Flat Feet

Formation of Pediatric flat foot is quite common in infants owing to baby fat which apparently conceals the developing arch. Moreover, diagnosing flat foot at a young age is quite difficult. Hence, parents and elders are advised to keep their eyes open and personally examine their wards from time to time if they see them complaining of pain in foot region consistently.

On the other hand in case of adults, flat feet is mostly the result of an injury, illness or continuous state of stress on the foot. Flawed biomechanics is another possible reason cited for flat feet in adults by medical experts. Women, especially during pregnancy are most susceptible to this form of foot deformity.


The most effective way of detecting flat feet in both adults and kids, is by wetting the foot. This traditional wet footprint test sees the candidate standing on a smooth surface for some time. After he /she leaves the place, the footprint is examined. The degree of foot flatness is determined by the contact area of his/her sole with the surface.
