Sports scientist & ultra trail runner

After initial skepticism regarding both its effectiveness and the fit in the shoe, I'm now a firm believer in the Powerinsole! I especially notice the effect after long training sessions and/or competitions. I recover faster and can therefore train more efficiently. This is also reflected in my training and competition data. I'm currently recovering from a torn lateral ankle ligament. The typical bleeding quickly disappeared with the Powerinsole (increased blood flow). It's simply wonderful when the promised effect actually occurs amidst the maze of "biohacking/self-optimization" tools!

Therefore: Whether during sports or in everyday life – the Powerinsole is in my shoe!
