what's your best method to remove glue from a shoe outsole?
I had to attach a piece of plastic 1 inch thick to a shoe sole to make it 1 inch taller. Why is not relevant.
After using this frankenshoe for 2 months I no longer need it, but the shoe sole is sticky.
I used isopropyl alcohol to rub it and removed a bit of junk, but part of the surface is still sticky. I applied more isopropyl and let it act for an hour. Still sticky.
Hey friend I'm a cobbler that does those kind of lifts all the time. I use a contact cement that is removed with acetone but acetone along with isopropyl alcohol can melt the material that some soles are made from so be careful. Aside from that practicing your moonwalk on the pavement outside with them on will help plenty with the stickiness if it's just the adhesive on there that's the problem
Search for "Hexamethyldisiloxane adhesive remover". It's designed for removing ostomy bags but it will remove pretty much any gummy sticky glue from anything with very little effort.
