How do compression socks work?
“Compression socks are tightest at the ankle and gradually decrease in pressure up the leg,” explains Dr Sam Bhide, clinical director at PhysioZen. “By compressing the superficial veins, arteries and muscles, they help improve blood circulation, enhancing overall vascular health,” she adds.
According to Dr Bhide, they can help to improve blood circulation, reduce swelling, reduce the risk of blood clots and deep vein thrombosis (DVT), and alleviate symptoms for those with varicose veins.
Who should use compression socks?
Dr Bhide says compression socks are particularly helpful for:
- Individuals with varicose veins, oedema (a build-up of fluid in the body) or chronic venous insufficiency (which occurs when your leg veins have been damaged)
- People recovering from surgery or injury
- Pregnant women, due to the increase in water weight
- People who are bed-bound or those with limited mobility
- Frequent travellers on long flights
- Workers who stand or sit for prolonged periods
Please note that you should always consult your GP before trying compression socks to make sure they're appropriate for you. You'll find more detail on how to find the best level of compression for your needs below.
Why should I wear a compression sock while flying?
During flights, especially long-haul, prolonged sitting can restrict blood flow in the legs, increasing the risk of swelling and DVT. “Compression socks for flying help mitigate these risks by enhancing circulation, reducing leg and ankle swelling, and lowering the chances of blood clots,” says Dr Bhide.
She recommends also wearing “loose fitting clothes, so the knee-high compression socks can apply the optimum pressure on the legs. Ideally, wear compression socks before boarding and keep them on throughout the flight duration.”
If you find compression socks uncomfortable, you should stop wearing them.
How we choose the best compression socks
We spoke to the experts and researched all the market-leading brands to find the best compression socks for women that cater to different needs, from thigh high stockings for full-leg compression to compression socks for runners. We've also tried many of the brands below ourselves, for running, recovery and travelling.
These are the ones we’ll be putting on before taking off.
Foot health specialist brand, Scholl, is always one of our first ports of call for its science-based solutions. These compression socks are an affordable option designed to be worn in place of normal socks while travelling. They're available in a discreet black or sheer colourway, if you can't wait to put your new holiday shorts on.
The brand says they're clinically proven to prevent deep vein thrombosis, which can be caused by long periods of sitting and restricted movement on long-haul flights. The pack includes detailed information on how to use them, but in a nutshell, be sure to pull them up to just below the knee.

What do compression socks do for you?
Compression socks use medical-grade, elasticated compression fabric to apply gentle, graduated pressure to the lower legs and ankles. This helps increase blood flow and stops fluid from building up in these areas, easing swelling and discomfort and supporting key muscles.
What to look for when shopping for the best compression socks
✔️ A good fit: For compression socks to work properly, you need to make sure the sock lies flat and smooth across your foot and calf. Avoid socks that bunch up because they won’t be able to provide the intended, even pressure. Some options also offer sizes based on both your shoe size and the circumference of the widest part of your calf, which can help with fit.
Users who often find their compression socks rolling down their legs, moving around or not providing enough pressure — especially those with thicker or thinner calves — may benefit from taller, thigh-high compression socks or compression tights. For most users, the knee-high length is ideal.
✔️ Sock type: Most compression socks are available at a knee-length height to provide graduated compression from the ankle throughout the calf.
While you'll see more and more compression sleeves or ankle socks on the market, these don't cover the foot, so they could potentially impede blood flow and cause swelling in the feet for users intending to treat symptoms in the lower legs. Ankle compression socks also can't offer the same compression for the calves and aren't ideal for those trying to help alleviate swelling or cramping.
✔️ Materials: Synthetic fibres, such as nylon or polyester, are the most common materials for compression socks, thanks to their durability and moisture-wicking properties. But these can vary due to the construction of the sock.
Wool, a natural fibre, is inherently moisture-wicking and temperature-regulating, and merino wool is a variety of wool known for its soft feel, making it a great option for compression socks.
Some brands will also use cotton, a popular fabric worldwide that's prized for its breathability, but isn't moisture-wicking.
How to find the right level compression socks
Most compression socks offer graduated compression, which means that the pressure is greatest near the ankle and gradually decreases up the leg; therefore, the pressure of the socks is listed as a range.
Compression levels are measured in millimetres of mercury (mmHg), and the larger the number, the higher the compression.
- 8–15 mmHg or 15–20 mmHg are low compression, great for flying, pregnancy or just general improved circulation.
- 20–30mmHg is most commonly prescribed by physicians and can help soothe a variety of mild conditions.
- 30–50mmHg should only be used when prescribed by a doctor.
For compression socks to work properly, make sure they fit well. The sock should lie flat and smooth across your foot and calf without bunching to apply proper, even pressure.
How many hours should I wear compression socks?
How long you should wear compression socks for really depends on what you’re wearing them for. For general wear, the NHS recommends putting them on first thing in the morning and taking them off for bed, so generally for around 8-10 hours. If you’re new to wearing compression socks, it’s worth wearing them for short periods at a time to begin with so you can get used to them.
Compression socks are designed to be worn when you’re sitting or standing for prolonged periods, and it's recommended that you remove them at night when your legs are elevated, helping to reduce swelling.
If you’re wearing them for a flight, you should put them on before departing and for the duration. If you can, it’s beneficial to get up and move around a few times during the flight too. If you’re unsure about how to use compression socks, or whether they’re suitable for you, we advise speaking to your doctor before travelling.
What brand of compression socks is the best?
This really depends on your needs. If you’re worried about getting swollen legs when you fly, start with Scholl’s Flight Socks, which offer medium levels of compression and help prevent swelling and deep vein thrombosis. If you’re looking for something that covers the whole leg, choose Beister Thigh High Compression Stockings. And if you're worried about swollen legs or ankles during workouts, the Stox Energy Compression Socks or Decathlon’s Compression Socks both help with muscle recovery and inflammation.
What compression socks do most doctors recommend?
A doctor is likely to recommend the highest level of compression (30–50 mmHg) only if you have conditions in which your legs show significant swelling, such as severe oedema and chronic venous insufficiency, or if compression may be appropriate to help prevent deep vein thrombosis (DVT).
"Higher-strength compression tends to be used when there is an established clinical need rather than simply for everyday tired legs. The exact pressure recommended will depend on the condition being treated and the individual’s circulation," says Dr Punam Krishan, an NHS GP and ambassador for Stannah.
"Persistent swelling, swelling that doesn’t improve overnight, skin changes or discolouration, or pitting oedema, where pressing a finger into the swollen area leaves an indentation, are all reasons to seek medical advice rather than simply buying a stronger pair of compression socks.
She adds there are several possible causes of persistent leg swelling, so it’s important to establish what’s causing it and make sure stronger compression is safe and appropriate.
"Reduced mobility can contribute to problems with circulation too, so it can also be an opportunity to have a wider conversation with your GP or healthcare professional about mobility and what additional support might be helpful at home.”
