Flexible flatfeet are considered normal in young children because babies are not born with a normal arch. The arch may not form fully until sometime between ages 7 and 10. Even in adulthood, 15% to 25% of people have flexible flatfeet. Most of these people never develop symptoms. In many adults who have had flexible flatfeet since childhood, the missing arch is an inherited condition related to a general looseness of ligaments. These people usually have extremely flexible, very mobile joints throughout the body, not only in the feet. Flatfeet also can develop during adulthood. Causes include joint disease, such as rheumatoid arthritis, and disorders of nerve function (neuropathy). Unlike a flexible flatfoot, a rigid flatfoot is often the result of a significant problem affecting the structure or alignment of the bones that make up the foot's arch. Some common causes of rigid flatfeet include. Congenital vertical talus. In this condition, there is no arch because the foot bones are not aligned properly. In some cases, there is a reverse curve (rocker-bottom foot, in which the shape is like the bottom rails of a rocking chair) in place of the normal arch. Congenital vertical talus is a rare condition present at birth. It often is associated with a genetic disorder, such as Down syndrome, or other congenital disorders. The cause is unknown in up to half of cases. Tarsal coalition (peroneal spastic flatfoot). In this inherited condition, two or more of the foot bones are fused together, interfering with the flexibility of the foot and eliminating the normal arch. A rare condition, it often affects several generations of the same family. Lateral subtalar dislocation. Sometimes called an acquired flatfoot, it occurs in someone who originally had a normal foot arch. In a lateral subtalar dislocation, there is a dislocation of the talus bone, located within the arch of the foot. The dislocated talus bone slips out of place, drops downward and sideways and collapses the arch. It usually occurs suddenly because of a high-impact injury related to a fall from a height, a motor vehicle accident or participation in sports, and it may be associated with fractures or other injuries.
There are many reasons why flat feet develop. Here?s a look at some of the most common causes. Genetics, weak arches, injury, arthritis, diabetes, age, wear and tear on feet, tibialis posterior (ruptured tendon). Nervous system or muscle diseases such as cerebral palsy. Weakness and tightness of other muscles and tendons higher up in the lower extremity. The way our arches form depends on several factors. Our feet are complex structures that comprise twenty-six bones, thirty-three joints, and more than 100 muscles, tendons, and ligaments each. Each foot forms two arches. The arch that runs from the heel to the toe is known as the longitudinal arch, while the one that runs the width is known as the transverse arch. Ligaments (fibrous tissues) give our arches their shape and hold our bones together. The plantar fascia (the long, strong band of connective tissue that runs along the sole of your foot) and muscles add secondary support. There are also foot pads that absorb impact and assist with weight-bearing functions. How these things intertwine and work together determines the formation of our arches. A structural abnormality or injury to one of these components can result in flatfoot.
Arches can be seen as ?rolling downward? or collapsing when walking. Pain may present in lower back, hips or knees. Pain may be present on the bottom of the heels, within the arch, within the ankles or even the forefoot. Swelling can occur. Pain may occur in the anterior leg muscles.
An examination of the foot is enough for the health care provider to diagnose flat foot. However, the cause must be determined. If an arch develops when the patient stands on his or her toes, the flat foot is called flexible and no treatment or further work-up is necessary. If there is pain associated with the foot or if the arch does not develop with toe-standing, x-rays are necessary. If a tarsal coalition is suspected, a CT scan is often ordered. If a posterior tibial tendon injury is suspected, your health care provider may recommend an MRI.

Non Surgical Treatment
If fallen arches are not causing any pain or discomfort, then they will not need any treatment. If they were causing a persistent pain in the feet, or in the hips, legs or knees, then it would be best to consult your family doctor. Walking is the natural activity of feet and if it is not too painful, sufferers should walk as much as possible to strengthen their arches. When it is possible, go barefoot, or wear soft flexible shoes. In cases of severe fallen arches, your doctor may recommend special shoe inserts.
Feet that do not respond to the treatments above may need surgery. The surgery will help to create a supportive arch.
