Pay homage to a hero, an inspiration, a guiding light who helped you along the way in this special Nike Metcon 7 AMP. With room to inscribe a personal message on the right heel, you can honor someone or something that holds unique meaning to you. Nike React foam ups the comfort to help keep you ready for high-intensity cardio. Plus, a tab locks down your laces, so you can forget about them coming untied when you're focused on your next PR. Spring in Your Step Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. It makes a comfortable, cushioned base that feels lightweight and springy when you kick it into high gear for cardio and sprints. More 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 intervals. Grip from All Angles Revamped rubber wraps up your arch for intense grip during rope climbs. Rubber tread gives you traction from the training room floor to the pavement.
