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. The upper is made from high-quality, untreated cowhide and natural leather. Thanks to the natural color gradient of the hides, no two shoes are the same. You are buying a unique item, with even the right and left shoes exhibiting differences in coloring.

INSOLE: SUEDE
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.

OUTSOLE: EVA
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.
