With all the great compression socks available, it can be hard to settle on a single pair. If you are struggling to pick out a pair of compression socks, we can help! This handy guide will tell you about the factors you need to consider when shopping for the best compression socks.

Compression Levels

Any reputable compression sock company should give you the compression levels for the socks. Mild compression is anything between 10 to 15 mmHg while moderate compression is 15 to 20 mmHg. High is anything over 20 mmHg. Generally, mild compression does not do enough to help travelers on flights.

At the same time, extremely high compression is not recommended except for those with medical conditions. Travelers should typically pick moderate compression levels, like that offered by the Trtl Travel Sock, that may prevent blood clots but without being too tight.

Sock Length

Most compression socks are at least mid-calf in height, and some go all the way up to the waist. The studies done on compression socks tend to agree that something knee-high is ideal for travel. It helps prevent deep vein thrombosis and avoids fluid buildup in your lower legs. Higher socks are not dangerous, but they usually are not necessary. They can just make it harder to put on socks and stay cool during travel.


Not all compression socks are made of the same material. The best compression sock material for traveling is always going to be some sort of synthetic blend. Socks made from natural fibers generally are not good at moisture-wicking, so high-quality synthetics provide more comfort. Keep in mind that a common complaint among travelers is that compression socks are hot. Therefore, you might want to avoid heat-trapping polyester and look for lightweight Lycra instead.


For good compression socks for travel, look for features that provide additional comfort. Since you will be wearing them all day, you want something that is not going rub against your skin. 

As you can see, there are all sorts of great features to pick from when shopping for travel socks. To protect your feet while traveling, your main focus just needs to be finding something knee-high with moderate compression. When you choose Trtl Travel Socks, you can stay comfortable and safe on long flights.
