How to buy the best compression socks for running and sports

There are a few important things to consider before buying a pair of compression socks. Not least of which is what they actually are and how they work. 

The idea of compression socks is that they act as an extra layer of protection on the body, applying pressure to specific areas to help the return of blood back to the heart. This allegedly has the side-effect of lowering lactic acid production and even increasing VO2 max.

What does that mean for us? Well, in addition to making your lower legs look extra colourful, compression socks make blood flow more efficiently – it's the same reason people wear them during flights, to help prevent DVT (or deep vein thrombosis).

Most socks apply what we call gradient pressure, which means less pressure is applied to the leg the higher up you get. However, because different people have different shaped legs and feet, as well as different levels of circulation, you need to look for socks that apply pressure at the right level, to the areas that are going to help you. 

The level of compression varies too. If a brand lists the grade of compression (rated in mmHg) it’s a good sign you’re getting real compression rather than something that’s just a bit tighter. Many brands don’t provide this information

You’ll find a range of different fabrics. Some will combine compression with thermal layering to keep your feet warm, others use moisture wicking technology to do the opposite.  So it’s important to think about when and where you’re most likely to use them. 

It’s also worth thinking about thickness and how they’re going to feel in your running shoes. All the compression in the world won’t help you if you’ve got blisters because your shoe-sock combo has eaten up all the wiggle room for your toes.

To get the best fit, measure your calf circumference at its widest, you will need this number (in either centimetres or inches) to find the best fitting compression sock for your legs.

• Buy the Rockay Vigor Graduated Compression Socks directly from Rockay

If you care about the planet as much as your feet, you should get Rockay socks. The Rockay Vigor, for example, not only applies ample amount of pressure in all the right areas (graduated compression 16-23 mmHg) but it's also made using Econyl Regenerated Nylon yarns. These yarns are made of recycled ocean plastic and therefore super sustainable.

Another technology is used in the Rockay Vigor Compression Socks to aid sustainability: the Polygiene treated socks need less washing as long as they are laid out to dry in between use. Polygiene absorbs odour-causing bacteria and as long as the socks are dry, it will do it's job. Less washing = more environmentally friendly socks.

The Rockay Vigor Graduated Compression Socks' compression level is on the tight side, but not in a bad way. They are also on the high side of the scale so the socks run all the way up to knee-high. Despite offering loads of compression, the Vigor still has breathable mesh zones for extra breathability. These socks really have it all.
