Tennis Zone International, Former ATP World No. 52 Player

“I am very positively surprised by the small gadget and would not have thought that it would work so well. It’s very easy to use, just peel off the protective film, stick it in the shoe, put it on and you’re done. Especially after long and exhausting days, when I played a lot and was in action, I noticed an extreme regeneration effect of the Powerinsole. Since then, I enjoy much more fitness the next day than I did before!”
