The exterior of a pointe shoe is covered with fabric, thus concealing the box and other internal structural elements and lending an aesthetically pleasing look to the shoe. Most pointe shoes are covered with satin, but some are available with canvas exteriors. Pointe shoes are most often available in light pink colors and less commonly in black and white. When other colors are desired (e.g., to match a costume), pointe shoes may be dyed or, if available, ordered in custom colors.
