The armadillo shoe (alternately armadillo heel or armadillo boot) is a high fashion platform shoe created by British fashion designer Alexander McQueen for his final collection, Plato's Atlantis (Spring/Summer 2010). Only 24 pairs exist: 21 were made during the initial production in 2009, and three were made in 2015 for a charity auction. The shoes are named for their unusual convex curved shape, which resembles an armadillo. Each pair is approximately 12 inches (30 cm) from top to floor, with a 9-inch (23 cm) spike heel; this extreme height caused some models to refuse to walk in the Plato's Atlantis show. American pop star Lady Gaga famously wore the shoes in several public appearances, including the music video for her 2009 single "Bad Romance".
