Berkemann Original sandal - 12536

With the original sandal, Berkemann offers a true classic, if not the predecessor of all modern active shoes. Developed in the 1960s by Prof. Dr. W. Thomsen as a prophylactic tool against foot deformities in children, the original sandal quickly conquered the entire adult world within a few years. The principle of muscle training and strengthening while wearing the original sandal has remained unchanged to this day. Step by step, the leather strap and wooden sole work according to the lever principle, training the foot and calf muscles. The integrated 5-phase footbed in the wooden sole supports the natural rolling motion of the foot, culminating in the toe grip function, which activates muscle contraction in the foot and calf. Thus, the original sandal can also be seen as the smallest fitness studio in the world that you can take with you anywhere.
