If you’ve been running for a while, chances are you’ve either dealt with tight shins or shin splints yourself or heard a running buddy complain about them.
Tight shins are extremely common, especially if you’re new to running or returning after a period of time off. But even experienced runners aren’t immune — it can show up after a tough speed session, a long downhill run, or even switching to new shoes.
The good news? You can fix this. Once you figure out what’s behind the tightness, it’s usually pretty manageable.
In this guide, we’ll go through eight of the most common reasons runners get tight shins, and more importantly, how to relieve the discomfort and keep it from coming back, so you can stay consistent with your training.

The Main Causes of Shin Pain in Runners: Muscular, Bony, Neural, and Vascular
Many runners complain of painful or tight shins when running. Although we often refer to shin pain from running as “shin splints,” this is less of an actual diagnosis or specific condition and more of an umbrella term that may describe several different causes.1Bates, P. (1985). Shin splints–a literature review. British Journal of Sports Medicine, 19(3), 132–137. https://doi.org/10.1136/bjsm.19.3.132
Shin pain in runners can have four potential primary origins: muscular, bony, neural, and vascular.
#1: Muscular Causes of Shin Pain
One of the most common reasons for tight shins while running is muscle overuse or tightness in the medial compartment of the lower leg, particularly along the inner side of the shin.
This discomfort often involves the tibialis anterior or tibialis posterior muscles, or irritation of the periosteum, the connective tissue that anchors these muscles to the tibia (shin bone).
When these muscles are overworked or strained, whether from ramping up mileage too quickly, poor running mechanics, or a lack of mobility, they can become inflamed or irritated. This not only causes tightness but can also lead to pain along the shin, especially during or after a run.

#2: Bony Causes of Shin Pain
Runners can develop stress injuries, such as medial tibial stress syndrome, stress reactions, and stress fractures, in either one of the two long bones in the shin, the larger tibia, which is on the inside, or the smaller fibula, which is on the outside of the leg.2McClure, C. J., & Oh, R. (2019, April 4). Medial Tibial Stress Syndrome. Nih.gov; StatPearls Publishing. https://www.ncbi.nlm.nih.gov/books/NBK538479/
Tibial stress fractures are more common in runners than fibular ones because the tibia absorbs the majority of the weight upon loading.
Stress injuries result from overuse when the rate of stress applied to them exceeds the rate at which they can adapt and remodel.
#3: Nerve and Vascular Causes of Shin Pain
Sometimes, tight or painful shins aren’t just about muscles. Nerve or vascular issues can also play a role. One of the more serious conditions to be aware of is compartment syndrome, where pressure builds up within the tight muscle compartments of the lower leg, particularly around the shin.
This increased pressure can compress nerves and blood vessels, leading to pain, tightness, numbness, or even weakness during or after running.
In severe or chronic cases, surgical intervention may be necessary to relieve the pressure and restore proper circulation.

8 Sneaky Culprits Behind Shin Tightness in Runners and How to Fix Each One
We’ve discussed several potential root causes or diagnoses underlying shin pain from running. But – how do these occur? What causes shin injuries in the first place?
#1: Doing Too Much Too Soon
Shin splints are particularly common among beginner runners who ramp up their mileage too quickly. The muscles in the lower leg are small and relatively weak, but running requires them to work hard with every step to control the motion of the foot and ankle.
Muscles like the tibialis anterior and tibialis posterior suffer microtears when you run, but this damage can fail to heal between runs if you run too much too soon without adequate recovery time. The muscles and periosteum can become inflamed, leading to tight shins.
Even experienced runners can suffer from shin splints if they increase their volume significantly or make other sudden changes to their training routine. When the rate of tissue damage exceeds the rate of recovery and repair, running injuries often ensue.

#2: Running In Old Shoes
Worn out or unsupportive shoes can lack the cushioning and support needed to keep your body healthy.
Shoes that do not properly control pronation of the foot will make the tibialis posterior need to work extra hard to control the foot, ankle, and arch. This can strain the muscle and cause inflammation and injury.
That’s why it’s important to regularly assess the condition of your running shoes and replace them when needed, typically every 300–500 miles, depending on your running surface, gait, and shoe type.
If you notice increased shin tightness, new aches and pains, or visible wear on the outsole or midsole compression, it might be time for a new pair. Investing in the right shoes can go a long way in reducing muscle strain, improving running mechanics, and keeping shin pain at bay.
#3: Tight Calves
When your calves are tight, it can cause the muscles in the front of the shin to be overstretched. Chronic overstretching or eccentric contractions of the shin muscles can lead to micro tears and inflammation.
Make sure to warm up before and cool down after your exercise routine in order to keep yourself as pain-free as possible and minimize the risk of shin splints.
#4: Heel Striking
Heel striking, which can be due to overstriding, transmits more impact stress up the shin than a more forward-propulsive midfoot striking pattern.
Heel striking can also occur if you wear running shoes with a large heel drop, which can lead to the heel hitting the ground first.
To reduce stress on your shins, it’s worth taking a closer look at your running form and footwear. Shortening your stride and working on a more efficient midfoot strike can help lower the impact forces that travel up your legs with each step.
Additionally, if you’re wearing shoes with a high heel-to-toe drop, consider gradually transitioning to a pair with a lower drop to encourage a more natural footstrike, but do so slowly to avoid other issues.
Small adjustments in form and shoe choice can make a big difference in preventing shin pain over the long run.

#5: Hard Running Surfaces
Running on hard surfaces like concrete and asphalt can cause shin pain. These surfaces have very little give and transfer more impact shock up the leg than softer running surfaces like grass, cinder, and trails.3Tessutti, V., Ribeiro, A. P., Trombini-Souza, F., & Sacco, I. C. N. (2012). Attenuation of foot pressure during running on four different surfaces: asphalt, concrete, rubber, and natural grass. Journal of Sports Sciences, 30(14), 1545–1550. https://doi.org/10.1080/02640414.2012.713975
Mixing up the surfaces and terrain you run on can help prevent overuse injuries, such as shin splints, because the variety alters the muscular workload and application of stress on the shin bones and connective issues.
#6: Running On Cambered Roads
Cambered roads are sloped from side to side to allow water drainage. However, this slope is usually most significant in the shoulder of the road where runners are running.
Running on a cambered road tilts the pelvis and lifts one hip higher than the other, which can cause excessive stress on one of the legs. Some runners develop shin splints or stress injuries from chronic training on uneven roads.
Try to avoid excessive running on cambered roads.

#7: Overpronation
One of the most common biomechanical causes of shin splints in runners is overpronation, which refers to excessive rolling inward of the feet.
When the foot overpronates upon landing, the arch collapses and the ankles roll in, placing torsional stress on the shin. This overstresses and over-stretches the muscles in the shin that control pronation, such as the tibialis posterior.
This can be a bit of a chicken-or-egg scenario. If your feet are flat and overpronate, it can cause excessive strain on the tibialis posterior, but likewise, if your tibialis posterior is weak, it can cause overpronation of the foot because the muscle lacks the strength needed to control pronation.
Overpronation is more common in those with flat feet or weak arches.
#8: Weak Hip Abductors
The muscles on the lateral portion of the glutes, namely the gluteus medius, play a key role in controlling the alignment of the entire lower limb. Weakness in these muscles can cause the legs to roll inward, leading to a pattern of inner stress down the kinetic chain through the knees, shins, and feet.
Weak hip abductors can cause shin splints by causing the knees to collapse inward and allowing an overpronation and an excessive demand on the muscles in the lower leg to control this inward rotation. Overworking the shin muscles can cause muscular strain and periosteum damage associated with shin splints.
Strengthening your hip abductors, especially the gluteus medius, should be a priority if you’re dealing with recurring shin pain.
Incorporating targeted exercises like clamshells, lateral band walks, and single-leg glute bridges into your routine can improve hip stability and help keep your knees and ankles properly aligned.
Better alignment means less inward collapse, less overpronation, and ultimately, less strain on the shin muscles. A strong, stable pelvis sets the foundation for healthy, efficient running mechanics from the top down.

How to Treat and Prevent Tight Shins With 10 Coach-Backed Tips That Actually Work
Treating shin pain or tight shins when running comes down to resolving whatever issue is causing the problem. In most cases, the general principles of RICE (rest, ice, compression, and elevation) are helpful as this conservative treatment protocol can help reduce inflammation.
The following are additional tips to treat and prevent tight shins and common causes of shin splints in runners:
- Change your running shoes every 300-500 miles. Make sure your shoes provide adequate support to your arch and prevent overpronation. Studies show that rotating your running shoes can also keep them fresh and may help prevent sports injuries.4Malisoux, L., Ramesh, J., Mann, R., Seil, R., Urhausen, A., & Theisen, D. (2013). Can parallel use of different running shoes decrease running-related injury risk? Scandinavian Journal of Medicine & Science in Sports, 25(1), 110–115. https://doi.org/10.1111/sms.12154
- Run on softer surfaces like grass, trails, or cushioned treadmills.
- Progress mileage and intensity gradually. Heed the 10% rule, meaning you should only increase your mileage by a maximum of 10% from one week to the next. For example, if you are currently running 25 miles a week, run no more than 27.5 miles next week.
- Stretch your calves several times per day.
- Soft tissue work like dry needling and myofascial release such as foam rolling can aid recovery, releasing trigger points and helping with tight calves.
- Strengthen your hip abductors and lower leg muscles. Heel raises, toe raises, single-leg balance, and foot doming exercises can strengthen the lower leg musculature.
- Take rest days, especially when you are coming back from time off or just starting.
- Avoid cambered roads, if possible.
- Cross-train with low-impact activities like cycling, elliptical, rowing, deep water running, and swimming while your shins heal.
- Work on your running form. Experiment with shortening your stride and increasing your cadence to reduce heel striking.

Should I Stop Running If My Shins Hurt?
While some aches and tightness in your shins after running aren’t cause for concern, if you’re experiencing significant pain, make sure to take a break from running or other high-impact activities and try lower-impact activities.
Again, follow the RICE principle of Rest, Ice, Compression, and Elevation to speed up recovery.
When Should I See My Healthcare Provider?
If the pain continues after you’ve rested your legs for a while and followed the above steps to treat shin splints, then see your healthcare provider or a physical therapist so they can create a specific plan for you.
