ADER error’s Four-Piece Birkenstock Collaboration Embraces Snow Sport Tech Inspirations

Since its takeoff, the heritage German brand joined forces with the likes of Dior, Manolo Blahnik, Opening Ceremony, and, of course, Stüssy.


Birkenstock has been able to cater to a wide range of trends and feet thanks to its eclectic mix of collaborators, and it has now teamed up with ADER error of South Korea on a four-piece collaboration.

ADER error has opted to redesign the Birkenstock Gizeh, Arizona, Milano, and A630 PU Clog for the collaboration, adding a new “tech” moniker to the end of each shoe’s name. Because the main inspiration is based from winter sports, primarily ski boots, the “tech” element comes from ADER error’s personalization process.

The Gizeh, Arizona, and Milano models’ ratchet closures are inspired by the ADER error slogan “But near missed things,” and all four pairs come with a co-branded silicone pin in the shape of ADER error’s signature block logo. The streetwear brand’s classic “Z-Blue” hue is applied to the thong of the Gizeh sandal, which is made of nubuck leather before the Swiss-sourced fastener is added.


The Arizona, meanwhile, has a black-grain steer leather upper with the aforementioned strap, while the Milano has a soft, white-grain leather upper. The clog, as expected, is made of impenetrable materials that are resistant to water, oil, and grease. It also has a nonslip treaded sole and other features that meet strict hygiene standards.


The ADER error x Birkenstock collaboration will debut on the ADER error and Birkenstock websites on May 19, before hitting ADER error’s Korean retail locations on May 20 and select retailers worldwide on May 21. Take a closer look at the images in the gallery above.
