Regardless of whether your pace is snail-like or lickety-split, the Nike Metcon 8 AMP helps keep you on the go. Expressive, playful graphics remind your fun can be found in every workout, no matter how tough. The upper is lighter and more breathable than our previous edition to complement our standards of durability and comfort, so that you can float through your cardio and power through your lifts. Spring in Your Step Delivering a smooth, responsive ride, Nike React foam makes a comfortable, cushioned base that feels lightweight and springy when you kick into high gear for cardio and sprints. Grip from All Angles Grippy rubber wraps around your arch during intense rope climbs. Rubber tread gives you traction and helps you stay on your feet when transitioning from the training room floor to the pavement. Stability for Lifts The wide, flat heel gets even more stable with an inner plate that distributes weight from edge to edge. It also flexes to make it comfortable for cardio and sprints.
