Not sure if it helps, but when I did my Lenalee boots (had a glowy-blue detail on them), I went and bought adhesive fishing lure stuff (not sure what the specific name is). It came in sheets so I could cut out what strips or pattern I needed and then stick them to the boots. It layed well on them and stuck great long term.
