Chewing gum out of deep tread of shoes

[lljkk]

Apologies for the dull dull dull Saturday morning topic.

I have some nice Clarks doodles I want to flog on Ebay, problem is they have small residue amounts of chewing gum ingrained on the tread.

I could freeze, but amounts are so small, will it harden up & be easy to pry out?

I could WD40 or use acetone, but that would leave a stink wouldn't it? I want to sell them ASAP.

I will try freezing, any other ideas welcome.

I'd have thought freezing would help it contract a little, so make it easier to come out?

'sticky stuff remover' spray from Homebase etc? Imagine it's the same as WD40 bit not as strong smelling.

Egg white - tried it on a skirt and it sort of dissolves the gum and then I guess you coud put the Doodles in the washing machine?

Thanks for suggestions, some too expensive to try, sadly (the shoes aren't that nice!).
WD40 was okay, actually, doesn't smell worse than actual plimsol smell, anyway, and helped me remove some more. I am listing them on Ebay with a note that they have tiniest amount of chewing gum residue left (huge blow up pic so buyers can see for themselves), I'd have to destroy the tread to get it all out.
