I too, am choked there has been NOTHING about 98s releasing this year.
The market is saturated with junk colourways of the 97s and they keep releasing more.
Dunks, 97's, Uptempo 96's ... pumping out tons of colours. The market is saturated. There is no way people are buying this many 97s and Uptempo 96s. Not even a sneak peek of a 98 for later this year yet.
@ 1:41 you can clearly see the air unit found in the old Uptempo shoes. The heel air unit in the 19's seems to be an upgraded version but largely the same shape and principle.
The underside view of these shows what it looks like. It appears just to be an updated version of the air unit that's in heel of many of the Uptempo shoes. A 'U' shaped air chamber with a smaller 'U' shaped line of foam separating an oval air unit in the middle.
