Arch sandals are warm-weather styles built with a contoured footbed instead of a flat sheet of foam, aimed at shoppers who feel heel or midfoot fatigue after a day of standing.
- Footbed shape: look for a raised medial ridge and a defined heel cup rather than a printed arch outline.
- Material: cork and EVA mold differently, so check whether the bed softens with wear or stays firm.
- Strap adjustability: buckles or hook-and-loop let you tune volume over a high instep or a swollen foot.
Compare the listed insole length to a sandal that already fits, since arch placement shifts with size.
