Some of the rarest and most exclusive sneakers are the ones customized by artists. This pair of hand-painted Air Force XXVs was made by the artist Mache and features a portrait of Heath Ledger as the Joker from the 2008 blockbuster The Dark Knight. Mache’s work has garnered him an international reputation and a list of celebrity clients, including Jay-Z, Kanye West, and LeBron James.
