The spiky sandals are an evolution of the original Berkemann sandals. However, the spiky material ensures a boost of blood circulation on the soles of the feet, as the pimples massage the base of the foot with each step. With the original sandals, Berkemann has a real classic - or not the forecursor of all today's active shoes. In the 60s of Prof Dr W. Thomsen for Berkemann originally developed as an instrument for prophylaxy against misalignment of the feet in children, original sandals conquered everyone (adults). Today, nothing has changed to the principle of muscle training and muscle building when wearing original sandals. Step by step, the leather changing strap and the wooden sole act according to the leverage principle and thus train the muscles of the foot and calf. In addition, the 5-phase footbed integrated into the wooden sole supports the natural unrolling of the foot, whose toes grip function is in turn, activating the muscle contraction in the foot and calf. So you can see the original sandals as the smallest gym in the world – you can even take it anywhere.
