Upper material: Oiled leather
Oiled leather is one of our favourite types of leather. Its oily waxed surface makes for a unique colour effect and develops a beautiful patina. The oily finish of our natural leather products results in colour variation, making each and every pair unique.
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.
Outsole: EVA
EVA (ethylene vinyl acetate) is a high-quality, very light, elastic material with extremely good cushioning. As a result, it smooths out slight irregularities in the floor and ensures that every step is softly cushioned.
The Original Birkenstock Footbed
A legendary design
At the heart of every Birkenstock design is the legendary footbed. The details are all in the design; each element of the footbed serves a purpose to encourage proper foot wellbeing and health. The result is signature style coupled with all day comfort.
Deep Heel Cup
The deep heel cup cradles the heel and keeps your natural cushioning right under the heel bone.
Longitudinal Arch Support
The longitudinal arch support runs along the sides of the footbed, providing stability with each step.
Transverse Arch Support
The transverse arch support runs through the middle of the footbed, helping ensure proper alignment and a solid stance.
Raised Toe Bar
The raised toe bar encourages the natural gripping motion of your feet, exercises the legs, and stimulates circulation.
More Toe Room
A roomy toe box allows toes to move more naturally, promoting better balance and correct foot alignment.

FITTING AND ADJUSTING TIPS
SIZING
How to measure your foot length
- Stand with the heel to a wall and put a measuring tape under your feet
- Read off the measured foot length in millimeters before your longest toe
- If you are between two sizes, choose the next higher, because feet are minimally greater under load
Birkenstock products are offered in European sizes. Please reference our Size and Width conversion charts below. You can determine your Birkenstock size by adding 31 to your U.S. women’s size and 33 to your U.S. men’s size.
Your feet should be able to move freely without your toes hitting the edge of the footbed.

ADJUSTING
Before trying them on, put one hand under the toe and one under the heel, then flex the footbed a few times. This will initiate the break in period and will help your new sandals feel comfy sooner.
Open all straps and step into the footbed. Close the straps comfortably, leaving enough space to allow your feet the freedom of movement. Exhale and enjoy.
WEARING
For the first five or six times you wear your new footwear, limit the time to just a few hours. This allows your feet and body to gradually get used to the contoured arch support as well as the straps and buckles.
