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 positioned under the ball of your foot absorbs force and returns energy with every step. Lightweight Mesh Lightweight, layered mesh on the upper feels secure and supportive. It's designed with structure and reinforcement where they're 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.
