All Ungulates walk on the tip of their toes, or hoofs. This makes their legs longer, so they can run faster. Even when they are not running, they cover more ground with each step. This is important because many ungulates, including zebras, migrate to find water and food. Perrisodactyls are ungulates with only one toe or an uneven number of toes.
Zebras have only one toe.
The zebras closest relative is the horse. Their anatomy is almost exactly the same. Zebras and horses have a strap in their neck called the nuchal ligament. It is attached to the back of the skull and to long spines on the backbone. It helps keep their heads up and also helps lift the head up when zebra is feeding.
