Step 1 : Introduction to the question "On the human body, what is the hallux?"
...The hallux is the big toe on the human foot. It's the toe that is much larger and thicker than the other four toes on the human foot. The hallux plays a major role in dynamic and static activities involving the feet. Without a big toe, balance may be off. The human walking gait is best described as an inverted pendulum. Walking is low impact, meaning a heel strike begins the onset of each step. The hallux is instrumental in keeping the foot straight and guiding body weight forward. Source: BreakingMuscle.com
