With the original sandal, berkemann has a real classic in its range, if not the forerunner of all of today's active shoes. In the 60s by prof. Dr. Originally developed by w. Thomsen for berkemann as a prophylactic against foot deformities in children, the original sandal conquered the whole adult world within a few years. To this day, nothing has changed about the principle of muscle training and muscle strengthening when wearing the original sandal. Step by step, the leather strap and the wooden sole work according to the lever principle and thus train the foot and calf muscles. The 5 phase footbed integrated into the wooden sole supports the natural rolling motion of the foot, at the end of which there is the toe grip function, which in turn activates muscle contraction in the foot and calf. So you can also see the original sandal as the smallest fitness studio in the world which you can even take with you everywhere.
