*Indicative price for a basic rubber flip-flop. Not verified against a specific SKU. **Marktplaats asking prices for lightly worn leather Arizonas run €49 to €70. Average across all Birkenstocks is €56. These are asking prices. Sold comps not yet pulled.
The honest line: the flip-flop wins the three-year cash comparison by €19. The margin is the smallest in any Dossier so far. The Arizona argument is the rebuild: a cobbler fits a new footbed for roughly €40*** and the sandal starts over.

Long-form (The Editor)
A rubber flip-flop has a design life of one summer. The strap tears at the plug, always at the plug, usually in week six.
Every trend list this year calls flip-flops "the most common summer essential." Seller margins run 45 to 60 percent. The product is engineered to be forgotten by September.
The Birkenstock Arizona is a different machine. Two leather straps, two buckles, a footbed of cork and latex on a jute core. The company has been making footbeds since 1774. The Arizona itself dates from 1973 and has survived every trend cycle since, including several that declared it dead.
The construction is the story. The footbed moulds to the wearer over the first hundred days. The sole is EVA, replaceable. The footbed itself is replaceable. A Dutch cobbler fits a new one for roughly forty euros. The leather upper, the part that carries the patina, stays.
The ledger, honestly.
A leather Arizona costs €95 on bol.com. A rubber flip-flop costs about €12. Over three years the flip-flop wearer buys three pairs, €36 gone. The Arizona owner spends €95 and can list the pair on Marktplaats for €40 to €70 lightly worn. Net cost: €55 against €36.
The flip-flop wins by nineteen euros. Three years is too short a race for cork.
Run it to ten summers. Ten years of flip-flops is ten pairs, €120, landfill throughout. Ten years of one Arizona is €95 plus two new footbeds at €40 each: €175. The cash gap narrows to €55 over a decade. What the cash number misses: a footbed shaped by ten years of your own stride. An orthopedic fit no new purchase can supply. Cork carries a memory. Rubber carries nothing.
This is the Darn Tough logic in a sandal. The product costs more per purchase and less per use. The Arizona at 200 wearing days a year costs under twenty cents a day before resale. Every rebuild resets the clock without resetting the fit.
Buy the leather. Wear it into shape. Rebuild it when it asks.
Verdict Card
The footbed takes a hundred days to learn your feet. Then it works for you for decades.
