What Is Flatfoot?
Flatfoot (pes planus) is a condition in which the arch of the foot disappears when a child stands, or when the entire sole of the child’s foot contacts the ground. In some cases, as the arch disappears, the child’s ankle also rolls inward (pronates).
There are two types of flatfoot:
- Flexible flatfoot: The most common form of flatfoot, flexible flatfoot affects both feet. It’s often a normal part of development (many children don’t develop arches until around age 10). Flexible flatfoot usually doesn’t cause pain or disability, and doesn’t require treatment.
- Rigid flatfoot: A rare type of flatfoot, rigid flatfoot affects both feet in roughly half of all cases. It often develops in children who have problems with the bones in their feet. Children who have rigid flatfoot might experience more severe symptoms, such as pain or cramping.
