SNKRS sg is like that. Despite being sold out, it will show in stock while processing orders in the back.
If you don’t get in for hype shoes within the first few seconds, it’s unlikely that you’ll get them.
I don't this colorway is being hyped...But even the Black Satin and Bloodline also can be sold out within minutes on SNKRS SG but still available at Footlocker till today at the same price...
