You and everybody else. This is where the putty comes in.
Can you elaborate what you consider the problem to be?
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.

Thus we have shoes optimized for short lifespan.
But this is dead obvious.
