What Is Foot Inversion?

Foot inversion is one of the most common causes of injury in physically active adults, and might have bigger impacts on your performance than you realise. To help you identify and overcome foot inversion we've written the definitive guide: What Is Foot Inversion?
Inversion and Eversion
Inversion refers to the tilting of the sole towards the midline of the body during movement. The opposite of this is called eversion, and refers to when the sole of the foot tilts away from the midline of the body during movement. If you think you may have foot eversion – or would like to learn more about it – you can read our companion blog: What Is Foot Eversion?
What Causes Foot Inversion?
Foot inversion usually occurs as a result of poor posture in the foot. Inversion can creep in subtly as a result of weak inversion and eversion muscles, and is often hard to catch before injury occurs.
What Are the Risks of Inversion?

In general, both foot inversion and eversion increase the risk of injury during intensive, repetitive physical activity. Another significant impact is performance; correct foot posture is vital to getting the most out of your legs and reaching new levels of athletic achievement.
Who Is Susceptible to Foot Inversion?
Both inversion and eversion can occur in anyone's gait, but are primarily of concern to those undertaking physical activities including:
