When you’re sitting down for any long period of time, whether it’s in-flight, on a train, or even at your desk, your blood flow isn’t at its most efficient. The lack of proper circulation can leave you dealing with discomfort and swollen feet. Enter the compression sock.

As per medical experts, compression socks primarily function by applying gentle pressure to the lower extremities. In many people, but more common in patients over 65 years of age, the veins of the lower extremities do not function properly. The result is pooling of fluid in the lower legs, which can result in infection, blood clots, ulcers, and even limb loss. A good pair of compression socks will gently squeeze your legs to increase pressure in your tissues and reduce leakage in your blood vessels.

Here are some  of the best compression socks for keeping your feet happy.

Tips for Buying Compression Socks

Understand compression levels
Since you’re looking specifically for compression socks, the first thing you want to consider is, compression. Pressure levels are measured in mmHg, which stands for “millimeters of mercury;” according to Vim & Vigr, this originated from the pressure generated by a 1-millimeter-high column of mercury. Yes, it’s a bit obscure. Nowadays the unit of measurement is mostly used to denote things like blood and intracranial pressure in medicine.

The standard level in over-the-counter compression socks is 15-20 mmHg, but a few more intense options offer 20-30 mmHg. Prescription-level socks also come in 20-30 mmHg, 30-40 mmHg, and 40-50 mmHg. Older travellers should consult with a physician to choose their best compression level, but most doctors will recommend 20-30 mmHg, as anything higher than 30 is generally too strong for non-medical use.

Choose the most effective materials
By definition, a compression sock is one that applies some degree of pressure or compression to the lower extremity whereas a normal sock applies minimal to no pressure to the lower extremity. This ability by a compression sock is made possible, in part, by the material that comprises a compression sock. That is, most compression socks are made of breathable and stretchy materials like nylon, lycra and spandex. Conversely, a normal sock usually is made of cotton, cotton blends or polyester that does not have the properties.

Pay careful attention to size
You need your compression socks to fit well. Too small and you risk cutting off circulation, but if you go too large, they won’t actually compress you.
