It is a very common step in ballet. Bourree was a french folk dance which became a proper step in classical Ballet and has many variations. One is called "pas de bourree couru", because it is a walk on toes.
In the picture the girl in blu is doing the starting movement (demi plie) the second girl is raising the back leg into a coupe.....the step continues with another raising of the front leg and so on...
In Bharatanrityam we use a similar step, which is a walk on toes forward or sideways. It is called Vicyavaa and it is mentioned in the Natya Shastra in the Bhumi Chari chapter.
