Children are born with flexible flatfoot, a condition in which the arch of the foot shrinks or disappears when you stand on it. Parents and other family members often worry needlessly that an abnormally low or absent arch in a child's foot will lead to permanent deformities or disabilities.
Most children eventually outgrow flexible flatfoot without any problems.
Does not interfere with walking or sports participation. Corrects itself over time without surgery or other treatment. A flexible flatfoot has normal muscle function and good joint mobility and is considered normal. As the child grows and walks on it, the foot's soft tissues tighten, shaping its arch gradually. Flexible flatfoot often continues until your child is at least age 5 or older.
