Kevin Durant is on the court every day, going hard and getting better. The KD Trey 5 IX is built to keep up with his furious work ethic. It gives him the sensation of cloud-like cushioning and broken-in comfort he likes, so he stays fresh and focused. Smooth Energy Return Nike Renew technology combines a soft inner core of foam surrounded by a firmer foam for springy and resilient cushioning. A Zoom Air unit absorbs force and returns energy with every step. Lightweight Mesh Lightweight, layered mesh in the upper creates a secure, supportive fit. It's structured and reinforced where it's needed most. Sound-Wave Traction The rubber outsole with a sound wave-inspired traction pattern helps you grip the court in multiple directions. The pattern is a nod to KD's love of music.
