Good suggestion. I'll see if I can find something for that. Just put zagg shields on the soles this evening. I bought the kind without the spray solution and they seemed like glued on... Bit worried if I ever try to remove them they may pull the paint off but hopefully I never have to remove them if I'm careful.I recently glittered a pair of CLs myself and used an acrylic sealer that seems to have helped keep everything in place. You might want to try a little bit just on the heel first, I think it comes in different finishes so you’ll want to find one that doesn’t change the look.
