How I Coloured in my Rubber Soles | DIY shoes transformation

After my first, failed attempt at completely upcycling my very worn-out and old shoes so that they could be worn once more, I decided to try again; so here's my second attempt at redoing the soles part that I deem successful!
I'll definitely (finally) be able to wear them again, which I'm very glad about :)
My first attempt that was partly successful:

As the title says, this is the way I did it but it's not necessarily the way TO DO IT in general. This isn't a tutorial , I'm just sharing my experience and a solution that works for me! I know that there are more effective ways to do this, and even more aesthetically pleasing ways to do this (like using leather paint I think or even car paint) but these shoes are pretty ruined as they are and honestly I'm just here to have fun. If it isn't fun, then why are you doing it for?
Money?
Understandable. Have a good day :)
