked perfect for flying. I could put them on myself and they were comfortable. I sprained my ankle while on vacation and had to wrap my foot. We managed to get the sock over the wrap to fly home. My swelling was minimal." —Diane Pope

Promising reviews: "I wasn’t sure if compression socks were for me (they always seemed like something only older people wore), but the Bluemaple 6-Pack Copper Compression Socks changed my mind. The fun and colorful designs made them feel way more modern and wearable, and honestly, I get compliments on them! I’ve worn these on about five flights since buying them, including a couple of long-haul trips, and they’ve held up well. They stay comfortable for hours, don’t slip down, and really help reduce that heavy leg feeling you sometimes get during travel. They’re easy to wash. I’ve thrown them in with different cycles, and they still come out looking and feeling great. With six pairs in a pack, it’s a no-brainer for anyone prepping for a trip. I even gifted a couple to friends for international flights. If you’re traveling internationally, sitting for long periods, or just want your legs to feel better at the end of the day, these are 100% worth it. Stylish, durable, and functional." —RJ

In previous reporting, Dr. Scott N. Hurlbert, a vascular surgeon in Colorado Springs, Colorado, explained, “When you are traveling by air, you usually don’t have much room to move around. As a result, the blood becomes more stagnant, which can lead to blood clots.” Between that and dehydration, flying may increase your risk of developing a type of blood clot called deep vein thrombosis, or DVT.

I often swell up on flights, and have found that compression socks make a huge difference not only in how my legs look, but how I feel. I can walk through large airports and scurry between connecting flights and still feel energized. They’ve been a total game-changer. I wear them religiously anytime I am on a flight that is longer than four hours, but have also found myself popping them on for shorter flights and road trips for extra comfort.
