Pointed high heel shoes

Yesterday I had our Unda Maris studio rehearsal where one lady beginner organist came to try out her shoes for organ playing.  Her name is Diana and she is playing a trio No. 1 by Lemmens.

These weren't regular organ shoes but the shoes from her collection that she sometimes uses for violin recitals on stage.

​They had pointed toes and high heels. I don't usually have a problem with high heels but this time they were narrow. We tried to put them against the pedals and it appeared it would be easy to slip between the keys.

Also their pointed toes would mean that if she placed her toes on the edge of the sharps as we should do, the real end of the shoes would come somewhere in the middle of the sharp key.

I told her to try out and see if this seems comfortable or not. I said that it would take maybe 5 times the energy to hit the right pedals with this kind of shoes.

Of course, we all know the stories about female virtuoso organists who play with high heels but this is really advanced level.

What do you think? Should she keep trying to adjust to the difficulty of playing with these high heels and pointed toes or should she just get a pair of real organ shoes?
