Since the 18th century, Birkenstock has been driven by one obsession: making footwear adapt to the foot, not the other way around. This led to its anatomical cork-and-latex footbed, which molds to body heat and weight until it becomes a personal footprint. The Arizona, with its two adjustable straps, arrived in 1973 and became the world's most recognizable sandal without changing virtually anything about its design.
Birkibuc is the synthetic material Birkenstock developed to imitate the feel and appearance of nubuck, with the advantage of being easier to clean and more resistant to moisture. The Stone shade —a cool stone gray— contrasts with the footbed's natural cork, leaving the layered construction that defines the model clearly visible.
Neutral Arizona shades are the first to sell out each season. At Next Step, you get them 100% new and authentic, with 14 calendar days for returns from receipt and fast shipping to Spain and throughout Europe.
Stone gray is a true neutral: it works with white, black, denim, and every earth tone. With or without socks, depending on the season and personal preference. Discover more models in Birkenstock at Next Step.
