Flexible Flatfoot

Flexible flatfoot is a common type of flatfoot in which the foot is flat while standing, but the arch returns when sitting or reclining. The condition usually affects both feet and starts in childhood or adolescence, becoming more severe through adulthood. While flexible flatfoot is often painless in the early years and can resolve on its own, it also can cause inflammation and stretching or tearing of the tendons and ligaments if it progresses.
