Flat Feet

Flat Feet - What it is

Flat foot does not usually cause problems.

"Do I have flat feet?" is a common question asked by patients.

You've probably come across or heard about the terms "flat feet" or "pes planus" (to apply the correct medical terminology). These terms are often used by patients, shop assistants and health care professionals, but what do they mean?

Typically, in a non "flat-footed" individual, the arch of th e foot is usually raised off the ground when the person is standing. If the foot arch is low or inexistent, the person is said to have "flat feet" or sometimes, "fallen arches".

Pes planus tends to be a very common condition in the Asian population with estimates suggesting that it occurs in around 1-in-5 individuals.

Flat Feet - Symptoms

Flat feet can only be truly identified while the individual is standing or walking. When someone with flat feet stands or walks, their inner foot or arch flattens. In addition, the foot may roll over to the inner side (this is known as excessive subtalar pronation).

Typically, the arches of children may not fully develop until the age of 10, therefore it can be difficult to assess whether they have flat feet until this age.

Flat Feet - Causes and Risk Factors

The risk of flat feet is often difficult to give a definitive answer as there are a number of contributing factors. Often there are hereditary factors involved which may contribute to having certain weak/tight muscles or ligament laxity. Also, poor footwear can play a major part in developing flat feet. For example, shoes that limit toe movement, such as high heels, can lead to flat feet in adulthood.

Flat Feet - Diagnosis

​Treatment of flat foot is only required if it is associated with pain in the foot or lower limb. If there isn't any pain, treatment is not indicated simply as a result of having a flat foot. However, in severe cases, treatment may be warranted in order to prevent any possible future injuries.

Flat Feet - Treatments

Treating flat feet:

Like all health-related issues, it's important to recognise the problem as early as possible since its severity tends to worsen with time. Early treatments tend to be less invasive and are often associated with better outcomes than treatment at more advanced stages.

It is important to remember that there is no blanket treatment. Treatment would focus on specific aspects or parts of the foot that require modification or healing. This may be achieved in a number of ways. Often the first line of treatment is non-surgical.

Specific exercises such as calf stretching exercises, can be used in order to stretch and lengthen the Achilles tendon and posterior calf muscles, which can be involved in the development of a flat foot.

Insoles or orthotics may be used to correct the flat foot deformity or realign the foot and lower limbs. Your podiatrist or doctor can provide further details on appropriate Insoles or orthotics.

Surgery is usually only considered when the patient fails to respond to conservative measures (such as those above). Depending on the patient's specific condition, possible surgical procedures may involve:

  • Lengthening of the Achilles tendon
  • Calcaneal osteotomy (surgical shifting of the heel bone), which may help to re-align the rearfoot
  • Reconstruction of specific tendons, such as the tibialis posterior tendon

Flat Feet - Other Information

If I have flat feet, does that mean that I'm going to get pain?

Contrary to popular belief, having flat feet does not necessarily increase the incidence of injury and it does not usually cause problems.

However, flat feet may put a strain on your muscles, ligaments and joints, which may cause pain in your feet, legs, hips and back when you stand or walk. Furthermore, individuals with flat feet may develop tired or aching feet after prolonged periods of standing or walking.
