Sports Scientist & Ultra-Trail Runner


After initial skepticism regarding both the effect and “fitting” in the shoe, I am convinced about the Powerinsole! I especially feel the effect after long training sessions and/or competitions. I regenerate faster and can therefore train more efficiently. This is also reflected in my training and competition data. I am currently recovering from a torn outer ligament in my ankle joint. The typical bleedings have disappeared in no time with the Powerinsole (increase of blood circulation). It’s simply wonderful to feel the promised effect actually occur with one of the many “biohacking/self-optimization” tools out there! Therefore: no matter whether during sports or in everyday life, the Powerinsole is in my shoe!
