Tennis Coach Hannes Pühringer
I have been using the Powerinsole for about 2 years, and I am very satisfied. As a tennis coach, there are days when you spend 8-10 hours on the court. During the last hours and afterwards, you often experience heavy legs. A friend gave me the Powerinsole back then, and I was very skeptical at the beginning. What could these 2 patches in the shoe really do? But I noticed an improvement already on the first day. No more heavy legs. And the recovery time is significantly shortened. Since then, the Powerinsole has always been with me.
