Shin splints are caused by repetitive stress on your shinbone and the tissue surrounding it, and stopping them requires addressing the root causes: training load, running mechanics, and lower leg strength. The good news is that most runners can resolve shin splints without stopping running entirely, as long as they make specific, targeted changes.
The medical term is medial tibial stress syndrome (MTSS). What’s actually happening is a combination of two things: muscles in your calf pull on the membrane covering your shinbone (the periosteum), irritating it, and the repetitive impact of running creates tiny microcracks in the bone’s outer layer. The pain typically shows up along the inner edge of your shin, about two-thirds of the way down toward your ankle. Understanding these mechanisms matters because the fixes target each one directly.
Increase Your Cadence by 5 to 10 Percent
This is the single most impactful change you can make to your running form. Cadence, the number of steps you take per minute, directly controls how hard each foot strike hits the ground. A modest increase of 5 to 10 percent shortens your stride, reduces the vertical impact force on each step, and lowers the loading rate on your tibia. Research published in Cureus found that runners with cadences at or below about 166 steps per minute had roughly six to seven times the risk of tibial injury compared to those running at 178 or higher.
You don’t need to overhaul your stride overnight. Count your current steps per minute during a normal run (most GPS watches track this automatically), then aim to add 8 to 15 steps per minute over the course of several weeks. A metronome app set to your target cadence can help you internalize the rhythm. The goal is shorter, quicker steps rather than long, reaching strides. This also reduces peak impact at the knee by about 20 percent, which is a bonus if you have joint concerns.
Manage Your Training Load
Shin splints are fundamentally an overuse injury. The bone and periosteum can handle a certain amount of stress, but when training volume or intensity increases faster than your tissue can adapt, microdamage accumulates faster than your body can repair it. The widely cited guideline of increasing weekly mileage by no more than 10 percent per week exists for this reason, though even that can be too aggressive for some runners, especially beginners or those returning from a break.
If you’re currently dealing with shin pain, reduce your running volume to a level where you can run without pain. That might mean cutting mileage in half, shortening individual runs, or replacing some runs with cross-training like cycling or swimming. Once you can run pain-free, build back gradually. Alternating run days with rest or cross-training days gives the bone time to remodel and strengthen between sessions.
Strengthen Your Lower Legs
Weak muscles in the front of your lower leg force your shinbone to absorb more impact directly. Strengthening the muscles that pull your foot upward (dorsiflexion) and the calf muscles that support the tibia from behind builds a more resilient system. Three exercises target the right muscles:
- Resistance band dorsiflexion: Sit with your leg extended, loop a resistance band around the top of your foot, and pull your toes toward your shin against the band’s resistance. Do 3 sets of 10 repetitions.
- Seated toe raises: Sit with feet flat on the floor, keep your heels down, and lift your toes off the ground. 3 sets of 10. Once this feels easy, progress to standing.
- Standing toe raises: Stand with feet flat, rock back onto your heels, and lift your toes off the floor. Hold for 5 seconds. 3 sets of 10.
Calf raises (both straight-leg and bent-knee variations) are equally important because the soleus and the deep toe flexor muscles attach along the inner border of the tibia. These are the muscles whose pulling force irritates the periosteum. Stronger calf muscles absorb more shock before that force transfers to bone. Aim for 3 sets of 15 calf raises daily, progressing to single-leg versions as you get stronger.
Check Your Foot Mechanics
How much your arch collapses inward when you step, a measurement called navicular drop, is one of the strongest predictors of shin splints. Runners whose arch drops more than 10 millimeters during weight-bearing are nearly seven times more likely to develop medial shin pain compared to those with less drop. You can get a rough sense of this by watching your arch in a mirror while standing on one leg: if it flattens noticeably, overpronation is likely contributing.
Supportive shoes with moderate stability features or over-the-counter arch support insoles can reduce the degree of pronation and ease the traction forces on your inner shin. Custom orthotics are an option for severe cases but aren’t necessary for most runners. If you’ve been running in minimalist shoes or worn-out trainers, switching to a shoe with more structure can make a noticeable difference within a few weeks.
Running Surface Matters, but Less Than You Think
Running on concrete does produce slightly higher tibial acceleration than running on grass. But the difference is smaller than most runners expect, with research showing only a small effect size between surfaces. Switching from sidewalks to a track or grass field can help at the margins, especially during a flare-up, but surface changes alone won’t solve the problem if your cadence, volume, or strength are the real issues. Think of softer surfaces as one tool, not the fix.
How to Tell If It’s Something Worse
Shin splints and tibial stress fractures exist on a spectrum, and catching a stress fracture early matters. With shin splints, the pain tends to spread across a broad area along the inside or outside of the shin, and it often improves as you warm up during a run. A stress fracture produces pain in one specific spot that you can pinpoint with a finger. That pain is reproducible, meaning it shows up every time you load the bone, and it doesn’t get better with continued exercise. It may also hurt at rest.
If your pain is localized to one spot, persists during rest, or doesn’t improve after two to three weeks of reduced activity and the strategies above, imaging can rule out a fracture.
Returning to Full Training
Before ramping your mileage back up, you should be able to meet a few benchmarks. Walking should be completely pain-free. Pressing along the inner border of your shin should produce no tenderness. You should be able to hop on the affected leg repeatedly without discomfort. These simple tests confirm that the bone and periosteum have healed enough to handle progressive loading again.
When you restart, begin with short, easy runs on alternating days. A common return protocol starts at 50 percent of your pre-injury volume, increasing by about 10 percent per week as long as you remain pain-free. Continue the lower leg strengthening exercises throughout this period and beyond. The runners who stop doing them once they feel better are the ones who end up with shin splints again three months later.
