Birkenstock Women's Siena HEX Nubuck Narrow Sandals
The BIRKENSTOCK Siena boasts a refined appearance. Crossed straps give the sandal its unique and special look. The upper is made from high-quality nubuck leather that boasts a natural, rustic appearance.
A Legendary Design
The heart of all models is the original BIRKENSTOCK footbed. The construction, which has been thought out to the smallest detail and makes it feel like you're standing in sand, helps your feet feel as comfortable as possible for hours on end. This supports health and promotes wellbeing.
Deep Heel Cup
The very deep molding in the heel area supports the foot tissue and holds the heel bone firmly in its natural position. This provides the foot with nearly as much support when it is in a sandal as when it is in a closed shoe.
Longitudinal Arch Support
The longitudinal arch support runs along the sides of the footbed, providing stability with each step.
Transverse Arch Support
The transverse arch support runs through the middle of the footbed, helping ensure proper alignment and a solid stance.
Raised Toe Bar
The raised toe bar encourages the natural gripping motion of your feet, exercises the legs, and stimulates circulation.
More Toe Room
A roomy toe box allows toes to move more naturally, promoting better balance and correct foot alignment.

Made in Germany
Nubuck leather has a gently buffed surface with no grains. As with velvet, brushing the surface of nubuck leather displaces the fibers and leaves a visible mark. Nubuck leather is very sensitive to moisture and color, and it therefore needs to be waterproofed.
Insole: Real Leather
The flexible leather lining, which is gentle on the skin, nestles up softly against your foot and adjusts to its contour. The open-pored and thus very breathable surface makes for a comfortable foot climate, even during more strenuous physical activity.
Footbed material: Cork
Cork is a sustainable material extracted from the bark layer of the cork oak. This natural product is insulating and offers very good cushioning.
EVA (ethylene vinyl acetate) is a high-quality, very light, elastic material with extremely good cushioning. As a result, it smooths out slight irregularities in the floor and ensures that every step is softly cushioned.
