The writer and zoologist Desmond Morris observed that our feet communicate exactly what we think and feel more honestly than any other part of our bodies. Why are the feet and legs such accurate reflectors of our sentiments? For millions of years, long before humans spoke, our legs and feet reacted to environmental threats (e.g., hot sand, illtempered lions) instantaneously, without the need for conscious thought. Our limbic brains made sure that our feet and legs reacted as needed by either ceasing motion, running away, or kicking at a potential threat. This survival regimen, retained from our ancestral heritage, has served us well and continues to do so today. In fact, these age-old reactions are still so hardwired in us that when we are presented with something dangerous or even disagreeable, our feet and legs still react as they did in prehistoric times.
