Compression garments have become nearly as common in the running world as water bottles and GPS watches. From knee-high socks to full-length tights, these snug-fitting garments promise to boost performance, improve recovery, and even prevent injury. But are they worth the hype—or just another fitness fad?
Let’s unpack the research, the real-life benefits, the pros and cons of wearing compression gear while running and if they are worth the price.
What Are Compression Garments, Exactly?
Compression garments are tight-fitting clothing designed to apply graduated pressure to specific areas of the body, typically the limbs. The pressure is usually highest at the extremities (like the ankle) and decreases as it moves up the limb. Some compression garments give a specific pressure applied (in mmHG) but most are not so specific and advise the athlete they should be snug but not restrictive. This design is meant to help improve blood flow, venous return, and lymphatic drainage, all of which can contribute to performance and recovery benefits.
Popular types of compression wear for runners include:
- Calf sleeves
- Compression socks
- Compression shorts or tights
- Arm sleeves
Side note- there are also arm sleeves that are meant to be an easy form of temperature control but do not apply pressure. The purpose of these less compressive sleeves is to roll up when starting to run and then to have the option to dissipate heat more easily with them rolled down if conditions change or the athlete is too warm.
What the Science Says
1. Performance During Running
The evidence here is mixed. Some studies show small improvements in running economy (how efficiently you use oxygen), muscle oscillation control, and proprioception (body awareness), especially during long-distance efforts. Other studies, however, show no significant changes in VO₂ max, speed, or time trial performance. Compression garments may offer minor improvements in endurance events, likely through reduced muscle vibration and improved comfort—but they’re not a magic bullet for speed. And even in the studies showing positive effects, they are small, suggesting their use is really more of a marginal gain.
2. Recovery After Running
This is where compression garments really SHINE! Research supports their ability to:
- Reduce muscle soreness (DOMS)
- Minimize swelling
- Speed up recovery of muscle strength and power
Mechanisms behind these effects may include better venous return, reduced inflammation, and improved oxygen delivery to muscles. Wearing compression garments after running, especially long runs or races, is more strongly supported by research than wearing them during activity. Additionally if an athlete is traveling a significant distance for a race, such as a long car or plane ride, compression garments can be a game changer with reduction of swelling from stagnant fluid and can protect against blood clots during periods of prolonged immobility. Athletes who are predisposed to clotting, female athletes using birth control and other vulnerable populations should be encouraged to use compression garments during these events, both pre and post race.
3. Injury Prevention
There’s no strong evidence that compression gear can prevent injuries. That said, some runners report a perceived sense of stability and support—especially in the calves and thighs—which may help reduce strain or overuse in certain situations. Note that these anecdotal compliments are related to soft tissue structures and not joints. Compression garments should not be used as a substitute for bracing if it is warranted. Your weekend warrior basketball player showing up for a pick-up game in two knee sleeves is doing nothing for the stability of his patella. The bottom line is compression garments can be used as a tool for comfort, but not as a replacement for proper training, strength work, or gait correction.
Should You Use Them?
Compression garments won’t turn a 6-hour marathon into a Boston Qualifier, but they can be a useful part of your running toolkit. They’re especially valuable for:
- Recovery days
- Traveling to or from events
- Managing chronic muscle soreness or swelling
If you’re curious, try them out on a training run or post-run to enhance recovery. Like any tool, it’s about how you use it—and whether it works for your body.
🏃♀️ Final Thoughts
Compression gear isn’t essential, but it isn’t snake oil either. For many runners, especially endurance athletes, it can provide modest benefits in comfort, recovery, and muscle control. As with any intervention, listen to your body, monitor how you feel, and think of it as a supplement to smart training, not a substitute.
