Understanding Pronation

Understanding Pronation

If you’ve recently had an assessment with a Canadian certified pedorthist, they may have said you pronate, overpronate, underpronate, or supinate while you walk.

In this article, we will explain what pronation means and why it’s important for your gait.

What is Pronation?

Pronation is the natural movement of the foot as it rolls inward. This movement absorbs shock by distributing the impact forces generated from the ground.

Typically, there would be some splaying of the arch and some shifting of the ankle towards the inside, but the foot may not fully flatten on the ground; the amount of movement depends on the arch height and flexibility of the person.

There is a big misconception that pronation is bad, but it’s actually necessary for shock absorption during the gait cycle. It is easily mistaken for being the cause of foot pain as too much of it can cause malalignment. This is called overpronation.

Overpronation

Overpronating feet tend to fully splay and contact the ground. The ankle may also rotate inwards at a significant angle. This is where we start to see the effects on biomechanics as the knees and hips also start to rotate inwards and be misaligned. This can cause more pull on the surrounding soft tissue structures and hence put more strain on them to create pain over time.

Excess foot movement can also cause extra friction on various areas of the foot, which can result in pressure spots and callusing.

All of this can result in conditions like plantar fasciitis and patellofemoral pain syndrome, which can be controlled and supported by wearing custom orthotics and the proper footwear.

Supination

This term refers to the movement of the foot as it comes up from the ground after being planted, to allow the foot to propel itself forward. Normal supination is required to bring the foot back up, to prepare the body to take its next step.

Underpronation

We also refer to this as ‘oversupination’. When your feet underpronate, they are lacking in movement – in this case, the arch does not splay much. Because of this, the foot rolls towards the outside and doesn’t absorb shock as well.

Conditions such as plantar fasciitis and Achilles tendinitis can affect flat feet and feet that underpronate as well. However, it arises from increased tension buildup in the soft tissue. Due to the structure of the foot, pressure spots can also build up in the forefoot and heel. Therefore, orthotics made for these feet work towards a different purpose, which is to improve pressure distribution and cushioning.

This does not mean everyone with a high arch is a supinator, and everyone with a low arch is an overpronator. Someone can have very high arches and still overpronate when they bear weight or walk.

    I am experiencing pain in my left hip more so than
    before. My right leg is shorter, always has been.
    My feet are very comfortable with the orthotics.
    Will the hip pain right itself
