'Flat feet' means the inner arch of the foot is low or flattened, so more of the sole touches the ground. It is extremely common — many people have flat feet for life and never have a problem, and children normally have flat feet that develop an arch as they grow.
The useful distinction is between flat feet that are simply your foot shape (flexible, painless — no treatment needed) and flat feet that are causing symptoms or changing over time (which deserve assessment). A particularly important situation is an arch that collapses in adulthood after previously being normal, which can indicate a treatable tendon problem. This page helps you tell these apart.
Most flat feet are painless. When flat feet do cause symptoms, these may include:
In children, flat feet are usually painless and normal; pain, stiffness or one-sided flatness are the features that warrant a look.
Flat feet arise for different reasons:
Sorting out the cause matters because harmless flat feet need nothing, while a collapsing adult arch benefits from early treatment.
See a doctor about flat feet if:
Seek prompt care for a hot, red, swollen or acutely painful foot/ankle, or foot problems with poor circulation or diabetes, which need timely attention.
At VinayakM, flat feet are assessed by:
The key questions the assessment answers are: is this causing a problem, is it flexible or rigid, and is a treatable tendon issue present?
Most flat feet need no treatment. When they cause symptoms, treatment is stepped and usually non-surgical:
1. Footwear and support:
2. Exercises and physiotherapy:
3. Activity and weight:
4. Pain relief:
5. Treating a collapsing adult arch early:
6. Surgery:
The great majority of people are managed comfortably without surgery.
At VinayakM in Greater Kailash-1, flat feet are assessed by Dr Udit Vinayak (trauma, sports medicine and joint replacement surgeon), with the first job being to reassure the many whose flat feet are harmless and to identify the few who need care:
You will not be given insoles or surgery for flat feet that do not need them.
You cannot change your basic foot shape, but you can reduce the chance of flat feet causing trouble:
Usually not. Flat feet are very common and in most people are painless and need no treatment. They only need attention when they cause pain, tiredness or difficulty with activity, or when an arch that was previously normal starts to collapse in adulthood. Painless, lifelong flat feet generally require nothing.
Most do not. Children normally have flat feet that develop an arch as they grow, and painless flexible flat feet in children usually need no treatment or insoles. Assessment is worthwhile if a child has foot pain, stiffness, or flatness affecting one side more than the other.
In some people, the altered foot and ankle alignment from flat feet can contribute to knee, hip or back discomfort, though the link is not automatic and many people with flat feet have no such problems. Where there is a connection, supportive footwear, orthotics and strengthening often help, as part of assessing the whole limb.
Not always. For many people with symptomatic flat feet, supportive shoes and good-quality off-the-shelf insoles are enough, alongside calf and foot exercises. Custom orthotics are useful for specific needs or particular foot shapes. An assessment can advise what is actually likely to help you rather than defaulting to custom devices.
Rarely. Surgery is reserved for specific situations — significant pain or deformity that has not responded to footwear, orthotics and physiotherapy, progressive adult-acquired flatfoot, or a rigid painful flatfoot. The great majority of people with flat feet are managed comfortably without any operation.
