Combination of open-pored, flexible suede and high-quality, untreated natural leather.
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.
Because of its high elasticity rubber is very well suited for outsoles. Thanks to this property it supports the natural rolling motion of the foot. Rubber is also very robust and has good cushioning.
