Do Running Shoes Actually Matter? What the Science Says About Foot Structure

So, you signed up for a race, now what? Today we’ll cover the basics of preparing your body to run and how to best avoid injuries by going over training programs, cross-training, and other important details. Last time, we discussed cross-training. Today, we’ll focus on equipment, specifically shoes, and whether finding the “right” shoe truly matters.

Foot Structure

First, let’s talk about foot structure. You’ve probably heard people describe feet as having “flat feet” or a low arch. In the physical therapy world, this foot structure is associated with the term pronated feet. The opposite, having a high arch, is known as supinated feet.

Before we go further, it helps to understand what pronation and supination actually are. Pronation is the natural inward roll of the foot as it strikes the ground, and supination is the outward roll. Both are normal parts of how your foot absorbs impact and propels you forward. The concern in the running world has long been that too much of one or the other spells trouble, but the research tells a more nuanced story.

Many runners and people in the fitness world believe that pronated feet are associated with an increased risk of injury. However, this isn’t necessarily true. A study performed by Nielsen examined 730 runners all wearing the same neutral running shoe and found that runners with pronated feet actually had the lowest injury rates, while those with highlypronated feet were associated with the highest injury risk.

In other words, just because you’ve been told you have pronation in your feet doesn’t necessarily mean your foot structure is the cause of your injury. The relationship between arch type and injury is far weaker than most people assume.

Shoes

Many runners go to specialty stores where staff watch them walk or analyze the structure of their feet in order to prescribe a specific type of shoe, often a stability or motion-control shoe for pronators. This raises an important question: does prescribing shoes based on foot structure actually affect injury rates?

When we look at the research, studies have found that this practice does not appear to meaningfully influence injury rates. Matching a shoe category to an arch type, the foundation of how running shoes have been sold for decades, simply hasn’t held up well under scientific scrutiny.

That said, there’s something to be said for the placebo effect. Research shows that runners may report positive outcomes with orthotics or running shoes even when there’s no evidence those products truly help with injury prevention. Feeling confident and comfortable in your gear has real value, even if the mechanism isn’t what the marketing claims.

What Does This Mean for Me?

Rather than spending money on the most expensive shoe or hunting for the “perfect” shoe for your specific foot type, focus on comfort. A growing body of research points to comfort as one of the most useful guides for choosing footwear. If a shoe feels good when you run in it, that’s a meaningful signal. Find a pair that feels comfortable, and stick with it.

It’s also worth remembering that your running mechanics play a far bigger role in injury risk than your shoe choice does. Once you’ve found a comfortable shoe, put your energy into the things that have the greatest impact, such as refining your running form, gradually building your mileage, allowing adequate recovery, and strengthening your body for the demands of running.
