NATURAL UPPER MATERIALS
Smooth Leather has a very fine grain so the surface feels smooth. It is a sturdy material that is easy to clean either with a leather nourisher, polish or simply with a slightly damp cloth to wipe any dirt off. It has thickness of 2.8 to 3.2 millimetres and is characterised by its high durability.
Many can detect suede due to its fuzzy, soft, velvet like finish that is comfortable on the skin. The breathable, matte outer is thick however has a light weight feel. You may have to be slightly more delicate with this material by spraying the straps only (not the footbed) with a leather protectant and not pulling on the straps too hard as this may stretch the suede, making the straps lengthen.
Oiled/Waxy leather is obtained from tanneries and is coated with an oily or waxy surface coating. They have a visible grain and naturally occurring colour irregularities that are deliberately not removed in production, so that the natural matte surface of the leather is preserved. This particular leather marks easily and acquires a more rustic/stressed appearance. If you are after a smooth and unmarked leather, this material is not for you. If you would like to minimise this appearance, we suggest applying a leather conditioner or rubbing marks gently with your fingers.
Nubuck leather is made by sanding back the natural grain of the leather, giving the leather its fine structure. It has a softly brushed outer surface and textured appearance. As the nubuck is sanded from the outside, there may be some natural imperfections in the leather.
The metallic leather is a natural leather with a reflective film on the upper. As it has a foil like finish, it does scratch easier than other types of uppers therefore, customers will need to take more care or simply embrace the wear of them.

Birkenstock uses premium quality cork to deliver the orthopaedic contours that our feet require for ultimate comfort. The cork is a natural, lightweight, resilient and sustainable material.

After seven years of new growth, each individual tree is then ready for harvest. This cork that is used in Birkenstock footwear is completely renewable.
The latex used is mixed with cork in order to give the footbed more elasticity and flexibility.
