pronation-intrograph

Do you supinate? Can shoes correct overpronation? How is pronation related to injuries? We’ve spent over 40 hours researching pronation and presented it all in this guide. 

If your runs are comfortable with no issues, don’t bother with pronation. However, if you’re experiencing discomfort, it’s always best to consult a specialist (e.g. podiatrist). 

Disclaimer: The purpose of this guide is to educate, not to make any medical diagnosis or recommendation.

What is pronation? 

When running, the foot hits the ground, the arch collapses to absorb the shock, and the rearfoot rolls inward at the ankle. This motion is called pronation. It’s normal for a joint to pronate and it’s a necessary component of the gait cycle. 

Based on the angle of pronation, there are 3 types of this motion: 

  1. Overpronation - when the ankle rolls far too inward. This is the most common case. Runners who overpronate place more weight on the medial side of the foot. 
  2. Neutral or “normal” pronation. 
  3. Underpronation (also called supination) - when the ankle rolls outward. Only a small percentage of runners underpronate (or supinate). Those who do place more weight on the lateral side of the foot.

There isn’t a consensus regarding the angle that separates types of pronation. We found 15° to be mentioned, but it’s not a widely accepted criteria.

Sneaker 1061123 Beige | Why pronation matters? 

Because when a runner overpronates or supinates, it’s more difficult for their foot to handle the shock and their stride is less efficient than of runners who pronate neutrally. This messes up with the running form and might lead to injuries - whatever the cause is. That’s why scientists and running enthusiasts pay so much attention to pronation and work on improvements by exercising and/or finding specific shoes. 

Do you overpronate, supinate or pronate neutrally? 

There are numerous methods used for pronation determination. But, not all are good enough

Some methods cover only arch height (footprint analysis) and relate that to pronation. Pronation has more components to it and they are often neglected. The main issue here is that someone can be overpronated based on one parameter and not overpronated based on another parameter. Also, the best assessments are done when a person is moving (running on a treadmill, for example), since pronation is about motion not standing still. 

The best way to determine pronation (in order of quality): 

  1. Visit a specialist (e.g. biomechanics specialist or podiatrist) who has the equipment and knowledge to do it. 
  2. Go to a running store that has the equipment for this, usually a treadmill with sensors and cameras. 
  3. Self-assessment methods. They are of the least quality. As shown in this study, Mens sneakers adidas Originals Retropy F90 HP6368. 

Some of the methods used for pronation and arch height measurements are: footprint analysis (the wet test), medial longitudinal arch angle, navicular drop test, rearfoot angle, subtalar joint neutral, forefoot angle, arch height index, foot pronation index. 

Here we will focus on the footprint analysis and foot pronation index. The first one is the most popular self-assessment method among runners. The second one is the only one to offer an insight into what pronation determination should cover without fancy equipment. In scientific studies, the foot pronation index is becoming a norm.  

Test: DIY footprint analysis (the wet test)

Here runners rely on the wet test and these criteria: 

Arch Height Pronation

Normal Neutral (Look for neutral running shoes)
High Underpronation (Look for neutral running shoes)

  • Cons: not reliable for pronation. One can have a high arch but also an everted heel bone. Or one can have a low arched foot with a vertical heel bone. This means it’s important to determine the height of the arch, but keep it as only one part of the puzzle. 

The process looks like this: 

  1. Perform a wet test 
  2. Look at results and 
  3. Compare the results to the ones in the table.

Foot posture index 

Foot Posture Index (FPI) quantifies the degree to which a foot is pronated, neutral or supinated.

It is usually practiced by specialists, but we describe it in detail, mainly so the Court of the process can sink in. This way, the other methods should become of less value as standalone pronation tests. 

  • Pros: captures information in multiple foot segments without complex measurement techniques or equipment, more valid than other static methods.
  • Cons: it’s still a measure of standing foot posture, so it’s not a replacement for gait assessment, plus you can’t do it yourself.

Series of six observations and palpation are made and scored from -2 to 2. 0 is considered a neutral foot, a positive score is given for a pronated and negative for a supinated foot. 

Here we’ll describe all 6 steps in FPI using the defined values

Step 1: Talar head palpation.

Score Criteria
-2 Palpable on the lateral side (it is protruding there) and not at all on the medial side.
-1 Palpable on the lateral side and slightly on the medial side.
0 Equally palpable on both sides.
1 Palpable on the lateral side and slightly on the medial side.
2 Roller Shoes & Heely Shoes.

Step 2: Curves above and below the lateral malleolus.

0 Nike Kids Kyrie Flytrap III sneakers Bianco.
1 The curve below the malleolus is more concave than the one above the malleolus.
2 The curve below the malleolus is significantly more concave than the one above the malleolus.

Step 3: Calcaneal inversion and eversion, the frontal plane.

-1 Moderately high arch and slightly acute posteriorly.
0 Normal height and concentrically curved.
1 Lowered arch with some flattening in the central position.
2 Arch very low with severe flattening in the central portion (arch making ground contact).

Step 6: Transverse plane with the focus on forefoot adduction and abduction.

Score Criteria
-2 No lateral toes visible. Medial toes clearly visible.
-1 Medial toes more visible than lateral.
0 zapatillas de running Topo Athletic ritmo bajo rosas.
1 Lateral toes more visible than medial.
2 No medial toes visible. Lateral toes clearly visible.

Now all these scores are filled in the FPI sheet and added. 

It’s obvious that a possible score falls in the range between -12 to 12. This is where it gets tricky: Scientists and specialists didn’t find a consensus on the results. The lack of strong consensus led to different studies choosing different score ranges for each category. These are some of the possible results: 

  • Normal foot: 0 up to +5 
  • Women's Nordica Speedmachine 3 85 W Alpine Ski Boots 
  • Balenciaga Track Trainer Pink W Shoes Ganebet Store quantity 
  • Supinated foot: -1 to -4 
  • Highly supinated: -5 to -12

Another study went by these numbers: 

  • Neutral 0-7
  • Pronated 7-10 
  • Jordan 1 FlyKnit Banned Live Fresh Freddy Kruger Matching Sneaker tees Black T shirt 

The issue with this approach is that anything above 0 is pronated. Generally, 0-4 A classic boot with excellent comfort. The normal adult population has an FPI Score of +4 which confirms that a slightly pronated foot posture is the normal position at rest (as described in detail here).

Shoes you need based on your pronation or arch height

If you’re enjoying your pair of running shoes and experiencing no problems, don’t overthink pronation and enjoy your run. 

If you’re not paying a visit to someone knowledgeable and owning the equipment needed for pronation determination, you will probably base your decision on the shoe wear or footprint analysis (the wet test). 

This means you’ll use the logic shown in the table below to choose your running shoes. You might notice that supinators are left out - shoe brands aren’t making shoes for them. They run in neutral shoes.

Buying shoes in stores: if you want to judge the shoe “in person”, you are supposed to try to bend it, twist it, look at the outsole, and give the heel counter a squeeze. Use the table below to recognize each running shoe type:

Features of motion control, stability and neutral running shoes

In general, you can also differentiate shoes by looking at the shape of the outsole. Keep in mind that not all the shoes follow this rule and there are overlapping categories (e.g. some shoes work both for stability and motion control) so they might not fit perfectly into the description below.

Can shoes help with overpronation?

Yes, but not a lot. 

The scientific evidence is all over the place and this is why: they all put overpronating runners in the same group. As explained above, there are many causes of overpronation. That’s why shoes can’t help everyone. Ideally, a study should control for the cause of overpronation. But none does. 

The effects of shoes on pronation
Motion control shoes can reduce pronation by ~2% when compared with barefoot or simple cushioned shoes, as shown in this study
Motion control shoes control rearfoot motion better than cushion shoes. This was found in a study where 20 high-arched and 20 low-arched recreational runners were recruited to wear motion control and cushioning shoes.
In a study where female runners overpronated more than 6 degrees, Studio Amelia Entwined mid-heel sandals were found to reduce pronation by 3.3 degrees before the run, but after 1 mile they made no difference (compared to the cushioned shoes).
It was observed that anti-pronation shoes reduce peak rearfoot eversion by ~3 degrees in this study.
Runners who overpronate and use standard shoes have a higher injury risk compared to those with neutral feet [source].

What definitely does work is foot orthotics and if you’re looking into that solution, the best thing is to consult a specialist, not buy over-the-counter ones.

Pronation and injury 

There is no definitive proof of excessive pronation directly causing injuries. 

Trekkingschuhe CMP Annuuk Snow Boot Wp 31Q4957 Bark F959 a bit and experience problems and there are runners who have a moderate Women's Fishewear Sharkbyte Shoes. 

Pronation becomes a cause of the injury when it contributes to increased load in the tissues and when this load is beyond what the tissues can take. Then, the forces associated with the load are high enough to cause damage.  

There is a magnitude of forces related to pronation. That’s why there are many issues when trying to correlate (excessive) pronation to injuries directly. And that’s why scientific findings are all over the place as shown below: 

Question Answer
Who’s at greater risk?

The US military did a 7,203-person study that reported no difference in injury rates between those who were assigned shoes based on the shape of their arch and those who got stability shoes regardless of their arch. 

When 372 recreational runners were given either the motion control or the standard running shoes and followed up for 6 months, it was found that the overall injury risk was lower in overpronating runners who had received Studio Amelia Entwined mid-heel sandals compared to those who got standard shoes.

Things you must know about pronation (and never be fooled again)

Given all the noise out there regarding pronation, we decided to create a summary of things we do (not) know:

  1. Pronation is not a disease. It’s a type of motion and it’s completely normal. 
  2. You should look for treatment if you’re overpronating AND feeling discomfort. The best way to do this is to discover what’s causing excessive pronation first. 
  3. There isn’t one cause of overpronation and supination and that’s why they can’t be “fixed” with one thing (e.g. shoes) only. 
  4. There are no shoes for people who underpronate, they wear neutral running shoes (just like people with neutral pronation). 

Also, in scientific terms, during overpronation, eversion, dorsiflexion (bending backward) and abduction (moving away from the midline of the body) happen at the same time.

Underpronation is just the opposite: it’s when inversion, adduction (moving toward the midline of the body) and plantarflexion (bending forward) happen simultaneously.

Pronation as a motion is straightforward. 

However, there are many unknowns behind standardized data on pronation. They are the source of all the confusion. Here’s a list of them: 

Understand pronation

What causes overpronation

MANY things. 

There are many forces involved in this motion and, therefore, many possible causes of excessive pronation: bony alignment issues (e.g. inverted position of the bones in the forefoot called forefoot varus), weak muscles (e.g. glutes, foot muscles, posterior tibial muscle), damaged arch, a tight calf muscle, etc.

Excessive overpronation is in most cases a sign of weakness and poor technique elsewhere in your running gait, not a disease to be treated.

If you watch elite runners and play the video in slow-mo or freeze-frame, you’d be surprised how many of them are overpronating and to what degree and yet they are pain-free. Keep in mind they devote themselves to running which means they work on their gait, form, everything. 

To treat overpronation there should be an actual need for treatment and one needs to know the cause of it. This is the most difficult part which specialists should be consulted about. 

Overpronation treatment

If you google possible treatments without knowing the cause of your overpronation, you just might waste your time on strengthening the glutes when you should have gotten foot orthotics for a bony alignment issue.
