Birkenstock Siena Women's Sandals NW/OB

The Birkenstock Women's Siena is a classic, refined sandal that brings an elegant, feminine touch to the brand's legendary comfort — distinguished by its crossed straps, which give the silhouette its unique and sophisticated look. The upper is crafted from incredibly soft suede, often finished with a subtle shimmer, or from high-quality nubuck leather that boasts a natural, rustic appearance depending on colorway, while a classic metal pin buckle allows for a fully adjustable, personalized fit across the instep. At the heart of the Siena is the original contoured Birkenstock cork-latex footbed — the construction thought out to the smallest detail that makes it feel like you're standing in sand — which creates custom support that molds to the unique shape of your foot with wear, supporting your health and promoting wellbeing through hours of all-day wear. The very deep molding in the heel area supports the foot tissue and holds the heel bone firmly in its natural position, providing nearly as much support in a sandal as in a closed shoe, while arch supports running alongside both sides of the footbed surround the tarsal bones inside and out to activate the calf muscles, stabilize the back of the foot, and improve gait and coordination. A natural leather footbed lining adds a refined, comfortable touch, and a lightweight EVA outsole grounds the sandal with cushioning and easygoing walkability. Built on a unisex construction in a Narrow (B = Narrow to Medium A/B) width, the Siena is made in Germany and fits true to size in a range of colorways including Black, Purple Fog, Aqua, and Sandcastle at an MSRP of approximately $130 — and because it comes in whole sizes only, ordering the next size up is recommended for half sizes. The Siena is also offered in a Soft Footbed version with an added foam cushioning layer, a Big Buckle version, a Flower embellishment version, and a vegan canvas version.
