How to Read Your Running Shoe Wear Pattern: Learn About Your Stride, Best Shoe Type, & More

Your shoes can tell you a lot…including whether you are landing harshly, and which type of shoe might be best for you.

Most people don’t know it, but the wear pattern on a well-used pair of running shoes can tell a pretty good story.   That story may include the fact that you are over-striding and landing with more impact than you need to.  It may also tell you that you should work on strengthening your feet, or that you have a leg length discrepancy.   Often, runners go get a gait analysis at their local running store, not knowing that bringing a used pair of shoes can likely tell the staff a whole lot more about what shoes will be best for you than watching or filming you run ever could.  In fact, gait analysis for shoe selection can be misleading.   About 50% of all running shoes sold are so-called “Stability” shoes.  However, only about 1 in 9 running shoe wear patterns show that a runner *might* need of the so-called stability.

The first step to reading the wear pattern on your shoes is to get a well-used pair of running shoes that has only been used for running.  If they have been used for too much walking, this will throw off the wear pattern and make it hard to truly get a good read on what’s going on with your run.

Now that you’ve got a suitable pair of shoes to read, it’s time to flip them over and look at the wear pattern on the rubber outsole.  In my opinion, the most important thing you should look at is the heel area of each shoe.  If your shoes show significant wear at the outside back corner, you are likely over-striding and landing with a lot more impact.  A study by Harvard scientists found that over-striding, or excessive heel-striking produced three to five times more impact than runners who landed closer to underneath their bodies and didn’t land with a harsh heel-strike.  This type of landing also causes excess torque in the joints, which many scientists believe is actually even more of a cause of running injuries.

If your shoes show this type of wear, I recommend a few simple tips such as not letting the elbows swing forward past the hips and taking quicker steps.   Most runners have never had a running lesson, so finding a coach or running store nearby that teaches a class could be very beneficial.  For more on improving your form and optimizing your landing, check out the tips here.

Nearly all runners land on the outside part of their feet. Contrary to popular belief, landing on the

outside does NOT mean you are over-pronating.  It just means that you are normal.  Shoes are wider than human heels, and hips are wider than where your shoes hit the ground.  These two things make it so virtually every runner lands on the outside of their shoes.

Now that we know that landing on the outside is normal, the next thing to look at is which part of the forefoot of the shoe has the most wear.  Your foot absorbs impact by rolling inward and then pushing off your strongest toe, which is your big toe.  So, an ideal wear pattern will show the most wear on the forefo

ot in the middle to slightly inside part of the shoe. The running shoe world calls this “neutral.”  If this is you, avoid “stability” shoes and shoes with any kind of dark material under the arch or shoes with any extra arch support or “control” features.

If wear is more towards the outside, you aren’t pronating or absorbing shock very well, and you are a “supinator”, which is very rare…so much so that major running shoe companies don’t make supination specific shoes.

Pronated

If your wear is on the inside part of the forefoot, then you are likely an “over-pronator” meaning that your feet collapse more than usal, causing the leg to do the same and likely causing excess joint torque.  For some, this is a bone deformity, collapsed arch, or genetic inheritance.  For others, their feet are simply weak from a lifetime of wearing so-called “supportive” shoes and/or orthotics that move the foot out of its natural position and weaken the foot muscles.  Most people that over-pronate will benefit from a foot strengthening regimen that could include standing on one foot, pulling a towel in with the toes, and/or running or walking short distances barefoot on soft surfaces.  A device called “Correct Toes” can also be a great benefit for strengthening the foot and helping to re-align it to its natural position.

If your wear pattern shows that you are an over-pronator, you may be among the 1 in 9 people who may benefit from wearing a stability shoe until your feet re-align and get stronger.  As long as your wear pattern continues to show wear on the inside of the forefoot, it may be best to stick with a stability shoe.  However, it is important to note that outside of a weak link to shin splints, excess pronation has never been significantly tied to running injuries.  Additionally, traditional stability shoes with dual density or medial (arch) posting have also never been shown to actually reduce pronation, but rather only make it appear so.  Only varus wedges (a wedge that is higher on the inside of the foot than the outside) have been shown to truly reduce excess pronation. The question is whether we should be even be trying to reduce excessive pronation.

Also keep in mind that 83% of runners are less injured in a neutral shoe that doesn’t mess with what the foot and body naturally wants to do. About 1 in 6 runners is less likely to be injured while wearing a stability shoe.  However, only about half of those runners have excessive pronation—the other half have neutral biomechanics. One more thing to look for is irregularities between the left and right shoe.  This can give you clues in to any imbalances you might have or injuries that occur due to this or favoring one leg over another.

One way to partially or even completely nullify unwanted stride patterns on a shoe is to run on uneven ground, such as trails, grass, or even cobblestones. If you run off road enough, the irregular surface can improve your technique and help correct any imbalances you might have.

Reading your shoe is one of the most effective ways to know what is going on with your body, and is in many ways more reliable than photos, video, or other ways of seeing the way you run.  Most importantly, know that according to studies done on running shoes and injuries, runners will be least injured in the shoe that they feel the most comfortable, relaxed, and free in *while running*—regardless of category. So go in to your local running store and try on a half dozen pairs of different types of shoes and buy the one that feels the most comfortable and like it’s not there—even if you have a neutral wear pattern and that shoe happens to be a stability shoe!
