From anecdotal evidence, I've got the same pair of sneakers for... 4 years now I think? I'm using them daily and yeah, they've got dirty on the bottom, but I wouldn't consider throwing them out just due to that. I'll replace them once the sole is damaged to the point the shoes stop performing their function. At that point, it doesn't make a difference whether it's white or black for the sole. You could have made your point two replies earlier and it would be more clear what you consider the issue with white rubber to be.
