Special feature: Soft footbed
The soft footbed has an integrated latex foam cushion. So it offers excellent comfort from day one.
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: Natural leather
Natural 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.
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.
