If we're talking about Fashion, which I think we are, the main thing that distinguishes cheap shoes from expensive shoes is a name.
No. There are some very, very obvious symptoms of a cheap shoe that were clearly missed at "Palessi." Glued soles, cheap plastic, pleather, cheap foam lining, etc. should all jump out to anyone at first glance.
I agree that the people who were invited to Palessi were not who the company was trying to convince to by Payless shoes, and in that sense, it's clever marketing. But any of us should be able to tell the difference between Payless quality and higher end fashion if you're looking at it/holding it in person. It's easy to get so caught up in the hype of the invite and the look of the pop-up store that you don't scrutinize the product; but there's zero chance if anyone of those people spent 5 minutes with their $600 payless shoes outside of the store that they wouldn't realize they bought an inferior product.
