Pes Planus (flat feet)
It is called the condition in which the arch of the foot is significantly reduced or even absent. The arch of the foot develops from the time a child begins to walk and is usually completed by the age of 8 years.
The pressures on the soles of the feet when the arch of the foot is reduced are different from those of a normal foot. Many times flat feet remain asymptomatic but others can cause pain when walking on the feet, knees and even hips.
