The Madalyn is handmade in Portugal with a leather upper that has a Velcro strap that looks like a buckle, we have found them to be a bit wider of a fit for the footbed than their traditional styles and their toe post is one single piece of leather that softens as you wear them! The unique SOFT-AIR technology integrated in the cork foot-bed of this ladies' toe post sandal guarantees an effortless walk. The AIR-RELAX technology respects the anatomy of the foot to prevent fallen arches.
