You chase the clock, challenging and encouraging each other all in the name of achieving goals and making gains. Our go-to model for training relies on a lighter, more breathable upper than our previous edition to complement our standards of durability and comfort, so that you can float through your cardio, power through your lifts and dominate your workouts. 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. More Benefits 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 helps minimise drag during wall exercises. Grooves in the sole let your forefoot bend naturally.
