Flat feet can be caused by:
- Genetics, being born with flat feet – children are born with flat feet
- Tarsal coalition – a condition where the joints bridge or grow together restricting movement of the joint
- Accessory navicular bone – an extra bone that can cause weakness and support of the medial arch
- Ligament laxity – Marfan Syndrome
- Overall health of patient – obesity / diabetes
