Inside Nike's "Adaptive Traction," the Wolverine of Soccer Shoes

The cleats can actually extend in response to soggy ground conditions. Here's how they work.

At a big, blow-out event in London last week, Nike unveiled its splashiest innovation, in advance of the 2010 World Cup: The Mercurial Superfly Vapor II football boot (or "soccer shoe," to Americans). Aside from the hotrod looks, the most intriguing innovation was the "adaptive traction technology," which allows the pegs of the cleats to actively adjust to turf conditions. Say what? How's that happen?

"From pitch to pitch, and even within a single pitch, the ground conditions vary," says Andrew Caine, Nike's creative director for soccer footware. "Pro players vary their boots to adjust, so we had a vision of shoe that would adapt." Three years later, the Vapor II has studs that extend up to 3mm in soft ground, but act like a normal stud on firm ground.

"In design, the simpler the mechanism, the better something works," says Caine. For the Superfly II, there are three basic components that allow the pegs to adapt. The structural support for the shoe comes from a carbon-fiber "plate" in the sole. Meanwhile, the bright orange pegs on the front of the shoe have a moving column inside. (Which you can see in the picture below—it's the black core.)

When a player steps into soft ground, the carbon sole flexes, pushing those columns down. The clear coating on the outside of the sole stretches in response, thus allowing the pegs to literally extend—while also keeping the entire mechanism sealed off from water and mud.

After impact, the coating then pulls the pegs back into place, and keeps them from driving back up into the foot.

The colors, meanwhile, are meant to be a performance enhancer for the entire team. The orange swoosh is meant to be a bold contrast with the green soccer pitch, thus making teammates easier to spot in a player's peripheral vision while he's on the run. And that's the same reason the outside is purple and the inside is dark: "The contrast creates a visual flicker that engages the peripheral vision," says Caine.

    I signed up just to say this....cleats? Wtf? They are boots, football boots. Shoes is acceptable as well I suppose, but cleats is just a silly word.

    We also call "football" soccer here in America so quit being so limy on America's interweb you wanka.

    This new technology could change the game for years to come. The added agility that comes from the new technology traction acts as a steroid of sorts, making athletes that much faster, which is obviously a huge advantage in futbol. I remember when Nike came out with a new type of baseball cleats that were supposed to do something similar, gaining traction on the dirt base paths. Those cleats are still around today, so I would expect these cleats to be around the game for quite some time.

    Well, It didn't take long! Did anyone notice that Clint Dempsey was wearing the Lavender "Mercurial" shoes when he scored what some sportswriters are calling the European "Goal of the Year" in Fulham's 4-1 victory over Italian giants Juventus in the Europa Cup match yesterday. Well Done indeed!

    Here's the problem with all football(soccer) cleats ... a lot of attention is spent on the outside of the cleats. The inside is this no-support, flat surface, and totally low-tech solution. Zero comfort for your feet. Why?? Any $30 shoe offers better comfort for your feet than these $150 cleats.
    It doesn't make sense.
    The first manufacturer that figures this out, will make a fortune!!!

    While The Mercurial Superfly Vapor II football boot is a mouthful for a name, this has some real appeal. As a year-round competitive soccer player here in Michigan, I have played on wet, hard, snowy, and various indoor turfs in the last year (the price we pay for 4 seasons) and the shoes I wear are not always the best performing on all terrains. Once I get a shoe that fits great and allows good ball control, I stick with it - if that shoe had cleats that adjusted to the playing surface that would be ideal! Nice job Nike (I currently play in Nike's). Maybe by the time the 2010 World Cup is over we will be calling them Air-Donovan's. Go USA!
