Flat feet affect most children but nearly all will grow out of it by the time they turn five.


What are flat feet?

If you are looking at the sole of your child’s foot, you may see that there is no arch on the inner side – this should extend from the heel to where the big toe starts.


Almost all children have flat feet until around age 5. Approximately 1:5 children will never develop an arch.

Of this 20% of children with flat feet after the age of 5, the majority will never have any problems from them.


If the feet are painful or stiff, only one foot is affected or if your child regularly sprains their ankle it is usually best to get an orthopaedic surgeon to assess their feet as sometimes there is an underlying reason for the flat feet that can be treated.

A doctor can carry out a physical exam and may suggest X-rays to rule out any underlying issues with the hip or knee joints.


As many children will grow out of flat feet, often no treatment is needed. However, a small minority may experience some pain and therefore there are a few options to consider:

  • Physiotherapy
  • Stretches
  • Supportive shoes
  • Arch supporting insoles

It is important to be assessed to ensure that you are recommended the correct insoles or supports, as the wrong ones may increase the discomfort


In a small handful of cases, surgery may be suggested. For example, if the flat feet are caused by fused foot bones (tarsal coalitions). This is usually only recommended if initial treatment such as insoles or physio have failed to improve the symptoms.
