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

- you often get feet or ankle injuries
- you have problems with walking or balance
- you did not have flat feet before

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
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.
