Question: What does it meen to be flat-footed?
Answers:
Yes, no arch. It's implications are unimpressive too. It doesn't exclude you from military service any more and it's not considered a problem that needs correcting every time, if your ankle rolls in you can get shoe inserts, if they don't then they don't usually do anything.
Going bare foot as a kid is the best exercise to improve your arches, but since kids don't notice feet anyway, parents should look out for it since it can be improved at an early age and that's better than not improving it - but either way it's not a life changer.
It means you don't have an arch in your foot or feet.
