In the course of normal use, there are three predominant types of wear on a pointe shoe that will determine its useful lifetime. The most important of these is shank wear. As the body of the shoe is repetitively flexed, the shank gradually weakens and loses its ability to provide support. A pointe shoe is no longer serviceable when the shank breaks or becomes too soft to provide support. The second is the softening of the box and especially the platform on which the dancer balances.
