Summary

Arizona is footbed-first: match Birkenstock EU, then pick Narrow or Regular. Official and major retailers treat length as TTS once EU is correct; some wearer guides still say size down when between EU sizes or when copying US sneakers — that split keeps Partial.

Fit depth guide

Conditional: (1) Know your Birkenstock EU → stay there. (2) Between EU sizes + slim foot → consider smaller length or Narrow. (3) Width pressure → Regular/Wide before changing length.

Leave a little toe/heel room by design. Cork molds over days — early pressure can ease without a new size. Versus Boston: closed toe changes volume; same EU logic.

Conditional depth (still Partial): Official and major retailers treat Arizona as TTS once you match Birkenstock EU — but the “size down” camp usually means (a) you are between EU sizes with a low-volume/narrow foot, or (b) you copied a US sneaker size without converting. Width is the real first decision: Narrow (often the default women’s footbed) vs Regular (medium–wide / most men’s). Length and width are independent — spilling over the rim is a width problem, not an automatic EU size-up. Leave ~5 mm toe / ~10 mm heel space by design; cork molds over 1–2 weeks, so early hotspots can ease without a new size. Versus Boston: same footbed family, enclosed toe changes volume feel.
