what do compression socks do on flights


Are you one of those people who dread the discomfort and potential health risks associated with long flights? If so, you’re not alone. Many travelers experience swelling, fatigue, and even the risk of blood clots during air travel. However, there is a simple solution to these problems: compression socks. In this article, I will explore the benefits of wearing compression socks on flights and how they can make your travel experience more comfortable and safer.

Understanding Compression Socks

Compression socks are specially designed stockings that apply gentle pressure to your legs, ankles, and feet. They are commonly used to improve circulation, reduce swelling, and prevent blood clots. The pressure exerted by compression socks helps to keep the blood flowing efficiently, which can be particularly beneficial during long periods of immobility, such as during a flight.

How Do Compression Socks Work?

Compression socks work by applying graduated pressure to the legs, with the highest pressure at the ankle and gradually decreasing as it moves up the leg. This helps to promote blood flow back to the heart, preventing it from pooling in the lower extremities. By improving circulation, compression socks can reduce the risk of blood clots, known as deep vein thrombosis (DVT), which can be a serious concern during long flights.

Benefits of Wearing Compression Socks on Flights

Now that we understand how compression socks work, let’s explore the specific benefits they offer for air travel:

Reduced Swelling

One of the most common complaints of air travelers is swelling in the legs and feet. Prolonged sitting and reduced movement can lead to a build-up of fluid in the lower extremities, causing uncomfortable swelling. Compression socks can help to alleviate this problem by promoting better blood flow and preventing fluid retention.

Improved Circulation

Long flights can lead to reduced circulation in the legs, which can increase the risk of blood clots. Compression socks help to counteract this by maintaining proper blood flow, reducing the risk of DVT and other circulation-related issues.

Reduced Leg Fatigue

Sitting for long periods in cramped airplane seats can lead to stiffness and fatigue in the legs. Compression socks provide support and stability to the muscles, reducing fatigue and discomfort during the flight.

Prevention of Blood Clots

One of the most serious risks of air travel is the development of blood clots, particularly in the legs. Compression socks can significantly reduce this risk by ensuring that blood is circulating effectively and not pooling in the lower extremities.

Comfort and Support

Aside from the medical benefits, many travelers find that compression socks simply make their flight experience more comfortable. The snug fit and gentle pressure provide a sense of support and security, reducing overall discomfort during long hours in the air.

Choosing the Right Compression Socks

When selecting compression socks for your next flight, there are a few important factors to consider:

Compression Level

Compression socks come in different levels of pressure, usually measured in millimeters of mercury (mmHg). For air travel, it is recommended to choose socks with a compression level of 15-20 mmHg, as this provides adequate support without being too constrictive.

Proper Fit

It’s crucial to ensure that your compression socks fit properly to be effective. They should be snug but not overly tight, and should extend from your toes to just below the knee for maximum benefit.

Material and Comfort

Look for compression socks made from breathable, moisture-wicking materials to ensure comfort during your flight. Consider features such as padded soles and seamless toes for added comfort during long hours of wear.


As a frequent flyer myself, I can attest to the effectiveness of compression socks in making air travel more comfortable and safe. The benefits of reduced swelling, improved circulation, and prevention of blood clots make them an essential item for anyone spending extended periods in the air. By choosing the right compression socks and wearing them during your next flight, you can ensure a more pleasant and worry-free travel experience.


1. Are compression socks suitable for everyone?

Compression socks are generally safe for most people, but individuals with certain medical conditions should consult with a healthcare professional before using them, especially those with diabetes or circulatory disorders.

2. Can I wear compression socks during the entire flight?

Yes, it is safe and beneficial to wear compression socks for the duration of your flight, as they can help to prevent swelling, fatigue, and blood clots that may result from prolonged sitting.

3. Can I wear compression socks with sandals or open-toed shoes?

While it is possible to wear compression socks with sandals or open-toed shoes, it is generally best to pair them with closed-toe footwear to maximize their benefits and ensure a proper fit.

4. How do I know what size of compression socks to buy?

To determine the right size of compression socks, you should measure your ankles, calves, and the length of your legs to find the appropriate size according to the manufacturer’s sizing guidelines.

5. Can I wear compression socks for other forms of travel, such as long car rides or train journeys?

Absolutely, compression socks can be beneficial for any form of travel that involves prolonged sitting or immobility, including car trips and train journeys. They can help to reduce swelling and fatigue in the legs and promote better circulation overall.
