Yes, I basically only wear shoes outside, so my arch is barely pronounced. I've cut my feet by accident on glass, stubbed toes, and magically not gotten tetanus (hey, one more thing being barefoot can do to you.)
Sorry, but the issue is simple, before mankind discovered clothing, fire, sanitation etc. there lifetimes were shorter and shorter. Throwing back to barefoot running probably does feel more comfortable after a while, ignoring the occasional bloody cut and disease you may or may not grow immunity against. Have fun, I won't try and discourage you, oh wait, I will. I'll have to pay a share for your fucking healthcare when your feet give after years of abuse and you have to see a podiatrist.
