The term that describes the movement of bending the foot towards the sole is plantar flexion. This motion occurs when the foot is pointed downward, such as when standing on tiptoes or pressing the gas pedal in a car. During plantar flexion, the angle between the foot and the leg increases, which allows for activities such as walking, running, and jumping.

Dorsiflexion, on the other hand, refers to the opposite movement, where the foot is flexed upwards towards the shin. Abduction and adduction describe movements of limbs or body parts away from or towards the midline of the body, which does not pertain to the foot's sole movement. Therefore, the focus on bending the foot towards the sole accurately defines plantar flexion.
