I have a leather sneaker which I've put outside of my house for months. Then yesterday when I finally decided to wear it once more, I've noticed that the navy blue-dyed leather has somehow faded. At first I thought it's just dust and wiped the leather surface with wet wipes, but after the failed attempt, then I came to confirm that the leather has indeed faded.

Any ways to restore the leather sneakers?

inb4 TS lacks leather maintenance xp and still wanna buy dyed leather sneakers
