I have 2 pairs of the same shoes in the same colorway(least expensive). I need a good way to tell them apart, and the upper is black. Is it possible to dye the sides of the EVA midsole foam without damaging it in some way?
So far, I've considered thick markers to just scribble until it's a solid color, but I feel like that would end up looking pretty bad.
I'm out of ideas.
Thanks!
