Silver Shoes
In "It's Not Easy Being Green", shortly before "The Doctor", Zelena, the woman who would eventually become the Wicked Witch of the West, goes to the Wizard in order to seek out her family. Upon discovering that she was abandoned by her mother, Cora, and that her half-sister, Regina became Queen and was being trained by Rumpelstiltskin, the Wizard gives Zelena the shoes so that she can travel to the Enchanted Forest to try and replace Regina as Rumpelstiltskin's student. Upon being rejected by him, Zelena turns green with envy. She mocks Rumpelstiltskin with the power of the Silver Slippers, thus causing his later desire to obtain them. Using the Silver Slippers again she returns to Oz and dethrones the Wizard.
