Feet
Though the feet are described for their function of walking, they also take on much bigger meaning in this story. The different types of feet, “Black feet, Red Feet, Small Feet, Big Feet” are all a reference to the diversity of people one will meet and engage with in their lives. So the feet represent different kinds of individuals.
