It's not just the look because if Spalding made a shoe with the same exact design, they wouldn't cop. ...But, the thing is, you wouldn't either.
People cop because they get attached to brands and what brands stand for. Older generation purists (myself included) like to bash the youngins for the arbitrary nature of their desire for the shoe, but the truth is that we are pretty damn shallow ourselves as well. We are brand ****** too. Sure, over the years, you've developed a deeper relationship with brands and pieces, but when we got into what we got into, we didn't have any more lofty reasoning than today's kids do.
This is what the cool kids in my hood wear. This is what my favorite athlete or musician wears. Over time, you stuck with it and it played a part in the fabric of who you are and the subcultures with which you identify, but that happens over time.
Truth is, people like us are actually the outliers, not the norm. 15-20 years ago, all my friends were either dipped in, or aspiring to be dipped in the Jordans, Air Maxes, and Stadium Plates or Bear Knits, or whatever. Most people don't actually develop a true long-standing relationship with stuff they get into as teenagers though. I'm the only one of my friends who still has hundreds of sneakers, and storage bins full of the same gear we all obsessed over in 1994.
So, people like to play this card to clown the kids today -- and I do it too. But, the truth is we aren't nearly as above the fray as we think we are. And, they aren't as different from us at their age than we like to pretend they are.
