Manuela Fellner, singer and Swiss Grand Prix champion, Switzerland

I'm happy when I can change my shoes. I had to strut around in high heels on the gravel, and on top of that I had stones in my shoes. I'm glad I can put my kyBoot shoes back on.

I told my colleagues in the Netherlands too, but I don't know where you can get the kyBoot in the Netherlands. If I knew it, I'd tell everyone to go there. And my colleagues here in Switzerland are very keen. One of my colleagues has a daughter who wears the shoes; she works in them in Biel. And the director says the shoes might be his kind of thing, too ... So it's being passed on!

I had always wanted to experience the feeling of walking on air. I also hope that I’ll get to experience the feeling of sleeping on air sometime, too. I was fascinated by this shoe; I wanted to try it on right away. I thought to myself: I’ll test it out now. I stuck with it – it’s been nearly eight years now.
