Final answer:
Eversion occurs during the midstance phase of the gait cycle, when the foot is adapting to the ground and stabilizing weight distribution.
Step-by-step explanation:
Eversion is a movement involving the intertarsal joints of the foot, where the bottom of the foot is turned laterally, away from the midline. During the gait cycle, eversion primarily occurs during the midstance phase. This is when the foot adapts to uneven ground and aids in the distribution of body weight across the foot, preparing the foot for toe-off and ensuring stability.
