Luke Castellan gave Percy Jackson his pair that had been given to him by his father, Hermes. However, they were cursed, in order to drag Percy down to Tartarus once he got to the Underworld.

Luke gives the shoes to Percy who then gives them to Grover because it would be dangerous for Percy to be in the air.

When they get to the Underworld the shoes try to pull Grover into Tartarus.
