Uppsala Zip Shearling Suede Leather

The Uppsala Zip Shearling features:

• The suede upper 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. Suede is softer and more flexible by nature and does not have the same stability as smooth leather. The stability of suede also varies from hide to hide. This does not constitute a material or production defect.
• Natural leather insole 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.
• The cork footbed is a sustainable material extracted from the bark layer of the cork oak. This natural product is insulating and offers very good cushioning.
