Walking in bare feet is good for you, and paying attention to your feet can reap health dividends for your entire body:

"For most of us, our feet are not things that we pay much attention to. Women do when they paint and pamper and bejewel them, because pretty feet are a measure of feminine beauty. But healthwise, the only time we pay attention to our feet — as with many other parts of our body — is when they begin to hurt. The fact of the matter is that the human foot is such a complex and vital part of the human body that it has been called an organ. According to Chinese medicine, each organ in the body is represented — through around 300 nerves — to a specific point on each foot. Massaging these reflex points — a system of therapy called reflexology — is used to help stimulate vital functions, eliminate toxins, activate blood circulation and ease nervousness. In Ayurveda, the padabhyanga or foot massage is used to relieve insomnia, improve circulation and fertility, and energise the belly, pelvis and colon. "
