Have been doing some research about how to make your shoe soles black, wondering if anyone has any experience with painting or dying their soles and how it worked after a few sessions?
I work in fashion and we dye a lot of stuff. We've recently been dying the soles of our sneakers in a wool (protein) dye before we give them to the shoemaker for construction. We've done blue and black and we're just using commercially available dyes, something like rit equivalent probably.
The dye doesn't really penetrate the rubber very deep, so after wearing the shoes, the original color of the soles starts to show, in our case, white.
You could also try edge dressing and kinda paint the soles, but I think it will be messy and it'll look fucked up in the end.
If you do any experiments I'd be interested to hear the results.
