Both of your tarsal joints, which forms the arch, have been falling since you were a toddler; when you started to stand and walk on a flat surface unless your parents supported your arches with proper supports.

Because your body weight falls on the tarsal joint, the group of joints that involves 12 foot bones, which are arranged in a side-by-side manner. These joints fall if there is no support under the arch.

This means that your body has been growing and moving without the alignment since then.
