Upper: Oiled leather
Oiled leather can be recognized by its untreated surface. BIRKENSTOCK purposely does not treat surface grains and other characteristic features. BIRKENSTOCK uses sturdy leather with a thickness of 2.8 to 3.2 millimeters as upper material.
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.
