The calcaneus, or heel bone, is magnificently designed for standing and walking, helping us balance over any kind of terrain. When we walk barefoot and with proper form, we land very lightly on our forefoot, or may even roll off the heel. The twenty-eight (28) bones in each of our feet work in harmony with our muscles to absorb shock and bounce back, This giant "spring" is one of the greatest marvel of the human body.
Landing hard on your heel, whether barefoot or shod, is harmful to the body, but a cushioned shoe gives you a false sense of security. Those cushy shoes lead your brain to the false conclusion that it's okay to land on your heel first ー you're protected. But that heel strike sends a shock wave straight through to your ankles, knees, hips, back, and neck. It's as if you're striking bone on bone, once the impact travels past the shoe, there's no stopping it.
