Your feet arch shape doesn't determine whether you can go barefoot. It's a myth. In fact, study after study says it has absolutely no bearing on whether you can go bare or not. Your feet arch, like your fingerprint, has its own unique shape.
We could find no correlation in the scientific studies between the shape of the feet arch and how it functions. However, what we did find is that the shape of the arch changes as you go barefoot. Yo start to strengthen the arch, and it grows taller. In essence, you're building a stronger spring. However, for many people, after the arch grow taller, the foot gets more muscular and better padded, and so, like the greatest African barefoot runners, the foot fill out and appear to be flat again. But this time the muscle is hiding a beautiful strong arch on the inside.
