Insoles provide extra foot padding and shock absorption, protecting you from injuries like shin splints. Read on if you need help deciding which type is right for you.

How foot structure and function can cause shin splints

Your feet act as shock absorbers for your body when you stand, walk, jump or run. Shin splints can develop when this shock absorption element in your foot is lost, putting strain on the parts around it.

The shape of the arches, mobility and strength of your feet can affect your shock absorption ability, which can determine how susceptible you are to shin splints. However, a problem with shock absorption is only one of the potential reasons why people develop this injury. Read about all the most common causes of shin splints in this article.

Overview of foot structure - the 3 foot arches

You have three arches formed by the bones of your feet and supported by ligaments and tendons. They are flexible, springy structures responsible for taking weight and absorbing shock during movement.

Two longitudinal arches

On each foot you have two longitudinal arches – one on the inside and one on the outside.

The lateral longitudinal foot arch runs on the outside of the foot and the medial longitudinal arch runs on the inside of the foot.

One transverse arch

The transverse arch runs across your foot or at right angles to the longitudinal arches.

The transverse arch of the foot runs across the width of the foot.

Foot arches and foot posture

The posture of your feet impacts the way you move. The most common changes to normal foot posture include flat feet, high foot arches and overpronation.

Flat feet (pes planus) and shin splints

How flat feet can cause shin splints.

‘Flat feet’ refers to a foot posture where the longitudinal arches of your foot collapse and drop down towards the ground. Meaning your foot arch loses its springiness, collapsing under your weight instead of supporting it.

This type of foot structure leads to more force than normal passing through to your lower legs from your feet. When this happens, problems like shin splints can develop.

There is a strong connection between flat feet and pain in your legs, pelvis, buttocks and lower back. Low-arched runners are also more prone to soft-tissue and joint problems such as lower back pain and knee pain.

High foot arches (Pes cavus) and shin splints

High foot arches can be a cause for shin splints.

High arches usually mean your inner foot arches are high, and the ball of your foot and the heel are closer together.

High arched feet are usually quite stiff and inflexible. With less movement in your foot, it can’t share and transfer the load efficiently.

This can reduce the shock absorbing properties in the foot and lead to increased load being transferred to other parts of the body. Runners with high-arches are prone to bone-related issues like shin splints and stress fractures in the shin and foot.


Overpronation is a foot movement pattern where your foot rolls excessively inward and your arch collapses during weight bearing.

Athletes with overpronation, particularly runners, have an increased risk of developing overuse injuries like mid- and forefoot pain, shin splints, leg and low back pain.

Foot Mobility

What is foot mobility? Foot mobility refers to how flexible, pliable and mobile your foot is. Good foot mobility can make it easier for you to take each step without creating too much pressure on any particular area.

Stiff feet

If your feet are too stiff, they can take your weight but can’t bounce back, spread the load or transfer it. A rigid foot leads to overload issues like stress fractures and shin splints.

Hypermobile feet

If your feet are too mobile (hypermobile), they will struggle to support your weight. Hypermobile feet can result in overstretching injuries or falls from a loss of balance.

Foot strength

If you have strength imbalances in your feet, forces travelling up to your shins will be uncontrolled and you will be more vulnerable to injuries like shin splints.

In hypermobile feet, you may need more support from stronger muscles, better shoes or insoles to make up for the lack of structural support from your ligaments.

Plantar fasciitis and patellofemoral pain syndrome can be caused by poorly supported feet.


What is an insole?

An insole, or shoe insert, sits directly beneath your foot in your shoe and can be taken out and replaced with new ones to suit your activities. They can be purchased online or from most pharmacies, department stores or foot clinics.

An effective insole or orthotic should provide enough support.

How do insoles work?

Insoles fit inside your shoes and support the arches of your feet. They also have a cushioning effect when you run. They can improve the fit of your running shoes, leading to more comfortable runs.

As mentioned before, studies suggest foot posture and poor arch support can cause lower limb pain.

Since the posture of your feet directly impacts the alignment of the rest of your body, and good alignment is key to healthy movement, it’s vital to keep your feet well positioned and supported when you run. Insoles may help with this.

How to choose the right insole?

Choosing an insole that supports your unique foot posture helps distribute your weight evenly along the sole of your foot.

Insoles work best when they fit snugly to the contours of your feet. If they’re too high, they can hurt your feet, and if they’re too low, you’ll be missing out on their benefits.

To help you pick the best type, find insoles that come in different sizes and firmness levels and start by choosing one that is closest to your foot’s arch height.

How do you know what’s the right level of support?

If you press down on the insole (preferably with your foot), it shouldn’t sink in. If there’s too much give, it’s probably not going to give you enough support. Keep trying more options until you find one that gives you firm, comfortable support.

Standard insoles vs custom orthotic insoles

Custom orthotic insoles are usually more rigid types of insoles and moulded to the shape of your foot. They are beneficial when you need a higher level of arch support that can’t be bought ‘over the counter’, or when standard insoles don’t fit your foot shape.

Although you can take them out of your shoes, custom orthotic insoles may not be as transferable to your other shoes as standard softer insoles.

So, what's the verdict on insoles? Do they help with shin splints?

If you look at the number of online outlets selling insoles, you will see insoles are big business! But is it just a fad, or do they work for shin splints?

Unfortunately, from a research perspective, we don’t have much for you. As mentioned previously, there are several studies suggesting that poor foot posture can cause lower limb injuries like shin splints. But there is very little research clearly suggesting that insoles can help for shin splints.

For now, we advise patients to try it and see. If it works, use it. If it doesn’t, lose it!

Best treatment for shin splints

It’s not always easy to know what to do about shin splints.

Insoles may support your foot arches and help improve body alignment, but they cannot fix your injury as a standalone treatment.

The best way to recover from shin splints.

is by working on your foot strength and mobility and restoring your whole-body alignment and function.

Other causes of shin splints, which we covered in our shin splints overview article, should also be considered alongside your rehab program. In this way, you know you’re covering all your bases.

The Exakt Health app helps you with this recovery process. It includes an evidence-based, step-by-step rehab plan for shin splints. You can download and use it immediately.

Prevention is key to staying injury-free. Whether you decide to use insoles or not, healing your shin splints for good is more about the type of rehab program you follow than the type of insoles you choose.
