Choosing Birkenstock Arizona sandals: materials, fit and sizing explained

Birkenstock Arizona sandals are popular as everyday sandals for women and men, as well as unisex sandals. But the range can be more complicated than it first appears. The difference between leather and Birko-Flor, choosing between a regular or narrow fit, and getting the size wrong can all affect how comfortable your sandals feel.

Before you buy, watch out for these common pitfalls:

  • Choosing based on colour alone: black, dark brown and basalt grey look different, but the material and fit have a greater impact on everyday wear.
  • Confusing leather with Birko-Flor: Birkenstock Arizona leather models have a natural leather upper. Birko-Flor is a synthetic material with a leather-like appearance and generally needs less maintenance.
  • Not checking your foot length before choosing a size: an adjustable strap won’t automatically make up for the wrong length or width. Check the size chart and see whether the model is available in a regular or narrow fit.

What features matter in Birkenstock Arizona sandals?

1. Choose between natural leather and Birko-Flor

A Birkenstock Arizona leather model has a natural leather upper. The dark brown and black models also have a suede lining and a cork footbed. Leather can change in appearance with wear and needs to be cared for with a suitable leather care product. Wiping it with a soft, slightly damp cloth is a good starting point; it isn’t suitable for machine washing.

Birkenstock Arizona Birko-Flor models have a synthetic upper. According to the product description, this material is tear-resistant and easy to care for. Dirt can be removed with a soft, damp cloth. Don’t use bleach or harsh cleaners. Bear in mind that these models may also have a leather insole or suede footbed lining. So, “synthetic” doesn’t mean every part of the sandal is synthetic.

2. Check the footbed and sole

The models in this selection have an anatomically shaped cork-latex footbed and an EVA sole. According to the product information, the footbed is designed to adapt to your foot as you wear it. This is a product feature, not a guarantee that every wearer will have the same experience.

The EVA sole is lightweight and flexible. When buying, check that the footbed visibly fits your foot well and that there’s enough room around your toes. A sandal shouldn’t be so short that your toes or heel extend over the edge.

3. Check the straps, width and size

The Arizona is a two-strap sandal. Both straps have a metal buckle, so you can adjust each one separately. This is useful if you want a different fit around your forefoot and instep.

For the available Birkenstock sandals in sizes 36 to 45, don’t rely on the EU size alone. The supplied size chart includes these guidelines:

  • size 36: foot length approximately 226–230 mm;
  • size 39: foot length approximately 246–250 mm;
  • size 42: foot length approximately 266–270 mm;
  • size 45: foot length approximately 286–290 mm.

The stated foot width varies by size. For size 42, for example, the stated width is approximately 93–107 mm. Measure both feet while standing and use the longer foot as your guide. If your feet are relatively narrow, look for a narrow-fit model too. An adjustable buckle doesn’t automatically make a sandal suitable for every foot shape.
