Walking on your heels is called heel-first walking or heel-toe walking. This is the natural way in which humans walk as the heel touches the ground first.

Walking is an action, otherwise known as a verb.

When walking with walking sticks and walking canes you gain balance and upper body exercise. I don't know if it will induce labor, but I have always walked with my wife to help her through her pregnancies. Poles, sticks, staffs or canes can increasingly help one walk safely as the baby continues to grow and will help one tone up for the birth.
