Rob-L custom - Nike Air Max Light "Speckled-Jade"
Here's the base shoe:
The permanent masking medium is some sort of latex solution which is designed to be painted with, so it mixes into the paint well. Took a while to dry and stop being sticky, but it seems pretty solid and flexible. A wear-test is the only real way to know, but it feels pretty well adhered to the midsole.
I then masked them up and speckled them with various spray paints...
