Manner of walking is an important part of human locomotion and can be described in terms of GAIT, STEP, and heel-and-toe. GAIT is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate. STEP is the distance covered by a single movement of the foot from one point to another. Heel-and-toe is a type of walking where the heel of one foot touches the toe of the other foot as it moves forward.
