Birkenstock Shoes & Sandals

The Footbed That Became the Shoe

Looking for footwear that feels different because the shape underneath your foot is doing more than simply cushioning it? Birkenstock builds its classic footwear around an anatomically shaped footbed designed to support the natural shape and movement of the foot. The original cork-latex construction includes a deep heel cup, arch supports, a toe grip, and a raised edge around the toes, creating the distinctive underfoot shape that has become synonymous with Birkenstock.

A Footwear Idea That Started With the Foot

Birkenstock's history goes back more than two centuries, with the Birkenstock family documented as shoemakers in Germany as early as 1774. The company's modern footwear philosophy took shape much later, when Konrad Birkenstock developed anatomically shaped insoles designed around the structure of the foot.

At the end of the 19th century, Konrad Birkenstock developed a flexible cork-latex footbed as an alternative to the rigid insoles that were common at the time. The idea was fundamentally different: rather than forcing the foot onto a flat or rigid surface, the footbed was shaped to correspond with the contours of the foot.

That footbed became the foundation for the brand's footwear and eventually helped establish the word “footbed” in the way we use it today. Birkenstock continued developing footwear around that foundation, expanding from its original footbed concept into sandals, clogs, shoes, boots, and other styles.

Why shop Birkenstock from Abbadabba's?

  • The Original Footbed: The anatomically shaped footbed remains the central idea behind Birkenstock's classic footwear, with multiple areas designed to support the foot as it moves.
  • Different Ways to Wear the Footbed: Birkenstock applies its footbed concept across sandals, clogs, closed-toe footwear, and other styles, so you can find the construction in different silhouettes.
  • Multiple Width Options: Selected classic styles are offered in different widths, including regular/wide and medium/narrow options, allowing you to look beyond length when finding your fit.
  • Different Footbed Feel: Birkenstock offers both its original footbed and Soft Footbed versions. The Soft Footbed adds a permanently elastic latex cushion beneath the suede lining for additional cushioning from the first wear.
  • Materials That Change the Look: The same recognizable footbed concept can appear under different materials and finishes, from natural leather and suede to Birko-Flor and EVA constructions.

The Anatomy of a Birkenstock Footbed

The Anatomy of a Birkenstock Footbed

1. First layer of jute. The foundation of the footbed, stabilizing the natural cork and latex core above it.

2. Cork and latex footbed. The heart of every Birkenstock. Shock-absorbing and highly flexible, the cork and latex core supports the foot and relieves pressure across it. The natural materials insulate against heat and cold and keep a good foot climate.

3. Second layer of jute. Wrapped around the sides of the footbed, this layer increases flexibility and makes the footbed significantly more durable. The thick, absorbent jute also regulates moisture.

4. Suede lining. The suede absorbs moisture. That property of the high-quality top layer is what keeps the foot climate pleasant through a full day of wear.

The Birkenstock Difference

The interesting thing about Birkenstock is that the footbed isn't an insert added to a shoe after the design is finished. It is the starting point for the footwear. The shape of the footbed determines how the heel, arches, toes, and forefoot interact with the shoe, which is why the familiar Birkenstock profile looks and feels different from a conventional flat sandal.

That approach also explains why Birkenstock footwear can feel unusual when you first put it on. Instead of a completely flat surface under the foot, you encounter defined contours: a heel cup, arch supports, a toe grip, and raised edges. The shape you notice is the point.

Fit & Comfort Tips

Take Your Measured Size

Birkenstock uses European sizing, so check the conversion rather than assuming your US number carries across. Round up if you fall between sizes.

Choose Your Width

Narrow and regular are genuinely different lasts. Your foot should sit inside the raised rim of the footbed without spilling over it or leaving a wide gap either side. Width matters more here than length.

Expect a Break-In

The cork molds to your foot over one to two weeks. Start at an hour or two a day and build up. Socks help while the straps are still stiff.

Soft Footbed or Regular

The regular footbed gives firmer support and takes longer to mold. The soft footbed adds a foam layer and is comfortable from the first wear. Sensitive feet usually prefer the soft, and anyone needing firm arch support usually prefers the regular.
