So they over-allocated the stock they sold to resellers and are struggling to procure more in order to not get called out/sued for false advertisement.
They pulled the bait and switch on the original email as it originally said that pairs would ship immediately upon paying the invoice and then changed it up on the following email to that they would ship 8-14 days after. There are still local pairs that haven't even shipped yet, so I don't trust that I'll actually get them until they ship.
In hindsight, they really should have just delayed the 2nd half of the drop until they got shyt figured out instead of opening it back up and making things worse. A lot of these boutiques just don't have the resources or infrastructure in place to handle these type of mass drops and what comes along with it.
