Dora Huguenin, museum tour guide in Le Locle, Switzerland

I had a problem with heel spurs. I couldn't walk any more. The doctor told me to walk for at most 20–30 minutes a day; no more walking uphill or downhill. And by coincidence I was in Bern and passed a kybun shop. So I went in and came out with a pair of kybun shoes. I put the shoes on straight away. They advise you not to wear the shoes too much at the start, but I've been wearing them since day one, and haven't had any problems in any of that time.
