Partnering for the first time, BIRKENSTOCK and ADERERROR borrow creative cues from snow sports to re-interpret the Gizeh, Arizona, Milano, and A630 PU Clog. Rendering each style with specialized and technical details, the collaboration unites German sensibilities with Korean accents. ADERERROR’s signature shade acts as a Z-blue thread through the collection, signifying the passion of youth, while select models feature a special tech closure sourced from Switzerland.
