Back in the day Nike invented cross-training to meet the performance needs of two-sport athletic phenom Bo Jackson. 25 years later, Nike unveils the latest progression in the evolution of state-of-the-art training footwear, the Nike Lunar TR1. Built for the next generation of world-class athletes — like decathlon world record-holder Ashton Eaton — the shoe is the lightest Nike Lunar Trainer training shoe yet, featuring breathable, lightweight mesh integrated with dynamic Nike Flywire. The TR1 is engineered to get the athlete lower to the ground — good for added stability and traction — while Lunarlon cushioning accommodates a natural range of motion, enabling longer and harder workouts. The Nike Lunar TR1 is available now in stores and at Nike.com.
