What are rigid flat feet?

Christopher Chiodo, MD
Orthopedic Surgery
Rigid flat feet is a condition in which there is no arch to your foot, even when you are sitting. About one in 100 people suffers from an inherited condition known as tarsal coalition, in which two or more foot bones are fused together, limiting flexibility and flattening the arch. Many people have no symptoms. Some will develop pain in their teens. The pain may worsen with exertion.

Symptoms of rigid flat feet include:
  • Lack of an arch, even when no weight is on the foot
  • Pain that may start on the outside of the foot and extend up to the ankle
  • Pain that may intensify after walking or other exercise
