Toes on a
foot. The innermost toe (leftmost in image) is called the
big toe.
Toes are the digits of the foot of an animal. Many animal species walk on their toes, and are called digitigrade. Humans, and other animals that walk on the soles of their feet, are plantigrade; hoofed animals are unguligrade.
In humans, the bones of each toe continue all the way to the heel, although in from the base of the toes they come together in the body of the foot. The inside toe is by far the thickest, and is called the big toe, great toe, or hallux.
