15% of adults have flat feet

Flat feet are characterized by a decrease in the plantar arch that is often associated with a valgus of the posterior area of the foot (valgus flat feet). It is common in children due to joint laxity, overweight or family history. In most cases, these are flexible, non-painful feet that are considered variants of normal.

What is involved in flat feet?

Flexible flat feet are present in most children and in approximately 15% of adults; only 1% of these become symptomatic. The plantar arch develops as the child grows.

The presence of a flexible valgus flatfoot does not affect the ability to walk, run or play.

Is it necessary to treat flat feet?

It is well established that flat feet do not require any medical or surgical treatment in most cases. Shoe modifications or insoles are ineffective and can only make the child uncomfortable. It is preferable to use a good shoe, with a flexible sole, posterior reinforcement and an internal plantar arch.

On the other hand, the pediatric orthopedist will treat cases of rigid, painful or very severe flat feet.

Can flat feet lead to other pathologies?

The infantile flat feet in the context of hyperlaxity improves with growth and does not derive in other pathologies but it is important to diagnose those cases of rigid flat feet that do not improve with growth and limit the function and/or mobility. The pediatric orthopedic surgeon will assess those cases of stiff, painful or severe flat feet.
