Flat Foot

📖What is Flat Foot?

Flat foot, also known as pes planus, is a condition in which the arch on the inside of the foot is flattened or absent, causing the entire sole to come into contact or nearly into contact with the ground while standing. It is very common and often present from childhood as a normal variant that resolves as the arch develops with growth, though it can also persist into adulthood or develop later in life due to injury, tendon dysfunction, or age-related changes. In many people, flat feet cause no problems at all, while in others the altered foot mechanics lead to pain, abnormal gait, and secondary problems in the ankles, knees, or lower back. Evaluation focuses on distinguishing flexible flat foot, which is generally harmless, from rigid flat foot, which may indicate an underlying structural or neurological problem requiring further assessment.
