What is pronation

What is over/under pronation?

Pronation is the word used to describe the natural movement of the foot, whereby the foot “rolls” slightly, flattening the arches to distribute the weight evenly across the foot. This is your body’s natural shock absorber, it helps the lower leg deal with shock. Your foot should normally roll a bit inward with each step. However, some people pronate more (overpronation) or less (underpronation) than others.

Symptoms

With overpronation, your foot rolls inwards more than it should. This means your lower leg absorbs more impact than it has to and your foot and ankle have problems stabilizing your body. It also means that the front of the foot at the big toe is working harder than it should. The front of your foot will push off the ground using mainly the big toe and second toe, which then has to carry all of your body weight.

 

With underpronation (supination), your foot does not roll inwards enough. This means the full impact of each step is concentrated on a smaller area of the foot (along the outside edge) and is not distributed as efficiently. This also means that most of the work pushing your foot off the ground again is done by the smaller toes on the outside of the foot. This movement puts extra stress on the Plantar Fascia, Achilles tendon, and IT Band which can lead to further injuries in these areas.

What causes over / under pronation?

Overpronation and supination is usually a result of an inherited problem with the structure of your foot. In other words, if you are an over or under-pronator, it is not the result of an injury, but rather caused by the height of your arch and your “gait cycle”. People who underpronate tend to have high arches while people who overpronate tend to have little to no arches.

However, either may be worsened or become more exaggerated as a result of weakness in certain muscles or your foot, ankle and leg. This lack of strength could be a result of:

    • Inadequate shoes
    • Misalignment of the body
    • Prior injury to the foot that damaged your tendons or muscles
