While most people associate Birkenstock sandals with the hippie movement of the sixties, there is much more to remember about these well-designed shoes. Though they are made from natural materials and are crafted to last a long time, these are not just qualities that "flower children" can appreciate. In fact, Birkenstocks have been around a lot longer than the hippie movement ever was. Here's what you need to know.

Back in 1774, Johann Adam Birkenstock was registered as a shoemaker in a small German town. While this seems to be the beginning of the Birkenstock name, the actual sandal itself would not emerge for a few generations. In 1897, Johann's grandson Konrad began to look at shoe design in a completely different way than other shoemakers of the time. Though the typical shoe was made to be flat, Konrad noted that our feet were rounded, so perhaps this flat shape was not an ideal design for comfort.

A few years later, Konrad designs an arched insert that can be put into shoes in order to cushion the foot in that typical flat design. This helped to create a more comfortable walking experience, while also helping to establish the Birkenstock name.

When Carl Birkenstock became involved in the business in 1925, these inserts where then shipped to Europe and command a high level of popularity among all social groups. As the popularity grew, medical community itself began to sing the praises of this new shoe design.

In 1964, the inserts become the base for the design of the Birkenstock sandal in Germany. These sandals become extremely popular as well, even showing up in spas and health centers.

Birkenstocks supported the tired feet of Californian Margot Fraser at a spa in Germany, and from this single experience an importing business was born. Birkenstocks, during this time, are being sold from an importer in San Rafael, California and word is spreading throughout the country.

The contoured insole of Birkenstock sandals and shoes are the selling points of the company. Over time, the foot of the wearer creates a custom fit in their Birkenstock shoes, making it a unique comfort experience with each step. And with a number of designs and materials, you can now customize your Birkenstock experience beyond the typical two strap sandal.

Currently, sandals, clogs, and shoes for both men and women, in addition to children can all be found at local shoe stores. Sandals come in a number of colors, and are available in leather, manmade leathers, and other materials. You can also find recycled Birkenstocks as well as those made from suede.

The number of straps varies from style to style and they also now have straps to secure the foot in the back to prevent slippage. There are also three different types of Birkenstock support systems now - professional, high arch, and soft bed. These help different wearers with their specific arch concerns and should be tried on before they are bought.

You can find a number of retail stores in the United States as well as many listings on auction sites and other online shoe sellers. Check out specialty stores in order to guarantee the authenticity of the shoes. When you go to a smaller store, you will also be able to try on a few different pairs to see what support you need and what look you want. Note that the Birkenstocks can be quite expensive, but they will last for decades without looking any worse for wear.

The company is employee owned and it shows. With great attention to customer satisfaction and comfort, innovations are plenty and customers keep coming back.
