We’ve all been there, stepping off a long flight and looking down to find our ankles slightly puffier than we remember. Whether you call it cankles or just plain swelling, it’s one of the less glamorous side effects of air travel. But here’s something that frequent flyers, cabin crew, and even celebs swear by: compression socks. You might have seen them on travel influencers or in your dad’s drawer, but make no mistake: These socks are having a moment. But the big question is: Do compression socks really help with ankle swelling during flights? The short answer? Yes, they do and here’s why.
Why Do Our Ankles Swell On Planes?
Let’s break it down. When you’re sitting still for long periods like during a flight, your blood flow slows down, especially in the lower legs. At high altitudes, the cabin pressure and lower oxygen levels can cause fluid to pool in your feet and ankles. Add in dehydration (because airplane air is super dry), and you’ve got the perfect recipe for puffy ankles. This kind of swelling, called flight-related edema, is usually harmless but definitely uncomfortable and not the most stylish way to arrive at your destination.
So, how do compression socks help?
Compression socks are specially designed to gently squeeze your legs, encouraging better blood flow from your feet back to your heart. Think of them as a little workout for your veins. They apply the most pressure at your ankles and gradually loosen as they move up your legs. By keeping your blood circulating and preventing fluid from pooling, compression socks can reduce or even completely prevent ankle and foot swelling during flights. Plus, they can help reduce the risk of something more serious: deep vein thrombosis (DVT) a blood clot that can form in the legs during long-haul travel.
Are they comfortable?
Surprisingly, yes! Today’s compression socks aren’t just medical-grade and boring. Many brands now offer super cute designs from sleek neutrals to fun prints that look more like fashion-forward knee-highs than something your grandma would wear. They come in various pressure levels too, so you can pick one that feels just right for your needs. Look for styles with 15–20 mmHg pressure for travel use enough to keep swelling at bay without feeling too tight. Compression socks are a smart choice for anyone on a flight longer than four hours, especially if you:
– Have poor circulation
– Are pregnant
– Have a history of DVT
– Are taking birth control or hormone treatments
– Are simply prone to swelling or leg fatigue
Even if you’re none of the above, wearing a pair can make a long-haul flight feel way more comfortable.
