We use different upper materials for our slippers and shoes.

Natural leather

Has a typical uneven grain and an alternating play of colours on the surface. These irregularities are not removed in order to preserve the natural matt surface.

Smooth leather

Has a fine grain and is slightly shiny. With its high elasticity it is tensile and wear resistant and well protected against external influences. It is easy to clean, durable and breathable.

Suede leather

Extra thick and very strong leather. Slight differences in structure are characteristic of real leather.

Nubuck leather

Has a velvety appearance because the natural grain of the leather is sanded.

Grained leather

Contains veins due to the use of a special tree bark optic.


Skin-friendly, tear-resistant and easy-care material. Can be cleaned with a slightly damp cloth. The top layer has a leather-like structure, the bottom layer is finished with a soft backing. Birkenstock has patented this material. If it comes into contact with the skin and heat and friction is created, Birko-Flor is less likely to cause blisters than plastic or synthetic material, for example. It is not without reason that Birko-Flor is frequently used in the production of Birkenstock, Birki’s and Papillio slippers. The material can therefore be found in many of our products. The biggest difference with leather is that the latter is more durable, more expensive and yet has a different look – it just depends on what you prefer. With slippers featuring Birko-Flor you will definitely find your feet.


Due to the special finish, this material looks like leather and feels like leather.

Birko felt

This is a combination of a wool pulp mixture and synthetic fibre felt. It is highly tear-resistant, breathable and skin-friendly.


Looks like fine nubuck leather. Is particularly light, very breathable, strong and skin-friendly. No leather is used in the microfibre models.
