You can think it's crazy but I've always been barefoot my whole life. I grew up with my mother who is in the hippie culture and thinks human have to be barefoot. I've always lived in the warm south and go everywhere with no shoes without any problems. I'm now in my twenties and I don't know how it feels to have shoes or socks on. I can't imagine my feet not touching the ground when walking.
In few months, I plan to travel the country and I fear the moment I'll have to wear shoes because of the temperature.
