The Ultimate Guide to Shin Splints for Runners

The scientific symptoms, causes, and research backed treatment options to help you get rid of and avoid shin splints forever.Medial tibial stress syndrome, more commonly referred to as “shin splints,” is probably the most universally-known running injury.

Shin splints classically present as an aching pain on the inside of the shin, near the border of the tibia and the calf muscles.  The area will often be sore when poked or prodded, and will initially hurt at the end of a run. As the injury progresses, the pain will sometimes move to a more sharp, burning sensation, and may hurt during your entire run, or even when just walking around.

Shin injuries can be diffuse, spreading out over many inches along the length of the tibia, or be localized to a small area less than two inches long.  Serious cases of medial tibial stress syndrome, especially when localized to a small area, need to be distinguished from a tibial stress fracture, which can be accomplished with an MRI or a bone scan ordered by an orthopedist or podiatrist.

While not the most common running injury, medial tibial stress syndrome, or MTSS, still accounts for about 5-6% of all total injuries.1, 2

Unlike many injuries, which seem to strike at runners of all fitness levels, shin splints are much more common among less experienced athletes.  In a typical three-month high school cross country season, for example, between 12 and 15% of the runners on a typical team will suffer from shin splints.3, 4

Woman are 2-3 times more likely to develop shin problems than men.5  Additionally, among studies of military recruits, soldiers and sailors in poor physical condition (who likely have little history of athletic activity) are much more likely to suffer from shin splints.6

In contrast, very few experienced runners have to deal with shin pain on a regular basis.  Understanding the mechanism of injury can help explain why.

Causes of shin splints and what makes the injury worse

For a long time, shin splints were postulated to be a soft tissue injury.  Many of the muscles of the lower leg, including the calves and the smaller muscles above the ankle, insert along the tibia.  It was proposed that tightness or weakness of these muscles caused them to tug at their insertion point, irritating the periosteum, a thin, skin-like structure that envelopes the tibia itself. This distinguished medial tibial stress syndrome from tibial stress fractures and stress reactions, which are indisputably true bone injuries.

However, more precise anatomic studies have demonstrated that the muscular insertions blamed for causing shin pain do not correspond to the location of the injury;7 instead, advanced medical imaging studies have illustrated that all overuse injuries to the tibia, from mild cases of “shin splints” to true stress fractures, exist on a spectrum of bony injuries.

The most telling fact is localized bone density: in CT scans of the tibias of runners with shin pain, pockets of low bone density appear at the location of pain.  After these runners have recovered, these pockets of low density have disappeared.8  Additionally, runners with tibial stress fractures often have larger areas of lowered bone density around the fracture.

With this new information, scientists now hypothesize that the root cause of shin splints is repeated stress to the bone during running, caused not by straight-on impact, but a slight bending of the bone when it is loaded.

Much like a beam on a bridge or in a skyscraper bows slightly when it’s supporting a lot of weight, your tibia bends backwards slightly on impact with the ground, putting compressive forces on the medial side of the bone.

In healthy runners, the bone stress after a long, hard run is not a problem.  The body responds to the stress on the bone by remodeling the tibia to be stronger and thicker.  This is why shin problems are more common in less-experienced runners: their bone has not yet adapted to the stresses of a high-impact activity like running.

Unfortunately, this remodeling process takes several weeks to a few months to complete, and there is a period where the bone is actually more vulnerable to damage.

Just like remodeling your house entails tearing out some walls before adding new construction, your body has to tear out some of the old bone tissue before strengthening it.  As a result, having a small tibia or weak bones puts you at an increased risk for shin splints, since your weakened tibia is more vulnerable to injury when it is remodeling its bone structure.

Research backed treatment options for shin splints

The current theories for treating and preventing medial tibial stress syndrome revolve around reducing the relative amount of stress on the tibia.  Reducing impact and tibial loading, strengthening the supporting muscles, and strengthening the bone itself should all lower your risk of developing shin splints and may also speed recovery.

Unlike some other running injuries, there are no solidly vetted treatment protocols.  Rather, what follows is an extension of work on the precipitating factors for shin splints.

  • Reducing impact loading should be a priority for anyone with shin problems.  Increasing your stride frequency by about 10% (bringing it close to 180 steps per minute or more) will markedly decrease the impact your tibia has to absorb each time your foot strikes the ground.9
  • Strengthening your calf and shin muscles might absorb some shock, reducing the strain on your tibia, but more importantly, will lead to a stronger tibia in response to the increased muscular strength and size.  It’s been demonstrated that female runners with a small calf circumference have a much higher risk of developing a tibial stress fracture,11 so it is no surprise that runners with shin splints have poor calf strength.12

While there is no set protocol as of yet for increasing calf strength, a program of standing calf raises to fatigue twice daily will go a long ways towards building your lower leg strength.  There is also a lower-leg-strengthening routine we’ve  developed, outlined below.  These can also be done once or twice daily, and ought to be done barefoot on grass if possible.

1. Heel walk x 15 each foot

2. Toe walk x 15 each foot

3. Feet out walk x 15 each foot

4. Feet in walk x 15 each foot

5. Ankle in walk x 10 each foot

6. Ankle out walk x 10 each foot

7. Eccentric calf straight leg x 25 each foot

8. Eccentric calf bent leg x 25 each foot

12. Shin exercises with thera band x 10 each foot

Other possible treatment options for shin splints

With respect to orthotics, a few studies have demonstrated some success in using custom shoe inserts to treat shin splints.13  This is a good sign, as many other injuries respond poorly to treatment with orthotics.  Custom inserts might shift the distribution of pressure on the bottom of the foot, which may be associated with shin pain.

Nevertheless, orthotics are not a panacea and shouldn’t be your only treatment method.  Many runners find good success with over-the-counter semi-rigid orthotics like the SuperFeet or PowerStep insoles, and these are much cheaper than custom orthotics, so give them a shot first.

Among more exotic treatments, extracorporeal shockwave therapy (ESWT) has emerged in recent years as a treatment possibility.  In ESWT, shockwaves are applied directly to the tibia to encourage new bone growth.  Only one study has tested ESWT, and it suffered from some design flaws, but it showed a significant reduction in recovery time.14  ESWT treatment may be expensive and difficult to find, and its experimental evidence is still not up to snuff.

Outline of Treatment for Shin Splints

Conservative treatments

These are methods that are fairly simple, inexpensive, and can be done on your own at home.

  • Work to reduce stress on the tibia by increasing your stride frequency by 10% or so to avoid overstriding and excessive impact.
  • Calf raises starting with one set of 20 repeats and building to three sets of 20 (or more), twice per day.
  • Our preventive foot drill routine. Once per day:
    • 1. Heel walk x 15 each foot
    • 2. Toe walk x 15 each foot
    • 3. Feet out walk x 15 each foot
    • 4. Feet in walk x 15 each foot
    • 5. Ankle in walk x 10 each foot
    • 6. Ankle out walk x 10 each foot
    • 7. Eccentric calf straight leg x 25 each foot
    • 8. Eccentric calf bent leg x 25 each foot
    • 12. Shin exercises with thera band x 10 each foot
  • Modify your training so you don’t put as much stress on your tibia.  Reducing mileage, intensity, and duration of your runs will all help.  Remember, it can take several weeks to a few months for the tibia to heal.

Aggressive treatments

These are treatments with more cost and less certainty about outcomes, but may prove useful in recalcitrant cases.

  • Custom shoe orthotics or over-the-counter semi-rigid orthotics (SuperFeet, PowerStep) may be able to modify how forces are transmitted up the tibia, though this is unproven.  Many runners find that orthotics greatly improve their shin pain, but possibly just as many find that they are no help.
  • Consider running in a thinner, firmer shoe on a harder surface.  While the actual benefit for people with shin pain is as-of-yet unproven, biomechanics research has linked soft surfaces and soft shoes with higher leg stiffness, which is itself connected to higher shocks going up the tibia on impact.
  • Also consider taking a calcium/vitamin D supplement with 200% of your RDV of both.  One study found that doing so reduces the risk of tibial stress fractures by 25%.  Since MTSS is on the same “injury spectrum” as a tibial stress fracture, it’s possible that supplementation can help prevent medial tibial stress syndrome too.15
  • If conservative treatments don’t help, you also should be evaluated by a doctor for a tibial stress fracture.  X-rays are very inaccurate for diagnosing stress fractures, so your doctor should use either an MRI or a bone scan.  MRIs are slightly more accurate and allow your doctor to get a better idea of the severity of the injury, so they are generally the preferable imaging technique.

Return to running

You will need to modify your training program to allow your body time to strengthen your shin bone.

Mild cases of shin splints may only require modifying your running form and doing some lower leg strength, but more serious cases will require at least a few weeks off.  Keep in mind that shin splints are the same type of injury as a stress fracture, so if you feel like your shin injury is getting worse, you should not continue to run on it.

While many coaches recommend that a “10% rule” for increasing mileage is best to avoid injury, the dynamics of the tibia’s healing mechanism suggest that perhaps a stress/adaptation cycle would be better.  So, instead of increasing mileage every single week by 10%, you might increase by 10% for three weeks, then take a “down week” to allow your tibia to recover (ex. 40mi-45-50-40-50…).

Good luck with your shin splints. Let us know in the comments section if you have any helpful remedies or if you have questions we can answer.

  1. My case of MTSS showed up following an extended layoff due to a sfx in my right foot. I would consider myself a pretty experienced runner and haven’t dealt with “shin splints” since high school back in the 1980s. When I began running again (a very conservative buildup) after a few weeks I noticed tenderness along the tibia in on the same side as my sfx. That was in May of this year and this is what I can tell you about it since…
    The tenderness is always there. It is most noticeable after running a faster pace. Too much speed for too long and it really barks at me. Icing helps as does stretching and rolling the calf on the same side. I already ran in OTC orthotics (Superfeet) but I cannot say if they help with this or not. The type of shoe I wear seems to make little difference. Low drop or medium drop, mild stability or neutral, cushioned or not it all comes down to my pace. If I stay away from the redline it is quite manageable. And since the sfx I have taken calcium supplements.
    I have done some strength work but likely not enough. I’ll give that a try and dedicate several weeks to the program you outline above. Hopefully that will help. Thanks for the useful information.


    • Hi James! I am going through the EXACT same thing…I had a stress fracture on the inside of my lower right leg (happened while coming back from an ankle sprain). It was July when I was announced healed, but I am still experiencing pain around the spot where my stress fracture was. I just got an MRI, and it came back clean. The dr says I’m just battling shin splints. It is heartbreaking because I am a sub 3-hr female, but yet, I don’t even feel healthy enough to do a workout. I worry that I’ll never be able to train and race again. I was curious if you had any updates or had any tips? Thanks so much!!

  2. A year ago I had to stop all sports and running due to shin splints. I couldn’t walk without pain especially in cold weather. A podiatrist told me I had fallen arches and i needed insoles else I would have shin splints for the rest of my life. I did nothing for a full month. Then started barefoot running. 100 meters a day at first, increasing each week by a little. I started landing on my mid foot and my cadence increased. Then I bought some vibram’s and can now run 10 miles in a city on concrete. Shin splints have never returned.

  3. I have no pain while running but a few hours after running my shin muscle throbs and i feel an occasional pulling. Could this be a MTSS or a stress fracture?

  4. Hi Tanya,

    Is it possible that this is delayed onset muscle soreness? I’d check into that.

    I don’t have any professional education in this but the soreness in the muscle is unlikley to be a result of MTSS. The pulling, however, could be. If you’re experiencing it along the inside (or outside) of the shin bone (typically more towards the ankle on the inside), it might be MTSS.

    I’ve had MTSS issues for years. Particularly after having multiple ankle injuries including a stress fracture. This article seems very useful for addressing shin splints (strengthening and increasing cadence are definitely two things that have been helping my very slow progess).

    Good luck!

  5. Hi,
    Back in 2000 I was in the army and suffered from shin splints. I saw a Dr and was told to sit out of PT for about a week. Fast forward to 2014 and when I run or walk for more than 29-30 mins I still suffer from it. Could this be an issue from 2000?
    Thank you

    • Hi Pualani, it is most likely that you have just redamaged the tissue. It is near impossible to determine an exact cause of your current pain, but it would be best to take our suggestions from this post, and help it calm down before you continue. Make sure you build up slowly also! Hope this helps!

  6. Hi, I have the same issue. My pain started over year ago when I was playing basketball in low shoes. At first my tibia was hurting alot, but now it hurts only after practice. Also, it’s not flat, its kinda bumpy in lower part of my tibia… it first started on my right leg, and now is on the left, too…

    • Thanks for sharing Phillip. Be careful with the pain, and monitor it as best you can. Hopefully the suggestions we had provided you with some assistance of how to strengthen the surrounding muscles.

  7. It seems that every time I start running again (I do intervals of one minute running, 1 minute power walking) after resting for my shin splints, they return after a week or so. After reading this I realized I was heel striking and reducing my gait as well as making sure to land on the middle of my foot has seemed to help me a good deal, so thank you!

    I am trying to find a description of some of the exercises you mentioned, but am coming up short. Could you describe the feet in/out walk and ankle in/out walk? And the shin exercises with theraband?

    • Hi Alexis, glad you found that reducing the length of your stride to prevent over striding helped. You may also enjoy our podcast discussing this http”//runnersconnect.net/rc43

      As for the exercises, this article has videos of many of our exercises that may be helpful for you, as these will help prevent future injuries http://runnersconnect.net/running-injury-prevention/shin-splint-exercises/. To have access to the rest of the exercises, your best bet is to sign up to our newsletter (at the top of the page), and we will send you emails tailored to your needs. Which will hopefully give you the information you need. Hope this helps!

  8. Hello, recently I been feeling pain in both my legs and everyone tells me its shin splints. I usually run for an hour- 40 minutes, 5 days a week. I stared exercising 6 months ago and since I got condition, I’ve been running/jogging as much as I can. Several times, I’ve stopped running because my legs are in pain. When I walk fast, they also hurt. For how long should I rest? Should I go see a doctor? Will my legs get better any time soon if I stop exercising for a while?

    • Hi Dinorah, sorry to hear that, but yes, your best bet would be to see a doctor to find out what is going on. This article should provide you some assistance with other steps you could take, you should try to stay away from pavement/cement and move towards grass surfaces. The pain will likely subside after some rest. Hope this helps!

  9. I think I have shin splits, but I’m not sure. The pain I get is on the outside of my shin, and oddly it hurts the most when I slow down to a walk after a bit of running.
    For example – today, 5 minute walking warm up, then 5 minute run at 6.2mph, slow back down to a 3.6mph walk, and the pain kicks in, and is a solid 6.5 on the pain scale. I slow down to a 3.1, and the pain fades quite a bit, but I can still notice it. Run again for another 5 minutes, and a couple tweaks of pain, slow back down to walk, and the shins ache at about a 3.5 on the pain scale. I only run/walk anywhere from 30 – 60 minutes at a time, trying to build my endurance.

    Other days they will hurt during the run and walk. I bought a foam roller, and have started using it daily, plus a resistance band to do lower leg stretches from my physiotherapist. It doesn’t really sound like true shin splints though. Maybe I’m just “different”.

    • Hi Dawn, that does sound like the symptoms of shin splints, a lot of injuries are most prevalent after running. You are definitely normal, and a lot of runners have this. If you follow the exercises and suggestions in this post, you should find some comfort. It does not sound like your shin pain is bad enough to require time off….yet, if you take care of them, you can continue to run/walk, but keep an eye on it. If it gets worse, then you may consider some rest.

  10. Personal experience resting was no help as it starts up again shortly after. Change shoes and try shop bought arch support if you have a low arch. Bare foot runs good and increase cadence if you have been running for a while most injuries are just a reminder of good running form head over heels etc. To get running again I have found do race walking for a week following week ease the walking into nice form jog stop when pain comes in and walk again to finish exercise. Increase till you forget you had an injury. Long compression socks also good when exercising and also in bed nothing like making the injured area sweat while resting.

    • Hi Paul, thanks for sharing your thoughts, some great tips there. For shin splints though, most people will need the rest for their shins to recover. You are right though, runner will need to make sure they make the changes so they do not happen again, and we are big fans of the walk run method. We have a grew podcast you may enjoy listening to if you want to check it out http://runnersconnect.net/rc43. Hope you enjoy, and thanks for your recommendations!

  11. Hello, I am a freshman at Westosha Central high school, and I love to run cross country and track. I, however, have shin splints very very often. I started getting them during 6th grade track and I have had them ever since, they are really on and off and are really painful. I have been wearing compression sleeves all day, I take ibuprofen, I ice, ALOT and do shin exercises and calf stretches. I even got custom fitted shoes and custom orthotics for my feet, they molded my feet. However, they just keep coming back. Sometimes it might be because I increase mileage to fast, but other than that, I just don’t know. I have had these stupid thing for over 4 years. I am pretty weak for a runner and I am really skinny with low BMI. I am 14 and I weigh 90 pounds, My 5k PR last September was 18:28. Is there anything you suggest? I get posterior shin splints on the upper part of my leg usually, and I also get anterior shin splints on my left shin, the side facing inwards…. Please help, thank you
