Luke Castellan
A pair of magical sneakers that can sprout wings when the owner says, "Maia", the name of Luke's paternal grandmother. The sneakers were given to him by his father Hermes and bear a close resemblance to Hermes's own winged shoes. In The Lightning Thief, Luke cursed them into pulling the wearer of shoes into the pits of Tartarus; however, since Grover put them on instead of Percy it confused the curse. The shoes are now gone, for they slipped off of Grover and fell into Tartarus.
