Nike designed the Free Trainer 3.0 V4 to perform its best in the most intense of workouts with an all-new upper that has been designed from the ground up to focus on mobility and dynamic support. The shoe's upper was designed to move and react with a circular knit material that locks the foot in place, reducing friction while you're on the move.
Light and low to the ground, the shoe is designed to move quickly in all directions as the fiber expands and strengthens as you move while also creating a stable and secure platform during your workout. The upper is matched with their Free 3.0 sole that features six different flex points for the foot to move in a much more natural way.
The Free Trainer 3.0 V4 will be available at nike.com on July 8th.
