Birkenstock Women's Arizona Birko-Flor Sandal

The Birkenstock Arizona Birko-Flor Sandal is the iconic two-strap open-toe slide in Birkenstock's signature Birko-Flor synthetic upper material, available at Costco in colors including Black and Dark Brown.

The sandal features adjustable suede straps with felt-lined backing for a comfortable, customizable fit. The contoured footbed provides anatomical arch support, and the lightweight EVA outsole delivers durable shock absorption for all-day wear. The upper is constructed from faux leather (Birko-Flor), and sizing follows European sizing conventions: Euro 37 corresponds to US 6–6.5, Euro 38 to US 7–7.5, Euro 39 to US 8–8.5, Euro 40 to US 9–9.5, and Euro 41 to US 10–10.5.

Care instructions recommend wiping with a damp cloth and avoiding extreme heat. The sandal is imported and sold online only at Costco while supplies last, with a limit of 10 per membership.
