From the BBC:
Tom Rayment said he was on the Adidas website for about two hours trying to get hold of a pair [of Yeezy Boost 360s] but was unsuccessful.
The self-confessed trainer fan, 24, from Peterborough said he already has four pair of Yeezys.
"When they were first released there wasn't the demand like today," he said. "I feel people just buy them to resell so they can make profit, then it is the genuine trainer lovers who pay the extortionate prices to the re-sellers."
My son used to have a bit of a trainer fetish (it's worn off now, thankfully). Apparently there are "real trainer fans" with thousands of subscribers to their YouTube videos showing off their latest purchases.
The gimmick is, you're not allowed to actually wear them. You keep them in the original box and only get them out to show your mates.
