How To Avoid Getting Shin Splints While Running? Key Facts

Shin splints are one of the most common running injuries, and they are also one of the most preventable. The pain shows up along the front or inner edge of the lower leg, usually after a jump in training or a change in surface or shoes. The core prevention strategy is simple to state and harder to follow: increase your training load gradually, strengthen the muscles and bones that absorb impact, and treat early pain before it becomes a stress injury. Most runners who make these changes do not get shin splints again.

What Are Shin Splints, Exactly?

The medical term is medial tibial stress syndrome, often shortened to MTSS. It describes pain along the inner border of the shinbone, the tibia, where muscles and connective tissue attach to the bone.

Shin splints sit in a family of overuse injuries. They are not a single torn structure the way a pulled muscle is. Instead, repeated loading causes irritation where the tibia meets the surrounding tissue. That is why the pain tends to build over days or weeks rather than appearing after one run.

It matters to separate shin splints from a tibial stress fracture. Both cause shin pain, but a stress fracture is a small crack in the bone and needs different care. A stress fracture usually causes pain in a more pinpoint spot. The pain may continue during normal walking, and it may hurt at night. Shin splints tend to cause pain spread over a broader area of the inner shin, and the discomfort often eases once you stop running.

If you cannot tell the two apart, that is a reason to see a clinician, not a reason to keep running. A doctor can examine you and, when needed, order imaging. Getting this distinction right early can prevent a long recovery.

Why Do Runners Get Shin Splints?

Shin splints come from doing more than your legs are ready for. The tissue gets loaded faster than it can adapt, and the result is pain.

Several factors tend to show up together in runners who develop it:

• A sudden increase in weekly mileage or pace
• Running more hills or more speed work than usual
• Switching to a hard surface, like concrete, after training on softer ground
• Worn-out or inappropriate shoes
• Weak calf and foot muscles that cannot absorb impact well
• A rapid return to running after time off

Some research suggests that people with certain foot shapes, or with flatter feet, may be at higher risk. The evidence on footwear and foot type is mixed, and no single factor explains every case. What holds up best is the training load itself.

One thing worth understanding: shin splints are not caused by a lack of willpower or by running “wrong.” They are a load problem. The fix is usually about managing load, not about running harder to push through.

How To Avoid Getting Shin Splints While Running

The most reliable way to prevent shin splints is to follow the rule that training increases should be small and steady. A commonly cited guideline is to raise weekly mileage by no more than about 10 percent per week. That figure is a general rule of thumb rather than a strict law, and some runners tolerate faster increases while others need slower ones. The principle behind it is what matters: give tissue time to adapt.

A few habits support that principle:

• Build gradually. Add mileage or intensity in small steps, and hold each new level for a week or two before adding more.
• Change one thing at a time. Do not increase mileage, add hills, and switch shoes all in the same week.
• Follow hard days with easy days. Impact tissue needs recovery time between demanding runs.
• Replace worn shoes. Cushioning breaks down over time. There is no universal mileage number that fits every runner, so replace shoes when they feel flat or compressed.
• Warm up. Start with easy jogging or walking before faster work.

Strength training deserves special attention. The calf muscles and the muscles around the foot help absorb the force of each foot strike. When they are weak, more of that force reaches the shinbone. Calf raises, both straight-leg and bent-knee versions, are the most direct exercises for this. Some evidence supports strengthening as a way to reduce shin splint risk, though the research is not as strong as it is for load management.

Does Footwear or Orthotics Help?

Shoes and inserts get a lot of attention, but the evidence that any specific shoe prevents shin splints is limited. No single shoe design has been shown to prevent the injury across all runners.

What is reasonable: wear shoes that fit well, are appropriate for your running, and are not worn out. If you have foot pain or a specific structural issue, a clinician or a physical therapist can advise on whether an orthotic might help. Some clinicians recommend orthotics for certain foot types, but this is not a universal fix and should not replace training adjustments.

Be cautious of any product marketed as a guaranteed cure. No shoe or insert has been shown to prevent shin splints on its own.

What Should You Do If Pain Starts?

Catching shin splints early is the difference between a few easy days and several weeks off. When you first notice shin pain, reduce your running load before the pain gets worse.

General steps that are widely used:

• Cut back on mileage or intensity for a short period
• Switch to low-impact activity, such as cycling or swimming, to keep fitness while the shin rests
• Apply ice to the painful area for short periods
• Return to running gradually once pain has settled

If the pain does not improve with rest, gets worse, or becomes pinpoint and sharp, see a clinician. Persistent shin pain can signal a stress fracture, which needs proper evaluation and a longer recovery. Do not try to run through pain that is getting worse.

One clarification worth making: rest alone often is not enough. If you return to the same training that caused the problem, it tends to come back. The lasting fix combines recovery with a gradual rebuild and strengthening.

Who Is Most at Risk?

Shin splints are common in runners, dancers, and military recruits, all groups that do a lot of repetitive impact. New runners are especially vulnerable because their tissue has not yet adapted to running loads.

People returning after a long break face similar risk. Fitness comes back faster than the bones and connective tissue can adapt, so the urge to jump back to old mileage can cause trouble.

Being at higher risk does not mean injury is inevitable. It means the gradual approach matters more, not less.

Can Shin Splints Be Prevented for Good?

For many runners, yes. When the cause is a training load that outran the body’s ability to adapt, fixing the load and building strength can keep the problem from returning.

That said, some people are more prone to overuse injuries, and no approach guarantees zero risk. The goal is to lower the odds and to catch problems early when they do appear.

The habits that prevent shin splints are the same ones that support healthy running in general: steady progress, adequate recovery, and attention to early warning signs. None of them are complicated. Following them consistently is the hard part.
