Flat feet is the term given to the condition when the foot’s arch has collapsed; the result being the entire (or almost entire) sole of the foot rests on the floor. While the lack of an arch itself does not hurt, flat feet can cause pain in your ankles or knees. The reason for this is pronation. Pronation is a condition where the heel bone angles inward and the arch tends to collapse; so in the case of a flat foot, it makes the condition even worse. As pronation gets worse, as will other complications of flat feet, such as the aforementioned ankle and knee pain.
Simply enough, arch support or orthotics are proper treatment for flat feet, and canhelp prevent complications from the condition.
