In the days of Adam and Eve, I bet their feet were killing them walking around without shoes in all those sticks and tree stumps. So some smart soul created the shoe to allow us to walk and keep our feet protected. However, there are many people on their earth that could care less about that invention. They still prefer to walk around bare foot and feel the natural ground beneath them. In the south, many people walk around on gravel, rocks and train tracks bare foot and they love it. A city person wouldn’t be caught dead without their shoes so it must be a location thing huh?
