How Birkenstocks Support Your Feet

Arches

The Birkenstock footbed consists of four layers. Two layers of Jute provide the shoe with breathability, flexibility, and structure, a layer of suede is added for moisture absorption, and a final layer of cork and latex for support, shock absorption and comfort. 

These four layer are then formed into the famous Birkenstock footbed shape. The unique combination of layers allows the Birkenstock footbed to adapt to the wearers feet overtime increasing comfort with wear.

Each pair of Birkenstock sandals is truly one of a kind and individualized to its wearer. 

Open Toes

The majority of Birkenstock feature open toe designs. Having an open toe box allows proper room for your toes to move, adequate space for the Birkenstock arches, and promote ideal weight transfer.   

Natural Position

The bottom of each Birkenstock features flat soles. This creates proper weight transfer by dissipating pressure throughout the entire sole of the foot.

Buckle and Strap

Each Birkenstock is secured with a high quality strap and buckle. The ability to adjust and tighten insures that your Birkenstock fit snuggly and firmly. 

Additionally, each buckle is given a anti-corrosion treatment so you can rest easy that it will last for years of use.  

 

Natural Materials

Cork

Integral to each Birkenstock is the natural raw cork. This sustainable material provides unmatched elasticity, shock absorption, and heat insulation. Cork is a naturally reproducing product and each tree can be harvested multiple times without harming or killing the tree. 

The cork is harvested by peeling five centimeters of thick bark from a Cork Oak Tree. This process can repeated every seven to nine years, with each tree producing approximately 100 to 200 kilograms of cork during its life.  

Once harvested the cork is cooked thoroughly to ensure it is hygienic and clean.

Latex

Unconventionally Birkenstock uses a natural latex as its primary binding agent. Like cork natural latex is a renewable resource sourced from the resin of rubber trees. 

The harvesting process involves the extraction and collection of latex milk from matured (six year old) rubber trees. Each year ,for up to 25 years, 80 grams of latex can be harvested.  

Utilizing natural latex avoids the need for crude oil based synthetic latex. Further, natural latex is free from pollutants such as solvents or CFC, provides better energy balance, and has a higher elasticity-point. 

Birkenstocks Leather

In addition to cork, latex, and jute Birkenstock also utilizes genuine leather. As leather is one of the most robust and naturally durable materials it perfectly complements the build quality of Birkenstocks footbeds.
