Best Way to Dye These Shoes?

[misterpunn]

I am interested in buying these from FNL and dying the neon parts so the upper becomes all black. I've painted shoes but never dyed fabric on shoes before. What is the best way to go about doing this?

I've provided the link below so you can look at the product photo and zoom in to see the exact material but it seems to be some sort of nylon. Any help is appreciated!
