Nike Metcon 7 Women's Trainers have a lighter and more breathable upper than the previous version to satisfy our standards of durability and comfort. They will allow you to do cardio, give your all during weightlifting and master your workouts. Nike React foam offers a soft and reactive tread and a comfortable base that's cushioned, lightweight and elastic for cardio and sprint exercises. The grip rubber wraps around the bridge of the foot for the most intense rope climbing sessions.
