Flat feet

Flat feet, or "fallen arches", are where your feet press flat on the ground. They're common and usually nothing to worry about.

Check if you have flat feet

To see if you have flat feet, check the inner sides of your feet while you're standing up.

A man's right foot placed flat on the ground. There is no gap between the foot and the ground.
If you have flat feet, your feet will be flat on the ground.
A woman's left foot with a raised area (arch) visible along the bottom of the foot.
You do not have flat feet if the inside part of your foot is raised off the ground (this is called the arch).

Flat feet do not usually need to be treated

You do not need to do anything if you or your child have flat feet and they're not causing any problems.

Most children have flat feet until they're about 6 years of age. After this time, they usually develop an arch.

Flat feet:

  • do not usually cause any problems
  • should not stop you doing any activities, including sports
  • are rarely a sign of anything serious

But sometimes, you may have pain around your ankle or the arch of your foot may ache. Your shoes may also wear out quickly.

Non-urgent advice: See a GP if you have flat feet and:

  • your feet are painful, stiff, weak or numb
  • you often get feet or ankle injuries
  • you have problems with walking or balance
  • you did not have flat feet before
  • it only affects 1 foot

These problems mean you might need treatment.

Treatments for flat feet

If flat feet are causing problems and you need treatment, a GP may refer you to a specialist like a podiatrist or physiotherapist.

Referral to a specialist is not available everywhere and waiting times can be long.

Your GP might be able to give you advice about paying to see a specialist privately.

A foot specialist can offer advice about:

  • what shoes to wear (wide, comfortable shoes with a low heel are usually best)
  • shoe insoles to support your feet
  • foot stretches and exercises
  • painkillers

These will not change the shape of your feet, but can help with things like pain or stiffness.

Surgery for flat feet

Surgery is rarely needed for flat feet.

It might help if there's a problem with the bones, tissues or muscles in your feet and other treatments have not worked.

Your GP may refer you to a surgeon if they think surgery might help.

Causes of flat feet

There's often no obvious cause for flat feet. It might just be the way your feet are.

Sometimes flat feet run in families.

Rarely, flat feet may be caused by:

  • the bones in the feet not growing properly in the womb
  • stretching of the tissues in your feet (possibly as a result of things like an injury, getting older or being overweight)
  • conditions affecting the muscles, nerves or joints in the whole body like cerebral palsy and spina bifida
