What Is Compression Gear? How It Helps Runners Perform and Recover

If you’ve spent any time around running communities in the past few years, you’ve probably seen runners wearing tight socks, sleeves, or leggings that look more structured than standard running kit. What you’ve seen is compression gear - and it’s become an essential part of many runners’ kits.

Compression clothing is designed to apply controlled pressure to specific muscle groups. In theory, this supports circulation, improves muscle efficiency, and supports post-run recovery. While it’s not essential to get the best out of your run, it can make a big difference to how you feel during and after a session. Here, we’ll take a look at how compression gear helps runners to perform and recover, explain how to use compression gear properly, and hopefully help you to work out whether or not compression gear is for you.

As a general rule, compression gear is items like socks, tights, sleeves, leggings, and tops that fit closely against the body and ‘compress’ the muscles. The aim is to apply consistent pressure that helps muscle support during exercise. Runners use compression gear for a variety of reasons, including the following:

• It gives a more ‘secure’ feel on longer runs

• It helps with the ‘heavy legs’ feeling that some suffer from post-run

• It can help to keep muscle movements controlled and efficient, which in turn conserves energy

• It can boost blood flow to targeted muscle groups, which is great for both performance and recovery

How does compression gear work?

Compression gear works by applying graduated pressure to areas of the body. This pressure influences the circulatory system and muscle tissue in a few key ways:

1. It can help push blood back towards the heart, which is especially useful for the lower extremities, such as the calves and feet.

2. It limits excessive muscle oscillation - i.e. the small amount of ‘joggling’ movement that happens when your foot hits the ground. This helps to conserve energy.

3. It boosts sensory feedback, making you more aware of how your body moves. This can help you gain more control over your stride, balance, and so on.

Performance benefits and muscle recovery: What the evidence says

It sounds good - but does compression gear actually work? And, if so, what are the main benefits? Let’s take a look at what the evidence says:

Reduced muscle vibration

Compression really can limit how much your muscles move or vibrate with each step. Over time, ‘joggling’ can have a surprisingly high impact on your muscle fatigue and energy budget, so limiting unnecessary muscle vibration is a great way to improve muscle efficiency and slash energy expenditure

Reduction in leg ‘heaviness’

Many runners report that compression helps their legs to feel less ‘heavy’ during and after runs. It’s likely that this is due to both the reduced muscle vibration mentioned above and the ability of compression gear to move blood and excess fluid out of the limbs and back towards the heart and lymph nodes.

Improved post-run recovery

There is strong evidence that compression has significant recovery benefits after exercise.

Wearing compression gear post-run can help reduce muscle soreness and speed up recovery after an arduous training session.

Circulation support

The state of your circulatory system can make or break both your run and your recovery time. Compression gear is great for assisting blood flow, particularly in the feet and calves, which in turn boosts your overall circulation and helps you to run faster for longer. This is one of the main reasons why runners use compression socks.

Consistency over time

Many runners find that wearing compression gear for every run helps them to maintain consistency in their training. This is due to a combination of all the benefits listed above - faster recovery time, better performance, reduced fatigue, and generally better comfort levels during and after the run. All of this encourages people to stick to a running schedule and reduces issues (such as sore muscles) that can derail a training plan.

Types of compression clothing and compression wear

Compression shirts

Compression shirts, as the name suggests, hug the upper body. They’re particularly useful if you have loose skin or are a bit larger, as they can reduce excess movement around your belly, upper arms, and so on. Female runners may also find them a useful addition to a sports bra, for added structure and stability.

Compression shorts

Compression shorts support your glutes, hips, and upper quads. They’re ideal for runs in warmer weather, during which you might not want the extra coverage of compression tights or leggings.

Compression tights

Compression tights cover your whole legs. They’re useful for colder runs, and great if you want some extra compression for your calves, hams, and quads. If you suffer from ‘heavy legs’ during and after runs, these are a good way to keep your legs feeling lighter and fresher for longer.

Compression socks

Compression socks add extra structure and stability to your feet and calves (depending on the length). They’re a good idea if your feet tend to swell after long runs, as they can help to push extra fluid back up your legs to be flushed out by the lymphatic system. 

Compression sleeves

Compression ‘sleeves’ aren’t just for your arms. They’re essentially compression tubes that you can apply wherever needed (typically the calves, knees, and upper arms - but there is a versatile range of sleeve options available to cover all needs).

How to choose the right compression gear

To get the full range of benefits from your compression gear, it’s vital that you choose well. Here’s what to look for when shopping for compression kit:

Getting the right fit (tight vs restrictive)

Compression gear should feel snug and supportive, not restrictive and uncomfortable. You should notice pressure, but it should not limit your movement, cut into you, or cause discomfort during a run.

Choosing the right material

Ideally, look for specialised fabrics that wick moisture away from your body and retain their shape during prolonged movement and exercise. A good piece should also retain its compression level over repeated washes and plenty of wear.

Matching gear to your running goals

When picking out compression gear, think about when you plan to use it and what you want to achieve. For example, you might pick a pair of socks for recovery, tights for winter runs, or sleeves for targeted support of problem muscle groups.

How tight should compression gear be for running?

How tight is too tight for compression gear? This is a tricky question, as you do need a degree of pressure in order to feel the benefits - and it can be hard to distinguish between ‘effectively snug’ and ‘too restrictive’ when first trying the gear on. You need to run with it for some time to really understand the difference between ‘pressure’ and ‘restriction’.

Obviously, it’s not generally possible to run around with compression gear before purchase, so there is a scale that can help you work out the compression level you’re looking for: the mmHg scale. 

mmHg refers to millimetres of mercury (the same metric that’s used for blood pressure). Most running gear falls between 10 and 20 mmHg, which is generally considered ‘light to moderate compression’. Higher levels, like 20 to 30 mmHg and above, are generally reserved for medical settings (for example, to reduce oedema in the feet and to help with circulatory conditions). As a general rule, you won’t need more than 20 mmHg for training or recovery.

You may also see the term ‘graduated compression’ used for things like socks and sleeves. This means that pressure is tighter around your joint (usually the ankle or wrist) and tapers into lighter pressure as the garment rises up your leg or arm.

How long does compression gear last? (And when to replace it)

Good compression gear should last you throughout a running season, but this depends on how often you wear it, how often you wash it, and how much it stretches. All compression garments will gradually lose elasticity and pressure over time, but high-quality compression gear should hold its form through months of rigorous training.

As a general rule, if you find that your compression garments are feeling looser, or if they can’t hold their shape as well as they used to, it’s probably time to replace them.

When should runners wear compression gear?

When you wear compression gear depends a lot on what you want to gain from it. For example, if you want to improve your running performance on the track, put it on before a run and use it throughout the course. If you want it to speed up recovery, pull on your compression gear directly after a run and wear it for as long as you feel comfortable through the recovery period. 

Many runners wear compression gear on long-distance runs, or even apply it in the later stages of marathons and half-marathons, as legs can swell and get more fatigued over prolonged distances. 

Is compression gear worth it for runners?

Compression gear is not essential for runners, but it can be very useful for comfort, performance, and recovery. While you’re unlikely to see dramatic improvements in your speed or stamina the first time you wear compression gear, wearing it consistently over time can speed up your recovery, improve your form, and generally boost your running performance. 

Ultimately, whether compression gear is worth it for you depends on what you want to get from your running kit. If you don’t like the feeling of extra pressure on your limbs, compression gear is probably not for you. But for those who find the pressure useful, compression gear really can bring tangible benefits to any run or post-run recovery.

FAQs about compression gear for runners

Does compression gear actually work for running?

Yes, compression gear can improve performance, comfort, and recovery when used consistently - but it’s important to note that it’s not a ‘magic bullet’. You’re unlikely to see dramatic results the moment you pull on some compression sleeves, but the benefits do add up over longer distances and timescales.

Is it better to wear compression gear during or after a run?

This depends on what you want to get from your compression gear. Wearing compression during a run can improve comfort, reduce fatigue, and help with circulation - all of which will boost your performance. Wearing compression after a run can help to target muscle groups that need extra help recovering, resulting in faster recovery times and greater post-run comfort.

Do elite runners use compression gear?

Yes, many elite runners use compression gear - particularly for recovery. However, it’s not universal for elite runners. Whether to wear compression gear is a personal choice at every level.

How tight should compression gear be?

Compression gear should add noticeable pressure to your limbs, but shouldn’t be so tight that it restricts your movement or cuts into your flesh. Look for a compression of between 10 and 20 mmHg.

Can you wear compression gear all day?

Yes, but pay attention to how it feels. If your compression gear starts to feel too tight or restrictive, take it off.

Does compression gear help prevent injuries?

Compression gear is more for targeted muscle aid and circulatory support, but there is some evidence that it can help with injury prevention in certain circumstances - particularly ankle injuries. This is largely because it provides additional support to the ankle and gives the runner greater awareness of and control over their gait.

Are compression socks worth it for runners?

Compression socks are one of the most popular pieces of specialised running kit, and can really help with long-term running performance and recovery. Whether or not they’re worth it for you depends on your running goals, what you’re struggling with, and your overall running style.

How long should you wear compression gear after running?

Most runners who wear compression gear for post-run recovery wear it for a few hours after the run. However, you should always remove it if it starts to feel too tight.

What’s the difference between compression and normal sportswear?

Compression gear applies consistent, targeted pressure to joints and muscle groups, while ‘normal’ sportswear focuses more on things like ease of movement and temperature control. As a general rule, ‘normal’ sportswear is looser and less specialised than compression gear.
