Best way to paint shoe soles???

I have these slip resistant shoes that I'm going to use for the base of my boot covers but I need the soles to be a different color. (I got these in black since that was the only color available and also I needed something slip-resistant since where I live is covered in ice half of the year).

I was thinking of priming and spray painting them but I've done that in the past with different shoes only to have them turn out sticky and they never fully dried. Would painting them by hand be better? Or maybe I didn't do it right.

Also it would be great if I could get the paint to stay instead of peel or flake off. But if there's no way to do that then I'll just reapply paint when needed. No biggie.
