Pes planus is a condition in which the arch or instep of the foot collapses and comes in contact with the ground. In some individuals, this arch never develops while they are growing.
- Elongation of tendo achilles (procedure)
- Foot exercises (regime/therapy)
- Muscle strength exercise
If you have flat feet, your feet don't have a normal arch when you're standing. This can cause pain when you do extensive physical activity.
