Oiled Leather birkenstock has a visible grain and naturally occurring colour irregularities that are not removed in order to preserve the matt surface.
The quality can also be seen in our choice of leathers birkenstock. These leathers birkenstock can be recognised by the typical grain and colours that are visible on the surface. We do not try to hide these features; rather we maintain the individual characters of the natural surfaces. We deeply dye and permeate the leather birkenstock, instead of covering it up. This allows it to keep all of its valuable, natural properties, such as breathability, longevity and durability.
With continued use, the changes in the surface, such as a fine patina, creases and wrinkles become visible. There is also a so-called pull-up effect. This means that the colour nuances of the leather birkenstock depend on the type of stress it is exposed to. These characteristics are not quality errors, rather they are a sign of a true natural product, giving each Birkenstock® item an unmistakable, natural character.
