Are my child’s flat feet normal?
Almost all infants have flat feet until they are around three years of age. This is believed to be due to two factors. Firstly, children have loose ligaments which allow the arches to collapse. Secondly, children have a pad of fatty tissue which sits in the foot and hides the arch. After 3 years of age, as your child gets stronger and less bendy and the fat pad resolves, arches begin to appear. A child’s arch is fully formed at 10 years of age. Often, you can see your child’s (hidden) arch before this. Try asking your child to stand on their tippy toes (or hold a favourite toy out of reach). When your child stands on tippy toes you should see an arch form. You may also see an arch in their foot when they are sitting with their feet dangling.
Whether your child develops an arch or not is genetically determined. A significant number of adults have flat feet and most will have no pain or complications. Children without arches do not generally need insoles or special shoes and research has shown that insoles will not help an arch form. Your child’s foot shape is genetically determined.
