Overview
The arch of the foot is made from a complex series of bones tendons and ligaments. According to podiatric practice there is only one important arch of the foot on the medial side. The height of the arch varies and having a flat foot or high arched foot is inherited. The arch acts to dissipate forces and store energy within the foot. Most young children have flat feet and this is because the arch has fatty tissue overlying it. Normally an arch appears after the age of 5-6 years. Even if you remain flat footed this might be normal for you and your family. Just because the arch is low does not mean that any treatment is required. Many world class athletes have flat feet. If the arch is painful or the arch of one foot suddenly drops then investigation and treatment may be required. The arch might drop acutely due to a tear in a tendon or the movement of a bone within the arch. A scan and X Ray may be indicated and treatment ranging from insoles to surgery may be required. If you have a high arched foot this is likely to have been inherited. In extreme form this can cause pain in the ball of the foot and is often associated with a tight Achilles tendon and a tendency to walk on the outside of your foot. In most people there are no symptoms and in others there may pain along the arch and pain on the outside of your ankle. Both these foot types are often mild and require no treatment, but if symptoms occur a full bio-mechanical examination will often reveal a mechanical cause to your pain. Often the treatment may be simple stretches and orthoses.


Causes
Spending a lot of time on your feet. Especially when you are not used to doing so. For example you may have started a new job such as waiting tables where you are on your feet all day and wake up the next day with sore feet. This is a sign of damage and over time could lead to plantar fasciitis. Being Over-Weight. Never an easy topic to discuss but in simple terms, the heavier you are, the greater the burden on your feet. There are times when you're walking when your entire body weight is borne on one leg and therefore one foot, placing great strain on the plantar fascia. Wearing shoes with poor arch support or cushioning. A tight Achilles tendon. This is the big tendon at the bottom of your calf muscles above your heel. If this is excessively tight this can affect your ability to flex your ankle and make you more likely to damage your plantar fascia. Suddenly changing your exercise routine. Using running as an example if you suddenly run many more miles than your are used to or change to a new running surface e.g. grass to tarmac - these factors can put excessive strain on the plantar fascia and lead to plantar fasciitis. All of these risk factors ultimately lead to a specific change in foot structure. The term given is over-pronation and this basically describes rolling in of the foot and lowering of the arches. It is this change that excessively elongates the plantar fascia which can lead to plantar fasciitis.

Symptoms
The majority of children and adults with flexible flatfeet never have symptoms. However, their toes may tend to point outward as they walk, a condition called out-toeing. A person who develops symptoms usually complains of tired, aching feet, especially after prolonged standing or walking. Symptoms of rigid flatfoot vary depending on the cause of the foot problem.

Diagnosis
Magnetic Resonance Imaging (MRI) can show tendon injury and inflammation but cannot be relied on with 100% accuracy and confidence. The technique and skill of the radiologist in properly positioning the foot with the MRI beam are critical in demonstrating the sometimes obscure findings of tendon injury around the ankle. Magnetic Resonance Imaging (MRI) is expensive and is not necessary in most cases to diagnose posterior tibial tendon injury. Ultrasound has also been used in some cases to diagnose tendon injury, but this test again is usually not required to make the initial diagnosis.

Non Surgical Treatment
Though most FFF are asymptomatic (no pain or discomfort), they should still be addressed as it is not normal to have flat feet. Obviously it is always ideal to prevent a problem rather than treat it after it occurs, especially if FFF is being treated post-foot development. As mentioned earlier, barefoot is the best way to prevent FFF and a host of other foot and gait imbalances. To truly strengthen the entire foot and all the arches, it?s important to position the foot correctly at all times so when wearing something on the feet, footwear should be flat, firm, and flexible. This means that the shoe should not have a significant, or any, heel to toe drop, there should be little to no cushion or padding in the sole, and the shoe should not be rigid anywhere - it should bend throughout the shoe and in any direction. The shoe should also be wide at the toe box allowing the toes to naturally splay apart.


Surgical Treatment
Cavus foot is caused in part by an over-pull of one of the lateral ankle muscles. A release of this tendon can be performed on the outside of the ankle. Additionally, a transfer of this tendon can be performed to help in correcting deformity of the ankle joint. Often patients will have a tightness of their gastrocnemius muscle, one of the main muscles in the calf. This can increase the deformity or prevent a correction from working. It is addressed with a lengthening of a part of the calf muscle or Achilles tendon. This is often performed through one or more small cuts in the back of the leg or ankle. Finally, the plantar fascia may be tight. The plantar fascia is a cord-like structure that runs from the heel to the front part of the foot. Partial or complete plantar fascia release may be done.


Prevention
There are several things you can do to prevent pain on the bottom of the foot. Here are some tips to help you avoid this condition. Do simple stretches each day (See Plantar Fasciitis Exercises for a list of all exercises). Wear good shoes that fit properly and are appropriate for the activity you are participating in. Lose excess weight if possible. Build your stamina slowly, especially with new exercises. Rest and elevate your feet, whenever possible, keeping them at least twelve inches above your heart. Always follow your doctor?s instructions for treatment. Each day do a different activity. For example: one day ride your bike, and swim the next day.
