In the story of Cinderella, her Fairy Godmother gives her the slippers, along with a ball gown and carriage, so she can attend a royal ball. Once there, she meets her Prince Charming. At midnight, when the magic wears off and Cinderella has to flee, she loses one of her slippers on the castle steps. The Prince discovers it and tries it on every girl in the kingdom until he finds his true love.
In an attempt to kill Phoebe Halliwell, as well as the other Charmed ones, the Wicked Witch killed the Keeper of the Fairy Tales and sent Phoebe the glass slippers. Phoebe tried them on, thinking that they were a gift from Cole. Immediately, her clothes changed into a ball gown and the slippers forced her down the street into a carriage. She is then taken to a charity ball, where she met Adam Prinze, who was under the spell of the Wicked Witch. He tried to kill her by forcing her into the carriage at midnight, which turned back into a pumpkin. However, before Adam could smash the pumpkin, Cole saved it. One glass slipper returned to the Fortress after Piper vanquished the Wicked Witch, though the other would only return once Phoebe found her "Happily Ever After". ("Happily Ever After")
