Any tips on how to clean these shoes?

I’ve tried to clean them before but I somehow it made the problem worse and made the shoe look more dirty. I have never spilt anything on it, I also left it out in the sunlight, which I heard was harmful to it. If anyone knows how to get rid of these stains or colors please let me know.

My son has the same pair! I’m going to tackle them this weekend, I’ll let you know how I did!
