Nike Free TR Flyknit 3 AMP Women's Training Shoe JUICED UP FOR YOUR TOUGHEST WORKOUT. Breathable Flyknit construction and dynamic Flywire cables make the Nike Free TR Flyknit 3 AMP Women's Training Shoe an ideal workout companion. A rounded toe plus aggressive siping on the outsole allows your foot to expand and move naturally while its flat heel optimizes stability.
Flyknit 2-piece upper provides breathability, stretch and support. Flywire cables function as eyestays for midfoot lockdown. Flex grooves allow the foot to move naturally. Flat heel creates a wider surface area for greater stability. Emphasizing a healthy lifestyle, each color in the AMP pack is inspired by common ingredients for juices and smoothies—green juice, carrot juice and almond milk. Each shoe features a marbled outsole which symbolizes the blending of different juices.
