The Mobius Mule Hi offers a striking and modern take on the classic mule silhouette. The minimalist leather upper complements the sculptural heel, allowing it to be the focal point of the design. The open-back mule style offers effortless slip-on wearability. United Nude's launch product, the Mobius, was revealed in 2003 and has since become an icon in the world of design. The style was born from a conceptual development of the Möbius strip, a single-sided surface with no boundaries. Its distinct shape was inspired by transforming the frame of Mies van der Rohe's Barcelona Chair into a single band, uniting the upper, sole, footbed and heel into one infinite piece.
