Most people’s feet have a gap where the inner part of their foot (the arch) is raised off the ground when they stand. The height of this arch varies.
Some people’s feet, however, have a low arch or no arch at all, which is referred to as flat feet or fallen arches.
When someone with flat feet stands, their inner foot or arch flattens, and the foot may roll over to the inner side (known as over-pronation). See Flat feet - symptoms for more information
Some people with flat feet never have any trouble or pain. Others may suffer from aching feet, or find that it puts a strain on the connecting ligaments and muscles, which causes pain in the leg joints when walking.
Who is affected?
Flat feet can run in families. It can also result from a problem such as arthritis or a ruptured tendon (see Flat feet - causes for more information).
What to do
It is usually not necessary to see your GP or podiatrist about flat feet.
Wearing supportive well-fitted shoes can relieve any aching caused by flat feet, and insoles and orthotics can take pressure and pain away from the foot arch if your feet over-pronate (see Flat feet - treatment for more information)
Surgery is generally not helpful for most people with flat feet.
