What is pronation?
Pronation is the natural movement in which your foot tilts slightly inward after landing. This occurs in the joint just below your ankle and ensures that the impact of each step is absorbed.
Think of it as your built-in shock absorber: without pronation, every landing would hit much harder on your lower leg, knee, and hip.
'Normal' pronation ensures that you roll smoothly from heel to forefoot and can push off efficiently.
The different forms of pronation
Not everyone pronates in the same way. Roughly, there are three types:
1. Neutral pronation
Your foot tilts slightly inward (about 15%) and distributes forces well. This is the most efficient and injury-free way of walking.
2. Overpronation
Your foot tilts too far inward. This causes your ankle to sag slightly, creating extra stress on the inside of your foot and lower leg. This can lead to complaints such as shin splints, Achilles tendon problems, or knee problems.
3. Underpronation (supination)
Your foot tilts too little inward, meaning the shock is less well absorbed and the outside of your foot is extra stressed.
