"Pes planus" is the medical term for flatfoot, a condition where the arch of the foot collapses or fails to develop. π¦Ά This means the entire sole of the foot comes into contact with the ground when standing. It can be flexible (arch appears when not standing) or rigid (no arch at all). Often, it's painless, but it can sometimes lead to discomfort in the foot, ankle, or even the knee. Think of it as the official, fancy name for something pretty common. Itβs just the Latin way to say flatfoot.
