While I agree that they are over saturating the market to a certain degree I definitely did not see these having ANY issues selling out. EVERY color/model of Yeezys (with the exception of the 950 Boot) have sold out without an issue. Although this past release put stock numbers somewhere in the 60k mark that is NOWHERE near a general release Jordan model (250k+ pairs). Jordan brand has a ton of issues that are contributing to their products not "selling out". Yeezys at this time are in the demand>supply bubble. Word is that they ran into some production issues whether that's true or not is anyone's guess as Adidas hasn't made any official announcements yet.
