things you can do for flat feet

If you look at an adult foot from the inside, you’ll usually notice an upward curve in the middle. This is called an arch. Tendons – tight bands that attach at the heel and foot bones – form the arch. Several tendons in your foot and lower leg work together to form the arches in your foot.

you can easily test yourself to see if you might have fallen arches or flat feet. Follow these three steps:

Get your feet wet.
Stand on a flat surface where your footprint will show, such as on a concrete walkway.
Step away and look at the prints. If you see complete imprints of the bottom of your feet on the surface, then you’re likely to have flat feet.
Many young children have flat feet, a condition referred to as flexible flat feet. When the child stands, the feet look flat. But when the child rises to his or her toes, a slight arch appears. In most cases, as children grow older, the arches develop.
