“people argue that they’re too common and their quality is bad”
You answered your own question.
The quality isn’t any worse than other GR Dunks and the fact that they are common doesn’t bother me. The shoe is fine for what it is.
Pandas were THE shoe for a while until they got popular/common. Now they’re similar to people that gatekeep bands by saying things like, “Yeah, well I was listening to them before they were cool.”
I don’t doubt that you’re right but why would anyone enter their payment information into what are obviously fake sites?
