What You'll Learn

Compression socks are available at some airports
Compression socks are commonly recommended to prevent deep vein thrombosis (DVT) during long flights. DVT-related complications, such as pulmonary embolism, can be deadly. Compression socks squeeze at the ankles, with pressure gradually decreasing further up the leg, helping to keep blood flowing by forcing blood in the legs to return to the heart. However, it is important to ensure that compression socks fit properly, as an incorrect fit can increase the risk of DVT.
In addition to preventing blood clots, compression socks can also improve your running economy and ground stride length, swing time, and heel strike parameters. This can be especially useful when you need to sprint across the airport to catch a connecting flight.
While compression socks are available at some airports, it is generally recommended that you plan ahead and purchase them before your trip. This will allow you to ensure that you get the correct size and type of compression sock for your needs.

Graduated compression socks are best for travel
Compression socks are a great way to reduce swelling and tiredness in your legs when travelling. They are designed to improve blood flow, which can help prevent travel-related blood clots, such as deep vein thrombosis (DVT). Graduated compression socks are tighter at the bottom than the top, which prevents them from cutting off circulation. They are labelled with a compression level range in millimetres of mercury (mmHg) rather than a single number.
Graduated compression socks are ideal for travel as they are designed to provide tailored support. They offer more pressure around the ankle and less in the calf. This helps to boost circulation and retain warmth in the toes. They are also great for running, as they improve your running economy and enhance ground stride length, swing time, and heel strike parameters.
When choosing graduated compression socks, it is important to consider the fabric. A durable, moisture-wicking fabric is ideal, as it will keep your feet dry and comfortable. Some fabrics, such as nylon and spandex, are also easier to pull on and offer more stretch. It is also worth looking for features such as arch support, seamless toe closure, and a turn-welt top to prevent slippage.
You can buy compression socks at the airport, but it is recommended to plan ahead and buy them before your trip. This will ensure you get the correct size and type of compression sock. Incorrect compression or an incorrect fit can do more harm than good and increase your risk of DVT.

Compression socks can help prevent blood clots
While it is possible to buy compression socks at the airport, it is recommended that you plan ahead and purchase them before your trip. This is because it is important to get the correct fit and compression level, and airport vendors may not be able to measure you properly. Incorrect compression or an incorrect fit can do more harm than good and may increase your risk of developing deep vein thrombosis (DVT).
Compression socks are an effective way to prevent blood clots, particularly during long periods of inactivity, such as on a long-haul flight. They work by applying pressure to the lower legs, which stimulates normal blood circulation and helps to prevent blood pooling and blood clot formation. Compression socks also aid in decreasing the diameter of distended veins, which improves valve effectiveness and further reduces venous pressure. This is important because high venous pressure can increase the risk of blood clotting.
In addition to preventing blood clots, compression socks can also help to manage venous disorders such as varicose veins, spider veins, and DVT. They can reduce symptoms such as swelling, pain, itchiness, and heat at the skin level. Compression socks can be especially beneficial for individuals with weakened or damaged vein walls, as they support the veins and ensure blood flows freely, reducing the risk of further vein damage and clotting.
It is important to note that compression socks are not a treatment for existing blood clots. If you have a confirmed DVT, it is recommended to consult a healthcare professional before using compression stockings, as there is a risk that they could dislodge the clot. However, compression socks can be safely used to prevent blood clots from forming and to manage complications after a DVT.

They may not be effective for all travellers
Compression socks are tight-fitting socks that squeeze at the ankles, with pressure gradually decreasing further up the leg. They help boost blood back to your heart, preventing it from pooling in your feet. They are commonly used to prevent deep vein thrombosis (DVT) and pulmonary embolism, which can be deadly.
However, they may not be effective for all travellers. Firstly, incorrect compression or an incorrect fit can do more harm than good. They can increase the risk of DVT and cause skin issues such as chafing or sores, which can lead to infection if not properly cared for. Compression socks are not recommended for individuals with skin that bruises easily or has a compromised skin layer. Additionally, the dry air, cramped conditions, and unpredictable nature of air travel can increase the likelihood of side effects. Discomfort and side effects may appear after a few hours of continuous use.
Furthermore, the risk of developing severe blood clots from flying is relatively low, and it is challenging to determine whether compression socks make a significant difference in preventing blood clots among flyers. The American Society of Hematology guidelines does not recommend compression socks for low-risk travellers on short flights. Instead, they suggest that compression socks be worn on longer flights by individuals at high risk of developing blood clots.
Therefore, while compression socks can be beneficial for some travellers, they may not be necessary or effective for all. It is important to consider individual circumstances, such as medical history and skin sensitivity, when deciding whether to use compression socks during travel.

It's important to get the right fit
Compression socks are specially designed to fit tighter than regular socks, gently squeezing your legs to improve blood flow and reduce pain and swelling. They are particularly useful for those at risk of deep vein thrombosis (DVT) and can be purchased over-the-counter or with a prescription from a doctor.
When selecting compression socks, it is important to get the right fit to ensure they are effective and comfortable. Compression socks come in various lengths and tightness levels, so determining the specific function, type, and compression level you need is essential. For instance, if you are an athlete, you may require a different level of compression than someone who needs the socks for daily wear or during pregnancy.
To find the right size, refer to the size charts provided by the manufacturer. These charts typically list a shoe size range and may include the circumference of your limbs. The calf measurement is the most crucial factor in determining the correct fit, so be sure to measure your calf circumference and match it to the size chart. You can then use your shoe size as a secondary guide.
When putting on compression socks, gather the material from the top cuff to the ankle, fit the sock to your foot, and then pull it up over your calf. The top of the sock should sit just below the crease of your knee. If the sock is too long, slide your thumbs inside the cuff and push the material down to a comfortable height, ensuring it lies flat against your skin without bunching or wrinkling.
Wearing compression socks that are too tight can be uncomfortable and may restrict your movement. They should feel snug but not painfully tight. On the other hand, socks that are too loose will not provide the desired compression benefits. Therefore, it is important to find the right balance and follow the size guide to ensure a proper fit.
