Orthotics For Flat Feet For Adults With Flat Feet, Do The Shape An Adult's Feet Change Over Time?

For adults with flat feet, do the shape an adult's feet change over time? - orthotics for flat feet

I am an adult in my 30 years, it has been custom made orthotics for my flat feet. My straps are a little more than a year, but recently feel sore knee and calf. With time, how to change my feet when I have new versions of orthoses? I wonder if I could somehow recycle staples today that if my feet are in a different way.
