One of the unique features of the new Nike PG 4 is that the laces are not fully exposed. The model will feature a one-piece mesh upper along with a zipper which will expose the lacing. The medial side also exposes more of the tech underneath which it comes with a webbed lacing system. While not confirmed, the PG 4 is also expected to come with a full length Zoom Strobel which has been used on the KD 12. In addition we have a fuse overlay on the mid-foot which will help with containment. Lastly is a rubber outsole with translucent areas.
