Squats. Sprints. Circuits. The shoe that doesn’t know how to sit still is now part of our sustainability journey. Made for quick movements, max heart-rate spikes and an applause-worthy amount of reps, the Nike Air Zoom SuperRep 2 Next Nature is the fitness shoe you love with a thoughtful new design that reduces waste without sacrificing performance. It clocks in with at least 20% recycled material by weight, including Nike Grind, plastic bottles and other scraps. Tuned for Comfort An improved fit includes a fully adjustable tongue that lets you step in, cinch down and pour everything you've got into your workout. Another update is a generous forefoot to keep it comfortable for a wide range of foot types. Spring in Your Steps Every time you land on your forefoot, 2 powerful Zoom Air units absorb your energy and send it right back—launching you into your next step or jump. A full-length plate distributes the energy, helping balance your foot. Side-to-Side Support The big arc on the side acts as a brace for your foot when you’re cutting hard from side to side. The mesh ribbing on top—stitched in and tighter on this version—helps keep your foot snug during moves like lateral bounds and side lunges. Flexibility on the Floor A divide right under a natural flex point lets your foot bend effortlessly so you can stay stable while holding a plank—and attack mountain climbers and burpees like it’s your job.
