Very simple, i think that Adidas started to make more pairs to increase revenue. They just made TOO many pairs/models and saturated demand. It started 5/17 with that R2 release.
Always wondering if anyone has done any trade anymore now that StockX/Goat makes it easy to sell and buy what you like. I have NEVER done any trades lol. just thought it'd be too much of a hassle to trade.
