The Nike Metcon 7 is the gold standard for weight training-even tougher and more stable than previous versions. Plus, a tab locks down your laces so you can forget about them coming untied when you're focused on your next PR. 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. Spring in Your Step Nike React foam makes a comfortable, cushioned base that feels lightweight and springy when you kick it into high gear for cardio and sprints. 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. Lightweight mesh with textured overlays in high-wear areas helps keep your foot cool without sacrificing durability. Tab locks down the laces with a hook-and-loop closure to help keep them out of the way. Handstand clip at the heel minimizes drag during wall exercises. Flywire cables integrate with the laces to help secure your midfoot. Grooves in the sole let your forefoot bend naturally.
