Birkenstock Arizona Sandal vs Keen Elle Backstrap Sandal

The Birkenstock Arizona is the safer pick for most adults: a contoured cork-latex footbed that molds to the foot, adjustable dual buckles, and a long track record backed by 11,000 ratings at 4.5. The Keen Elle Backstrap is a lighter, sportier, washable sandal with a hook-and-loop back strap and a non-marking rubber outsole, but it has far fewer reviews and a narrower fit story. Buy the Arizona for all-day standing and arch support; buy the Keen for active, water-adjacent, easy-on wear.

• Choose the Birkenstock Arizona if you want molded arch support, a custom-molding cork footbed, and a two-buckle fit you can dial in.
• Choose the Keen Elle Backstrap if you want a lightweight, washable, quick-on sandal with a secure back strap for active summer days.
