The sandal comes in black and light beige color options, and is accented by a silver-toned buckle that offers just a bit of customization for the fit of the straps. The criss-cross strap sandals are paired with the [ergonomic molded footbed](https://www.trendhunter.com/trends/vivobarefoot-vivobiome-tabi-gen-01-sandal) from Birkenstock in order to highlight an comfortable design that will accommodate all-day wear. The Birkenstock x BEAUTY & YOUTH 'SIENA' sandal features a slight tapering around the toes to make them an elegant yet ergonomic footwear style that's suited for an array of warm weather activities.
