Inside Access: The Story of Nike Lunarlon

Inside_Access_Lunarlon_26077

Almost a decade ago Nike designers Kevin Hoffer and Eric Avar put their heads together to confront a challenge. Marathon runners typically take around 40,000 steps from start to finish – they needed a shoe to withstand the relentless impact and to put a spring in their stride. Meanwhile, elite basketball players needed a shoe to cushion their high-impact jumping and provide quick push-off for explosive changes of direction.

Hoffer and Avar began the search for the right material, an ultra-lightweight foam that was both pillowy-soft and rubber-ball bouncy. They drew inspiration from images of astronauts walking on the moon. The astronauts’ weightless, soft and springy movements were exactly what the designers were trying to provide for athletes.

After failing with countless materials, there came a breakthrough. Found way in the back of the Nike Advanced Material Interest Group’s closet, the team unearthed a space-age foam. In science terms, it was the fusion of lightweight Ethylene Vinyl Acetate (EVA) with the bouncy ball-like spring of Nitrile Rubber (NBR).

The team’s experiments helped it take another leap forward in 2005, when it created a prototype of a Lunarlon-cushioned running shoe sole. The team squeezed a soft-but-stable Lunarlon center into a firmer and supportive Phylon foam shell.

Then they presented the prototype to colleagues.

“We had an immediate ‘wow!’ reaction,” says Hoffer. “It was a real breakthrough to have such great cushioning – a running-on-pillows feel – in such a lightweight shoe.”

EXPANDING HORIZONS

Lunarlon technology debuted in two new shoes in time for the summer of 2008 in Beijing, the Nike Lunaracer for the marathon and Nike Hyperdunk for basketball. Hoffer, Avar and their team had struck gold. Athletes of all levels loved the way Lunarlon minimized impact while providing both spring and support.

Back at Nike World Headquarters, designers’ interests were piqued. They began exploring how the wonder technology could benefit athletes in other sports by adapting it for sport-specific needs. Training, skateboarding, golf and snowboarding athletes alike wanted to see the foam’s performance capabilities in their shoes, too.

Adapting the foam led to innovative shoes like the Nike SB Eric Koston 1 skateboarding shoe, featuring a drop-in Lunarlon sockliner/midsole combo that helped soften the impact from performing tricks without dampening board feel.

Men’s and women’s training shoes also benefited from Lunarlon, which provided responsive and lightweight cushioning versatile enough to handle a variety of movements, from sprints to squats.

Lunarlon presented new opportunities to design shoes for all types of runners. In 2008 the Nike LunarGlide debuted with Dynamic Support, a two-part midsole system developed to provide stability and cushioning. Lunarlon was the perfect soft density foam to cushion runners’ heel impact, while a firmer density foam wedge helped stabilize pronation as the foot flexed down.

Hoffer and Avar’s team created more than just a new tool in the design toolbox – they transformed perception. The old rule that a lot of cushioning always required a lot of shoe was overturned.

THE BEST OF BOTH WORLDS

Hoffer and Avar’s team accomplished their mission. With Lunarlon, runners, basketball players and athletes from a variety of sports can choose to have both soft cushioning and bouncy responsiveness.

In August 2013, Kenyan distance runner Edna Kiplagat crossed the finish line in Moscow, Russia, to win her second world championship in the marathon. On her feet were custom-designed Nike shoes with Lunarlon foam.  From everyday workouts to the most pinnacle sport moments, athletes around the world have a little more spring in their step with Nike Lunarlon.
