Pain in the arch is common in those who stand all day especially to those overweight, and to those standing on hard surfaces. The strains that these condition place on the arch structure of the foot are great and eventually the foot can no longer resist the forces, resulting in arch pain. The most common cause of arch pain is plantar fasciitis, worst in the first few steps in the morning. Later in the day it tends to get worse. Other causes of arch pain include strains of the ligaments and joints of the midfoot region.
