HOW NIKE BUILT THE REAL POWER-LACING SNEAKER OF OUR DREAMS.

The Sneaker should come alive. Tinker Hatfield was sitting at a drafting table in his office in Beaverton, Oregon. He and another young designer at Nike named Mark Parker had just returned from a brainstorming session in Hollywood with film director Robert Zemeckis, who was storyboarding the sequel to his sci-fi comedy hit of three years earlier, Back to the Future. It was 1988, and Zemeckis and his creative team were on the hunt for futuristic sight gags for the film, set in 2015. They had tasked Hatfield and Parker with dreaming up some seriously 21st-century sneakers. One idea that came up in the meeting involved magnetic levitation, but to Hatfield that seemed a little too Jetsons.

His time as a pole-vaulter and his degree in architecture from the University of Oregon had taught him to prize utility, and it didn’t seem plausible to him that any athlete, even decades in the future, would ever want or need to levitate. Hatfield and Parker decided to treat the assignment not as a sight gag but, as he recalls, “like someone had asked me to reinvent footwear for actual performance reasons, in the real world, only I had 30 years to figure the technology out.” And that’s when the idea came to him: “What about a shoe that would essentially come alive when you put it on? It would sense you. It would become the shape of your foot, and when it came alive it would light up. Wouldn’t it be great if shoes could do that?”

Hatfield didn’t just sketch what such a shoe would look like. He drew a storyboard in which Marty McFly first encounters a pair of sneakers: He steps in, reaches down to tie the laces—an instinctual, ritual bowing down to the shoe—and the sneakers light up, come alive, and shape to his foot. (Hatfield says he even included a snippet of McFly dialog—something like Wow! Power laces!) A scene similar to Hatfield’s drawing wound up in the movie, which became one of the highest-grossing films of the year and introduced the Nike Mag, as the shoe was christened, as something like the flying car of footwear—a sci-fi promise that nobody could figure out how to deliver on. Over time, the Mag would so capture people’s imaginations that an intense campaign resulted in online petitions, with futurists, fanboys, and sneakerheads pleading with Nike to create a retail version.

Nike’s Sneaker Gurus Demonstrate the HyperAdapt

Hatfield, Parker, and an army of designers, engineers, and data scientists were listening. And after 28 years of brainstorming and 11 years of R&D, after many false starts, delays, and blown deadlines, after the vanquishing of internal skepticism, after innumerable prototypes, iterations, and redesigns, Nike’s automatic electronic self-lacing shoe is scheduled to ship to stores this holiday season. The company is calling the technology “adaptive fit,” and the sneaker is the HyperAdapt 1.0—each shoe has a sensor, battery, motor, and cable system that adjusts fit based on an algorithmic pressure equation. When a foot is inserted, the shoe tightens automatically until it senses friction points. There are a pair of buttons near the tongue to adjust fit as needed. That such high tech shoes, with a likely (though still TBD) high price tag to match, would be desirable in a country that spends billions a year on sneakers was almost taken for granted. That Hatfield, now Nike’s vice president of creative concepts and probably the world’s most celebrated designer of shoes, a human icon inside a corporate one, would lead the team behind them was only expected. And while no one will say how much the company has spent on the shoe’s development—“a considerable amount of R&D dollars” is as specific as Parker, now the company’s CEO, will get—Hatfield believes the HyperAdapt is the first step in a revolution in adaptive footwear and thus worth every red cent. “We’re talking about a project that’s maybe the most difficult in the history of footwear,” Hatfield says. “I’m more excited about this than any project I’ve ever been involved with.”

For Tinker Hatfield, the idea of a self-lacing shoe is of a piece with technologies like the Internet of Things or self-driving cars.

The thinking was rooted in enhancing athletes’ abilities and protecting their bodies. “Most of the athletes we observe—scientifically and otherwise—their feet are ruined,” Hatfield says, reclining in a love seat near his desk, his curly gray hair frothing up professorially and his pole-vaulter’s physique more or less intact at 64. “Here’s a thing that I believe, and I think it’s been scientifically proven: If your feet are not healthy, there’s kind of a chain reaction, and your entire body can get out of whack.” Take pro basketball players, he says: “If you’re playing for three hours, there might be only an hour of it when you actually need your sneakers tight. The rest of the time, when you’re standing around for free throws, jump balls, sitting on the bench, you should loosen your shoes up.” But NBA players don’t do that, he explains—“so day after day after day they’re torturing their feet, and they’re becoming less and less healthy.” This was a performance problem, Hatfield reasoned, that required an engineering and design solution. By 2005, with interest in the Nike Mag still pulsing, he and Parker believed that technology had advanced enough to make adaptable performance a reality.

Beers, ambitious and energized by the call from the resident guru, set off on the project, with Hatfield and the other designers largely taking a backseat. This is how a project generally works at Nike: The heavy design work doesn’t commence until the engineering is mostly worked out. There was no deadline for Beers and no budget. To start she paid a visit to Nike’s enormous archives—run by a former Nike shoe designer who had also been a curator at Chicago’s Museum of Science and Industry—and had him pull the original Nike Mag. The prop itself did not have an auto-lacing mechanism—in the movie, special-effects people constructed a platform, and under it several crewmembers lay on their backs and pulled a series of wires, invisible to the camera, that were attached to the shoes on Michael J. Fox’s feet. Beers also discovered that the lights in the shoe were electroluminescent and therefore electro-hungry. On the set, Fox had to carry a battery pack the size of a transistor radio in his back pocket, allowing the letters NIKE to light up in fluorescent blue on the Mag high-tops.

Every now and then the Nike brass convene in the Innovation Kitchen for what amounts to a high-stakes game of show-and-tell. Designers and engineers bring the prototypes for projects they’re working on, and top executives will consult, criticize, and question their progress. In January 2015, the HyperAdapt team brought their latest iteration into one of the Kitchen’s conference rooms. Beers, who’d been working nonstop since Hatfield’s NBA All-Star bombshell, had finally taken a vacation, and assuming her place was Eric Avar, another heralded Nike designer and Hatfield protégé, best known for his designs bearing Kobe Bryant’s name. As Avar wrapped up his presentation, the panel began eviscerating the entire project. They questioned just about everything. At bottom, Beers says, they doubted that the shoe had any real athletic benefit. Even more terrifying, they were unsure whether work on it should even continue. (Skepticism was and is hardly limited to inside Nike—in the wider industry, gimmick is a word that gets thrown around, and the Reebok Pump is sometimes dismissively referenced. “I look at it as more of a PR thing, not as true innovation,” says Peter Rueegger, a leading footwear-industry consultant who has worked with Nike in the past. And Mike Friton, a former Nike designer who worked closely with Beers on the project in its early stages around 2007, questions the environmental impact and sustainability of a shoe packed with electronics. “To me, it was kind of running backward in that sense.”)

When she returned, Beers once again did not panic. The panel’s feedback coaxed her team to focus on improving the HyperAdapt’s basic proposition: It could help protect athletes’ feet, and that, in turn, could help the athletes feel better and play better. “I was like, OK, we have to build more prototypes,” Beers says. “We have to have more people try it out, we have to prove it with numbers. We have to put the proof on the table.” With the help of Nike Sports Research Lab, a testing facility that measures human performance and collects data to shape the design and engineering, she conducted multiple rounds of what’s internally called perception testing. Beers put HyperAdapt prototypes on test subjects and had them go through a kind of CrossFit training routine, and after their workouts they answered surveys about their shoe experience. She also stepped up dynamic wear testing, where she asked runners and basketball players to wear the shoes and give her feedback on how their feet felt during and after their workouts. With new data in hand, Beers added sole cushioning and rejiggered the fit system so the lacing harnesses hugged less on the toes and more on the foot’s midsection, and subjects reported less wear and tear on their feet after intensive workouts. Six months later, with a new launch target of 2016 in mind, she presented a new HyperAdapt prototype to the Kitchen’s evaluation panel. The skeptics were satisfied.

A pair of HyperAdapts materializes in front of me. It’s late July in Beaverton, and these are samples, late-stage prototypes—Beers is even now testing and making tweaks to the shoe’s internal workings. She is currently wearing a pair of HyperAdapts. She in fact wears them all day, every day. “I want to know every challenge our consumers are going to face. I just want to know everything in order to make it better.” There are no swooshes on her pair. That way, when she goes out in public, prying eyes will be less likely to discern that she’s wearing a pair of top-secret Nikes.

She sees me gazing mutely at the shoes as if awaiting instructions. “All you have to do is step into it,” Beers says. The second I do so, the shoe emits an electric whizzing noise, like that of a child’s toy. It’s the noise you might make if you were doing the robot. The sound is weirdly satisfying, possibly because it occurs as the shoe embraces my foot in a gentle kind of hug. Not long ago, I sprained my right ankle in an embarrassing encounter with a flight of stairs. As a result, my right foot remains swollen. After the whirring subsides, I stand up and look down. On my right shoe the laces are visibly looser, but the grip is no less secure.
