Original Single Firm
One of our most popular models: Formthotics Original Single Firm, made of single-layer Formax foam, are full-length and offer reliable control and stability in the proven Formthotics Original shape. The standard shape with arch support and a high heel cup provides firm support in all shoes. Thanks to their discreet colour, the insoles don't stand out in elegant footwear. They are lightweight and extremely durable, even with daily use.

Why do feet need support?
You might think that, after thousands of years, humans would have perfected walking upright by now. So why do so many of us need medical insoles to support our feet and give them stability?

Our feet were made for soft ground. However, for around 200 years we have mainly walked and run on hard asphalt, stone, wood or concrete floors, and our feet are forced to flatten and twist with every step.

Many shoes don't support the feet. High heels, narrow toes, shoes that offer no support or don't fit properly cause unnecessary discomfort. The insoles in cheap shoes are flat and provide no meaningful support for our feet.
