Hello ! Thank you so much for picking my question, sorry, I wasn't very specific, loved the answer :)
For your red shoes, all I can say is : try to get a pair that won't hurt your feet ? It's always when you're looking for something specific that you're finding it...
I'm glad your laptop is working ! Yes reinstalling is a big thing, you have to save all your work elsewhere... In my opinion, if it works, better not do it.
