Oh ok I kind of figured that but wasn't sure.
The problem with that argument is that you state that people don't care and probably don't know that kanye makes shoes... Then if they don't care then why would they even be considering buying replicas of said shoe. Wouldn't they just keep it moving and walk into one of the huge chain stores present at every mall and buy something in stock. Wouldn't that be the majority of the demographic you are referring to? While the minority in that group would be the ones that care enough about it and decide to investigate where they can get them. Then an even smaller portion of that same group would have to make the decision to go the replica route and risk being scammed by having to pay via unsecured methods (WU, MG, etc.)....
If your're claiming that sneakers enthusiasts and collectors are simply a niche group that only represents a small fraction of the overall sportswear consumer demographic... then you are absolutely correct... but then at the same time you have to realize that people that actually care enough to go a research and purchase the top of the line replica in existence is as small or is not smaller than the sneaker enthusiast and collector community.
But yes overall the replica market is growing. It's just that the argument you were making to support it is not logically sound.
