One of your best post ever. Bravo! I don't care too much for used shoes either. As to the OP's question, if I like it and I can afford it, I buy it. I'm generally fairly responsible in my spending with a few minor exceptions (some things you just have a passion for and your spending will often reveal what those are). I don't presume to speak for anyone else as to whether their spending is justifiable or even needs to be justified.
