If Tony Stark ever worked on a sneaker, it would probably look a lot like Nike’s new Project Amplify. Developed with robotics company Dephy, Project Amplify is what happens when Nike decides your calves could use some backup. The system acts like a “second set of calf muscles,” powered by a lightweight motor, drive belt, and rechargeable battery cuff. It’s not a gimmick either. Testers say running uphill feels like walking on flat ground.
Michael Donaghu, Nike’s VP of Create The Future, summed it up best: “Project Amplify started with a single question: What if we could find a way to help athletes move faster and farther with less energy and a lot more fun?”
So how does it actually work? Imagine a carbon fiber–plated running shoe wired into a small motor system strapped to your ankle. It kicks in just as you move, giving you a subtle push forward. Early testers say it feels surprisingly natural, which is impressive considering you’re wearing a robot. In one test, a runner shaved two minutes off their mile time—going from twelve minutes to ten. That’s the difference between “casual jogger” and “trying to impress your ex at the park.”
Nike and Dephy didn’t just wing it either. Over 400 athletes have tested nine different prototypes across more than 2.4 million steps. That’s roughly 12,000 laps around Nike’s Sport Research Lab track. Sean Ingle from The Guardian tried it himself and said, “At one point I jog up the 150-metre ramp on Nike’s campus which has a 15.63% incline – without being remotely out of breath.” Considering he did that with a bruised toe, that’s either witchcraft or incredible engineering.
The project isn’t aimed at elite runners shaving milliseconds off personal bests. It’s for everyday athletes—those running between a ten- and twelve-minute mile pace—who want a little help going farther or faster without gasping for air halfway through. Think of it as an e-bike for your legs. In fact, Donaghu compared it directly: “At its core, Project Amplify is about seamlessly adding a little more power to your stride.”
Nike’s research team has been testing this tech for years, refining the design and figuring out how to make it feel less like wearing an exoskeleton and more like wearing a really smart sneaker. One early tester even joked it could make New Yorkers walk so much they’d forget about taxis altogether.
It’s not just performance-focused either. For people with mobility challenges, Project Amplify could be life-changing. One Instagram user wrote, “As a disabled woman who wears an AFO, I really hope these are affordable and available to the average person. They could be life changing for many of us.” Another simply commented, “Take my money.”
Project Amplify still doesn’t have a release date, but Nike promises a broad consumer launch “in the coming years.” That gives you just enough time to start saving—or practicing your “Iron Man landing.”
