Shin splints: causes, recognition, and what compression can do

Shin splints are among the most common complaints of runners. A nagging pain along your shins that flares up as soon as you start logging miles, and has the annoying tendency to return as soon as you resume your training. In this article, you’ll read what shin splints are, how to recognize them, and how you can help prevent their recurrence.

What are shin splints?

Shin splints is the common name for medial tibial stress syndrome, an overuse injury of the shin bone. The pain is located along the inner-back side of your shin, spread over an area of several centimeters. It’s not a marginal phenomenon: among groups of runners and military personnel, the incidence is around 35 percent, and in one study among female marine recruits, even 53 percent experienced it during basic training.

Justin, physiotherapist and co-founder of KINEX, explains how it starts: “Usually insidious. A nagging, diffuse pain along the inner-back side of the shin. Initially, you feel it when you start, and it subsides as you warm up. If it worsens, it also lingers after training.”

One distinction is important: “If the pain is very sharp and localized to a single small point, that’s more indicative of a stress fracture. You’ll want to get that assessed.” A diffuse, sensitive area is typical of shin splints; a sharp point is a warning sign.

Who is at risk?

A large meta-analysis by Hamstra-Wright and colleagues (British Journal of Sports Medicine, 2015), which compiled 21 studies, identified several factors that increase the risk of shin splints: a higher BMI, a greater navicular drop (a measure of a fallen arch), more mobility in ankle plantarflexion and hip external rotation, and female gender. A later meta-analysis by Winters and colleagues (Sports Medicine, 2017) added a telling factor: a previous episode of shin splints.

The latter is crucial. Those who have experienced it once are clearly more vulnerable to recurrence. This is precisely why preventing its return is at least as important as addressing it the first time. An interesting detail from the same study: limited dorsiflexion and knee alignment turn out to be NOT risk factors, even though they are often mentioned.

The common denominator in practice is immediately apparent to Justin: “Too much, too soon. The volume or intensity increases too quickly, and the body doesn’t get time to adapt.” Additionally, footwear, running surface, and running technique play a role. “It’s rarely one thing. You always look at the overall picture of load and recovery.” This aligns with how you approach tired, heavy legs.

What to do during an acute episode

Are you currently experiencing pain? Then the approach starts with the cause: reduce your load and gradually build back up. Justin: “Pain that increases during running, persists afterward, or changes your running pattern. In such cases, continuing to train is unwise.” And be honest with yourself: a sock won’t cure an acute shin splint. Research also confirms this. In the only randomized study on the treatment of shin splints in athletes, Moen and colleagues (2012) divided 74 athletes into three groups: a progressive running schedule, the same schedule with stretching and strengthening exercises, and the same schedule with a sports compression sock. The recovery time did not differ significantly between the groups; all three took an average of about three to four months. The message is clear: in an acute episode, rest and a sensible build-up are the true drivers of recovery, not the sock itself.

Where compression does make a difference: preventing recurrence

Here lies the true value of compression for shin splints. Not as a quick fix for an acute injury, but as support to prevent symptoms from returning as you rebuild.

The mechanism is logical and substantiated. With each foot strike, your tissue vibrates briefly, and these muscle vibrations create repetitive traction on the periosteum of the shin bone, precisely the area that becomes overloaded with shin splints. That compression reduces these vibrations is one of its most proven effects. The large meta-analysis by Wang and colleagues (Journal of Sport and Health Science, 2025), which compiled 51 studies, found a clear, significant reduction in these tissue vibrations. Fewer vibrations mean less repetitive traction on a sensitive area.

And that translates into practice. In a study of over five hundred athletes by Franke, Backx, and Huisstede (BMC Sports Science, Medicine and Rehabilitation, 2021), runners who consistently wore compression socks had a significantly lower chance of recurring lower leg injuries, with an odds ratio of 0.32. This is observational research, so not conclusive proof of cause and effect, and managing your load remains the foundation. But the combination of a plausible mechanism and these practical data makes compression as support for protecting your training rhythm highly defensible.

Maarten, co-founder of KINEX, recognizes this precisely: “For me, it was on the inside of my ankles, extending up to my calves, especially if I ran too many miles too quickly again. Once I built up sensibly and started wearing compression, I could maintain my rhythm much better. The most important advantage for me was that I didn’t constantly have to stop again due to the same complaint.”

Smart build-up with support

The combination makes the difference: a gradual build-up as the foundation, and firm, controlled compression that supports your lower leg and dampens vibrations as you build up your mileage again. This is what KINEX’s class 2 compression is designed for: noticeable enough to support the lower leg, and controlled measurement so you know what pressure you’re getting. What length suits you can be found in short vs long compression socks, and you can find the right size via what size compression socks do I need.

When to see a professional?

Justin: “If the pain persists or worsens despite rest and adjustments, shifts to a single sharp point, or you can no longer walk normally, get it assessed. You want to rule out a stress fracture.”

Conclusion

An acute shin splint is resolved with rest, a smart build-up, and attention to the cause; a sock won’t cure it, and we don’t claim it will. But as soon as you start rebuilding and want to prevent the complaint from recurring, compression becomes a valuable ally. It demonstrably dampens the muscle vibrations that stress the shin bone, and athletes who wear it consistently experience fewer recurring lower leg complaints. For those familiar with shin splints, that’s the difference between constantly having to stop and being able to keep training.

Perseverance pays off. Build up smart, support your legs, and keep going.
