text: Three types of foot posture exist in mammals: (1) plantigrade, in which the surface of the whole foot touches the ground during locomotion (e.g., human, baboon, and bear), (2) digitigrade, in which only the phalanges (toes and fingers) touch the ground, while the ankle and wrist are elevated (e.g., dog and cat), and (3) unguligrade, in which only a hoof (the tip of one or two digits) touches the ground—a specialization of running animals (e.g., horse and deer).
