Ankle pain is often directly due to injuries such as sprains, strains, osteoarthritis, and tendonitis.
This pain may also be related to the instable structure of your feet.
Excessive stress may be put on certain areas of the ankle due to lack of proper support and alignment.
Ankle pain is related to the spacing between the joints as the foot moves and turns. As the foot rolls inward, the joint spacing on the outside of the ankle is decreased. The ankle rolling outward results in minimized space on the inside of the ankle.
This rolling of the foot is from misalignment due to lack of proper fitting support or pronation (natural tilt of your foot that rolls inward or outward). When this space is diminished, bones begin to rub and grind on each other.
If an insole designed to fix your alignment is not worn, arthritis can potentially develop.
