The athlete’s natural-born movement is unleashed with the Nike Free Hyperfeel TR, the lightest men’s training shoe in history (6.5 ounces, men’s size 10) and designed for high-intensity training. By combining biomechnical research and innovative manufacturing, the Free Hyperfeel TR is the first Flyknit that combines three of the brand’s most revolutionary innovations: Flyknit, Lunarlon and Nike Free. The shoe’s lightweight upper acts like a second skin for the athlete’s foot, providing ultralight, training-specific support with a contoured fit. Flyknit technology seamlessly integrates areas of breathability, stretch and support where they’re needed most. The upper features dynamic Flywire. The shoe’s drop-in Lunarlon insole delivers soft, responsive cushioning. A thin web rubber outsole provides traction and durability for both indoor and outdoor wear, while retaining Free’s famous flexibility. The Nike Free Hyperfeel TR will be available at Nike and select retail locations beginning May 1.
