Generally, people with flat feet tend to overpronate, while people with high arches tend to supinate.
Best way is to check the soles of your current running shoes. If you were an overpronator, the outer sole of your shoes would be worn out along the inside, near the ball of the foot. If you were a supinator, the outer sole of your shoes would be worn out along the outer edge.
Alternatively, you could monitor your gait. You are:
- A pronator – if the arch of your foot flattens, when your foot strikes the ground.
- An overpronator – if you have a flat or a weak arch and your feet roll inward too much. It can lead to injuries and needs to be rectified.
- A supinator – if you more often than not stand on the outside border of your foot.
