I think it actually goes both ways. They might have been initially incredibly popular and subsequently Nike flooded the market with the sneaker to the point that it ended up on clearance shelves (https://solecollector.com/news/2017/04/air-jordan-1-og-sales...).
The article also mentions that Nike targeted ~3-4 million pairs of the sneaker, which is relatively high for a hyped sneaker.
For a modern comparison, this article (https://thesolesupplier.co.uk/news/heres-stock-numbers-off-w...) claims only ~48k pairs of last year's hyped Off-White x Nike Blazer Mid ‘Black’ sneaker were released.
