Primeknit takes the ZX Flux line as well. Even with just the regular materials, the silhouette itself looks slim to the foot and now with the upper being made from Primeknit, not only does it look slimmer but it gives you a sock-like fit. The 3 stripes branding on the sides were made from a fuse material so it would not mess with the soft feel that Primeknit gives. There is a suede heel counter to provide more structure and torsion bar below for support underneath. Three colors are available now and retails for $130 at Adidas <HERE>.
