Hi @pollux.one, Your wife seems professional or she just like the idea:

How someone can come to the idea to fix two blades to ones feet and then move VERY FAST on quite hard ice is totally beyond me. My wife loves it and quickly gets red cheeks.

This is frightening:

Nowadays you go to a hall because it it less dangerous and because you can't drown. But the first warning you get entering such a hall is, to be careful of your hands and keep them close to your body if you fall down, else you can loose fingers. => very much a trustbuilding concept.

But I'm still going to give it a try in coming summers. Thumbs up!
