^i used the magic eraser on the painted areas of both my mocha's and white cement's when i got them. my general rule of thumb is use shoe cleaner firstto see if it removes all marks and stains. if the marks are still there, then time to use the magic eraser. just got to rub over the painted area (assuming themidsoles is what you're talking about) and it will take it away. amazing what a little sponge can do for you for $3.00. now if i could only get a whitecastle on the west coast!
^^shoe cleaner, if not, then mr clean magic eraser. these items won't make the shoes yellow.
^^^ i wish you had some pics to see how bad those bordeaux's are. the scuff mark could possibly be fixed with a suede/nubuck eraser, but i wouldn't doit cuz of the age of the shoe. it might just tear it up. as far as the sole separation, use either shoe goo, epoxy glue, etc. can't recommend gorilla gluejust cuz how it hardens when it dries. so it would just crack on you when you try to rock them bad boys if you know what i mean. also, if the scuff is startingto become chipping on the materials, then there's really no way to fix this.
^^^^ i've never seen a sole swap on vii's. can you imagine how much time and effort it would take for this? unless it's for a pair ofbordeaux's or og hares, i would just stay away from doing that much of a project.
