I don't know if anyone else suffers from this problem? It is what used to keep men out of the army, still may do! If you look at an adult foot from the inside, you'll usually notice an up wards curve in the middle. This is called an arch. Tendons - tight bands that attach at the heel and foot bones - form the arch. Several tendons in your foot and lower leg work together to form the arches in your foot.

When the tendons all pull the proper amount, then your foot forms a moderate, normal arch. When tendons do not pull together properly, there is little or no arch. This is called flat foot or fallen arch.

Actually you can easily test yourself to see if you might have fallen arches or flat feet. Follow these three steps:

Get your feet wet.

Stand on a flat surface where your footprint will show, such as on grey concrete pavement.

Step away and look at the prints.

If you see complete imprints of the bottom of your feet on the surface, then you're likely to have flat feet.
Many young children have flat feet, a condition referred to as flexible flat feet. When the child stands, the feet look flat. However, when the child rises to his or her toes, a slight arch appears. In most cases, as children grow older, the arches develop.

Causes of flat feet and fallen arches can stem form various problems.
The most common ones are:

An abnormality that is present from birth
Stretched or torn tendons
Damage or inflammation of the posterior tibial tendon (PTT), which connects from your lower leg, along your ankle and to the middle of the arch
Broken or dislocated bones, some health conditions such as rheumatoid arthritis, nerve problems obesity, diabetes, ageing and pregnancy

Many people have flat feet - and notice no problems and require no treatment. However, others may experience the following symptoms:

Feet tire easily
Painful or achy feet, especially in the areas of the arches and heels
The inside bottom of your feet becomes swollen
Foot movement such as standing on your toes is difficult
Back and leg pain

If you notice any of these symptoms it's time to seek medical advice.

If you do go to ot the doctor, he will examine your feet to find out whether you have flat feet and what the cause is likely to be

He might check your health history for evidence of illnesses or injuries that could be linked to flat feet or fallen arches and he will probably look at the soles of your shoes for unusual wear patterns. He will observe your feet and legs as you stand and do simple movements such as raising up on your toes
·and will test the strength of your muscles and tendons, including other tendons in the feet and legs such as the Achilles tendon or the posterior tibial tendon. He might even take X-rays or an MRI of your feet
