A lot of times, especially when we don't spend any time barefoot on uneven surfaces, we let our feet go "splat" with nothing really supporting or aligning our bodies below the ankle. That leads to all kinds of problems further up the chain.

This is all stuff I learned the hard way. They put me in foot orthotics when I was six years old rather than try to find shoes that fit my flippers. I've come a long way in the past few years, but there's 40 years of weakness and rigidity to undo, and it's taking time. If you had bones fused during your surgery there may be a limit to how much your feet can do, and you may need to rely on orthotics to some extent, that's why I asked about PT.
