Cinderella's glass slipper fell off of which foot?

Cinderella's glass slipper was specifically designed to fit her left foot, which is a key plot point in the story. When the prince searches for Cinderella after she leaves the ball, the slipper only fits her left foot, reinforcing her identity and connection to the prince. This detail is significant as it highlights the magic of the slipper and the unique bond between Cinderella and the prince, as it symbolizes her true self and the love they share. The other options do not align with this detail from the story, as the slipper was never said to fit on the right foot or both feet.
