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.
Outsole: Super-grip
The super-grip sole is comprised of two components: a nonslip, oil- and grease-resistant outsole made of rubber and a shock-absorbing midsole made of light, flexible EVA.
