The science of compression
Air compression has been studied for decades. Here’s what the research tells us, and how we’ve built it into Compression and Compression PRO: four overlapping chambers that squeeze from foot to thigh, with up to 250mmHg on PRO.
The evidence
Researchers have studied air pressure around the legs since the 1930s, looking for ways to help blood move through them. The idea of copying the calf muscle pump from the outside goes back more than 50 years.
Sports scientists started looking at it for recovery more recently. That research is younger and smaller, and it grows every year.

How Compression PRO is designed
Your legs have a pump of their own. Every time you walk, your calf muscles squeeze the veins inside them and send blood back up towards your heart. When you sit or rest, that pump goes quiet.
Compression boots work on the same idea from the outside. Four overlapping chambers fill in order, from your foot up to your thigh, then let go, so the squeeze always travels in one direction.
Pressure sensors read every chamber in real time and adjust it to the shape of your leg, so the squeeze stays even from top to bottom.
12 pressure levels
40mmHg, gentle250mmHg, firm
Why pressure matters
Lab studies found a clear, consistent pattern: from 60mmHg up to around 120 to 140mmHg, the higher the pressure, the more blood moved. Compression (up to 200mmHg) and Compression PRO (up to 250mmHg) both reach that range with room to spare, so you can build up to the squeeze that suits you.
Ren et al., 2022 measured blood flow in the skin of the foot in 12 healthy adults. Delis et al., 2000 measured how well the leg veins emptied in healthy legs.
The science
Choose a mode to see how the chambers fill
Sequential pneumatic compression is the scientific name for what the boots do. Air chambers wrap the leg and inflate in order, starting with the one furthest from your heart, then release.
The order is the point. A squeeze that starts at the foot and travels up the leg moves fluid in the same direction your veins already carry it: back towards the heart.
Sequence, the default. Each chamber inflates to your chosen pressure and releases before the next one starts. Short, rolling bursts of compression that never hold one area for long.
Circulation. Chambers fill one after another, foot first, and hold until all four are inflated. Then they release together. The longest, most continuous squeeze of the three.
Combination. Sequence and Circulation in one alternating cycle: a rolling wave, then a full build from foot to thigh, then round again.
Inside your legs
Four steps, from the first chamber filling to the release. Tap a step, or use the arrows.
Why compression
A simple, drug-free way to help your legs feel fresher. Here is what people reach for it for.
4chambers, working from foot to thigh
After a long run, a long shift or a long day on your feet, let the boots work the heaviness out while you put your feet up.
15–60minute sessions
Make it part of your cool-down, so your legs feel ready for the next session sooner.
250mmHg at the top setting
Twelve levels, from a gentle 40mmHg to a firm 250mmHg. Start easy and build up.
3modes to choose from
A slow, rhythmic, massage-like squeeze that makes it easy to sit back and switch off.
+2attachments for Compression PRO
Add the Hip attachment for your glutes, hips and lower back, or the Arm attachment for your shoulders, arms and hands. Same controller, same wave.
Meet Compression PRO
Compression PRO pairs up to 250mmHg of adaptive pressure with four overlapping chambers, in a wireless design you can take anywhere.
Our most powerful compression yet, adjustable across 12 levels from 40mmHg, with a pump built for faster inflation.
Foot, calf, lower thigh and upper thigh. Each one overlaps the next, so the squeeze never stops short.
A touch-screen controller shows live pressure, your timer and the active chamber. No plug needed mid-session.
Add the Hip and Arm attachments to take the same compression beyond your legs.

Summaries of studies and reviews looking at air compression for recovery. Some found clear benefits and some didn’t, so we’ve shown both.
After exercise
Across 17 studies, compression after exercise gave small improvements in muscle function and in how sore people felt. Effects on blood markers of muscle damage were inconsistent.
Maia et al., 2024After a 161km ultramarathon
One 20-minute session after the race lowered how fatigued runners’ muscles felt straight afterwards. It made no difference to soreness or running times over the next week.
Hoffman et al., 2016One session at rest
One hour of compression from foot to hip improved a measure of blood vessel function in both the legs and the arms, compared with a sham session.
Martin et al., 2015Forward splits
Fifteen minutes of compression improved forward-split flexibility more than the same session with the leggings left uninflated.
Sands et al., 2014Results are mixed. Benefits tend to be small and short-lived, and several trials found no difference in next-day strength or performance. The studies used different devices, pressures and session lengths. They did not test Pulsio boots, but help explain the wider research behind air compression.
The studies
Plain-English summaries of the key studies, with links to the original research.
17 studies and 319 people. Small benefits for muscle function and for how sore people felt; mixed results for muscle damage markers.
20 trained men, five daily sessions after hard squat training. Compression kept pain threshold and flexibility from dropping, compared with sham. Strength was no different. Part-funded by a compression device maker.
72 runners after a 161km race. Muscles felt less fatigued straight after a 20-minute session; soreness and running times over the next week were no different.
56 ultramarathon runners, four daily sessions. Fatigue scores were better straight after and on day one, but soreness and running times were no different.
21 trained cyclists. 30 minutes of compression between two rides made no meaningful difference to a 4-minute all-out effort.
20 healthy adults. One hour of foot-to-hip compression improved a measure of blood vessel function in the legs and arms, compared with sham.
Healthy legs, pressures from 60 to 140mmHg. Higher pressure emptied the leg veins more, up to about 120mmHg. 140mmHg was no better than 120mmHg.
9 people, one 15-minute session. Forward-split range improved more with compression than with the leggings left uninflated.

Compression PRO sessions can be set from 15 to 60 minutes, in 5-minute steps. Compression offers 20, 25 or 30 minutes.
Sequence is the default: short, rolling bursts, one chamber at a time. Circulation builds from foot to thigh and holds before releasing. Combination alternates the two. Try each and use the one that feels best.
Start low and build up. The squeeze should feel firm but comfortable. If it ever feels painful, or you get tingling or numbness, lower the pressure or stop.
Air compression is non-invasive and drug-free. Don’t use it if you have, or think you might have, a blood clot (DVT), or over broken skin or a fresh injury.
If you’re pregnant, have a heart or circulation condition or diabetes, or have recently had surgery, check with your GP before using it.
Both have four overlapping chambers, three modes and smart pressure sensing. Compression PRO goes up to 250mmHg across 12 levels, is wireless with up to 3 hours per charge, and works with the Hip and Arm attachments. Compression goes up to 200mmHg, isn’t wireless and doesn’t take the attachments.
Both come in X-Small, Small, Medium and Large, and suit most people between 5’0” and 6’4”. Check the size chart on the product page. If you are between sizes, size down.
Yes. Air compression has been studied for decades, and sports scientists have been testing it for recovery since the 1990s. In sport, studies often find people feel less sore or less fatigued after a session, though the effects are small and not every study agrees. The studies on this page used a range of devices, pressures and session lengths. They did not test Pulsio boots.
