Note with the spier verse origin AJ1s they have an icy sole which looks nice when Brand new but as soon as u wear them a few times they dirty and yellow easy. Unless you like the look of a brown yellow sole, you all be cleaning a lot. They oxidise quicker than normal soles so eventually the yellow will be permanent unless you do the salon 40 creme in UV light thing but that's long to do often and not sure how effective. At least this is what I've seen from FB groups I'm part of. Maybe others have different experience.
That's good to know, thanks!
