Fallen arches
"Fallen arches" is a common term used to describe a flatfoot condition that develops during adulthood. This should not be confused with other causes of flatfoot that may develop during childhood or adolescence. Most cases of “fallen arches” develop when the main arch-supporting tendon (the posterior tibial tendon) becomes weakened or injured, causing the arch to gradually become lower. With time, the shape of the foot changes and secondary symptoms start to appear. Common problems associated with fallen arches include plantar fasciitis, tendonitis, increased fatigue, and arthritis of the foot and ankle.
Test Yourself for Flat Feet
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 a concrete walkway.
-
Step away and look at the prints. If you see complete imprints of the bottom of your feet on the surface, surface you're likely to have flat feet
Flat feet in adults can arise from a variety of causes.
-
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, to the middle of the arch
-
Broken or dislocated bones
-
Some health conditions, such as rheumatoid arthritis
-
Nerve problems
