Japan’s UNITED ARROWS has been running up the numbers this season in terms of its exclusive footwear releases, and now it’s clearing out space for another bespoke offering with the folks over at Birkenstock. Together, the two parties follow up on its collaboration with KEEN to join hands on a clean variation of the Arizona entitled the “Big Buckle” variation.This newest take is understated in every sense of the word. The dual-strapped uppers are manufactured with smooth black leather materials, and come fastened witha pair of oversized buckles on each foot, all of which are given with metallic silver finishes. The instep also sees through to a stealthy backdrop, but ushers in a notes of contrasting due to the pure white Birkenstock branding and sizes that are situated towards the center. Riding down underneath all of that is a full EVA foam outsole that continues the pair’s darker motif with the all-black aesthetic.If you fancy this versatile Arizona colorway, you can find them available for reservation right now via the United Arrows online store.
