The natural leather that we use is mostly smooth leather, in some cases tumbled leather. This type of leather has many special characteristics, such as breathability, adaptation to the shape of the foot and durability.
Upper material: Suede
Suede is a split leather with a napped finish. It has a velvety surface and is very soft to the touch. It also boasts a high moisture absorption capacity.
Insole: Suede
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.
