Ahhh hi there~! I’m so sorry for the late answer! D’:
The thing is: I already had the shoes at home. They‘re a few years old already, so you probably won’t find them in the stores anymore… Also, they’re real leather so they might be a bit expensive if you buy them new….
The brand’s name is Zanon & Zago if you want to try searching online!
As for the paint, my shoes were already grey from the beginning…. If you want to paint your shoes, there’s car interior paint or Angelus leather paint which I’d recommend. Normal spray paint might not dry well and stay very sticky. Acrylic paint out of the tube could peel off of the smooth surface.
In my opinion, it’d be better to sew a shoe cover rather than painting your shoes. :)
Here’s a nice tutorial by mechafaux.
I wish you good luck!!!! Feel free to ask if you have any more questions~ <3
