Earlier quoted context omitted.
I'm guessing the OP doesn't use their shoes for much more than walking around indoors. On the other hand when I skateboarded to work I'd go through a pair of shoes about every 3 months (that's what happens when your brake is your shoe). It was still cheaper than gas and faster than public transit though.
I had a pair of Converse that I used for this purpose. Completely torn to shreds and full of holes. Had an Asian lady stay at our Airbnb and she saw them, said people would go crazy for that "distressed" look in Asia (forget the specific country) so I gave them to her for her to take back.
I was on the train with my girlfriend (att) and she deliberately stamped on my foot. Of course, I was quite confused; however, she explained that my shoes looked too new and thus needed to be dirtied up a bit.
