The peeps in here talking prices about these and kaws should include the size you referring to. Kaws black in a size 9 never dipped below 900. Now they're at 1400. I do see prices dipping slowly across the board for all sizes in TS6's, but no one knows why for sure. Maybe 6's just have less desirability compared to 1's (that's a fact) or maybe it's because fakes are getting through. It's definitely not some guy/group buying up the stock because if that's the case, then they'd be accepting the lowest asks each time, which would drive up the price vs the bids/prices consistently dropping.
The way I see shoes is that the earlier you can get in your pair on the market, the better. Too many rep factories correct initial flaws and there's no telling if you have a fake on the resell market with time. GOAT and stockx aren't 100% authentic at times so better to just get it over with right away. Maybe I'm just trying to justify overpaying for my TS6 now lol, but there's definitely ways to LC these at the moment (i.e., soles showing up as blue vs green in blacklight, jordan logo, etc.). I'm sure those will be corrected with time.
