His 19th signature gives you the feeling of containment but with a lower, lighter design that's ideal for fast, strong players like LeBron who stretch the court. Power Under Pressure A thick, visible Max Air unit cushions your heel when it strikes the floor. Harnessed Energy Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. It's exposed along the sides and caged in front with a sculpted TPU overlay. Light and Strong Translucent woven material in the upper is durable yet lightweight. An overlay across the toes provides forefoot stability. Foam pods on the collar provide ankle support. Rubber outsole gives you multidirectional traction.
