Earlier quoted context omitted.
Can you elaborate what you consider the problem to be?
Seriously? It's white, optimized for showing dirt. It's closest to the ground, optimized for getting dirty. And (In the case of your typical sneaker) It's a special weird porous rubber that is difficult to get clean, optimized for quickly looking like crap. And when your shoes look like crap it's time to buy new shoes. Thus we have shoes optimized for short lifespan. But this is dead obvious.
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.
