I’ve read in a few places that the flat feet comes from wearing shoes that don’t allow your toes to splay, which causes the muscles that create the arch to atrophy. Not a scientist and have never had flat feet, so can’t confirm, but I recently started wearing zero drop shoes and definitely feel a healthy soreness as my feet get stronger.
Also when you run don't land flat-footed or heel-first. Land on the front part ("ball") of your foot, this lets your calf muscle absorb the shock, rather than sending the shock straight up your tibia into your knee.
This was a total game changer for me when running. I would always develop some sort of knee pain at some point but since making a very minor change to how I land my foot, I am running without any.
Make sure to start and transition slowly though as there are warnings about injuring your Achilles and other muscles in your calf if you start off too aggressively.
