The BIRKENSTOCK Siena boasts a refined appearance. Crossed straps give the sandal its unique and special look. The Big Buckle version features a large, elegant pin buckle – a striking accent on this otherwise understated sandal. The lining of the semi-exquisite footbed is covered with soft smooth leather and matches the shoe in color. The upper is made from extra thick, oiled nubuck leather.

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.
