NB, Asics & runners/trainers, in general, will always have their niche market. There is a bit of excess clientele at the moment, but I actually like it as more collaborations are being pushed out allowing me to attain GRs for great prices as they went unnoticed. I don't see it reaching extreme levels as most collectors I know rarely invest in casual runners...
As for the UNDFTD orders, I'm not sure what's going on as I didn't order through them, but I know they went through a website overhaul recently. Might be taking time to sort things out or you may get a package well before getting actual tracking information...
For those able to get the Ball and Buck collaboration, I've been in contact with the owner over these past few days. Definitely a solid dude and orders should be shipped out today. There was an error for those that used PayPal regarding actual shipping costs so they had to adjust that over the weekend...
