The Nike Killshot OG SP QS CU9180-101 Sail/ Gym Red is an original tennis sneaker. Featuring 1-to-1 retro highlights that return to the OG look, with a variety of throwback materials. The upper combines layers of open mesh, with visible foam underneath and soft suede overlays. The lateral Swoosh and "NIKE" design on the heel tab feature crisp leather, adding a finishing touch to the richly textured silhouette. The exposed open foam tongue adds a DIY touch with classic styling. Heritage sole brings a court-side attitude while the super plush foam insole and the padded low-cut collar keeps it sleek and comfortable.
