Upper: Textile material
Textile material made of natural fibers are extremely versatile. They can be printed on, dyed and easily combined with other materials. BIRKENSTOCK only uses high-quality textiles as upper material.
Microfibers are a very fine synthetic fibers that are extremely soft and shape-retentive. Because they are free of animal products they are used as the covering material for the lining of footbeds in vegan products, among other things.
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.
