A person with flat feet (fallen arches) has low arches or no arches at all. Most cases don't cause problems and treatment isn't usually needed. The arch, or instep, is the inside part of the foot that's usually raised off the ground when you stand, while the rest of the foot remains flat on the ground. Most people have a noticeable space on the inner part of their foot (the arch). The height of the arch varies from person to person.
Over-stretching or tearing the arch pad causes the dull ache that is associated with arch pain. Pain is most keenly felt when weight is put onto the foot, or when pushing off the foot into the next stride. The pain of foot arch strain can be particularly acute after sitting for a long time, or when getting up in the morning. Those most susceptible to the condition are people with very high, rigid arches. The injury is also common in middle-aged people who have been inactive for a long period of time before suddenly increasing their physical activity. The injury is particularly common in runners and joggers.
Symptoms of arch pain and arch strain are found in the underside of the foot, where the foot arch is. Arch pain and arch strain is actually inflammation of the tissue in the midfoot, formed by a band that stretches from the toes to the heel. The arch of the foot is needed for the proper transfer of weight from the heel to toe. When the band forming the arch of the foot or plantar fascia becomes inflamed, it becomes painful to perform simple tasks.
Flat feet are easy to identify while standing or walking. When someone with flat feet stands, their inner foot or arch flattens and their foot may roll over to the inner side. This is known as overpronation. To see whether your foot overpronates, stand on tiptoes or push your big toe back as far as possible. If the arch of your foot doesn't appear, your foot is likely to overpronate when you walk or run. It can be difficult to tell whether a child has flat feet because their arches may not fully develop until they're 10 years of age.
Non Surgical Treatment
High arches that are flexible do not require any treatment. In cases where there is pain, shoe modifications such as an arch insert or support insole can help to relieve pain during walking. Custom orthotic devices can be given that fit into the shoe and provide stability and cushioning effect. Your doctor may recommend a brace to help keep the foot and ankle stable. In severe cases, surgery is performed to flatten the foot. Any coexisting nerve disorders are also treated.
In rare cases, surgery may be needed if a child has flat feet caused by a problem they're born with (a congenital abnormality). The foot may need to be straightened or the bones may need to be separated if they're fused together. Painkillers and insoles are the first treatment options for flat feet that are caused by a joint problem, such as arthritis or a torn tendon. However, surgery may be recommended if the injury or condition is severely affecting your feet. Where flat feet are caused by a condition that affects the nervous system, special shoes, insoles, or supportive foot or leg braces may be needed. Again, in severe cases, an operation may be needed to straighten the feet.
Below are two simple plantar fasciitis stretching exercises to help improve the flexibility of the muscles and tendons around the foot and ankle. Plantar fasciitis stretch taken from The Stretching Handbook. Kneel on one foot and place your body weight over your knee. Keep your heel on the ground and lean forward. In the photo to the left, the athlete is stretching the arch of her left foot. Kneel on one foot with your hands on the ground. Place your body weight over your knee and slowly move your knee forward. Keep your toes on the ground and arch your foot. In the photo to the right, the athlete is stretching the arch of his right foot.
