not really sure if a high or mid is in the mix too, there hasn't been much info yet. judging by the way that collar looks to be more of a bootie like the liilards, i would venture to guess no, they were meant to be like this, but that's just my opinion. also, heel boost only seems like a pass for me, even though it looks super thick and plush on this model. there's a closer look at them on weartersters if you're interested.
The forefoot part is encapsulated so maybe that is why there isn't the same bounce? The probably designed it that way too because it is a bball shoe and they may want to give it a closer to the court feel?
UltraBoosts are also the newer boost sole that has more of those foam stuffed in there.
