Hi there, I've seen quite a few tutorials about sneaker-customizing and prior to trying it out myself I'd like to get some advices from you guys beforehand. So, I got these Lebrons a while ago and I pretty much like the shape and fit but the color bothers me. So far I've replaced the neon-green laces with black ones, changed the color of the pull tabs from pink to black and got rid of the bigass Nike-Swoosh that was glued onto the mesh. What I want to do now is to recolor the shank from silver to plain black. Just the silver part, nothing else. Most Tutorials recommend Angelus for customizing sneakers but the part I want to deal with isn't leather but rather plastic or some kind of rigid rubber.
