goo gone! or any type of sticker shock will work great. fingernails. really up to you.
its a pain to get off no matter what you use. sticker shock helps, but dont expect a
miracle outta it. and a forwarning, this will happen with EVERY stomp pad that doesnt
naturally fall off because of crappy tape, so be prepared to do this every time you change
it.
but you're not looking at a big job no matter what.
thinking back, my 1st foam stomp pad was a ride logo, and it just had double sided
booger tape (very thin adhesive tape, like scotch, most stomps use a thick foam tape) and heat got MOST of that off. so you can try using a hair dryer and a dull knife
to pry it off in 1 strip if it is tape. if its glue, its more like a sticker and use the above
method.

just do not goo gone the bottom of your board!!!!!!!!!!!!!! if you get some on the bottom get
it off immediately.

i use heat for that crappy booger tape that most of the foam stomps use. usually comes
off in 1 pull..atleast most of it.
its that thick foam tape that sucks, like dakine uses, thats a real pain if its stuck good. my
god that stuff wont give up no matter what. its worse than the board stickers that the
manufacturer puts on. it took me 2 days to get that stuff off my grudge. and blisters!
