While Xeno might be the dopest tech now in terms of upper, Adidas Chromatech might be inching very close. As you can see from the images here, it looks like a Xeno upper which in case you don't know changes color when light hits the material. So hues of colors might be produced when light hits from different angles. Going back to the Chromatech, the upper material changes color when it stretches or constricts. The first time I read about this, it was on the SL Loop. So with this tech being utilized in the Superstar silhouette gives it another depth. Who knows, we might even see them on other models as well. These are available now in stores like Oneness, so if you want one, you can go to their site by clicking <HERE>.
