Here's a Tier Zero look at the new Lunar Racer which combines the Flywire tech with the ridunkulously lightweight Lunarlite foam. With a modest cool white exterior, this version has been embellished with Flywire threads that could possibly, if we were to take a wild haymaking guess, reference the Olympic rings colours... This unit will be available in the usual outlets as well as at the opening of the Mercer 21 Nike Sportswear store in New York.
For the full effect, you really need to pick this sneaker up, and when you do, you'll be blown away by how little this thing weighs. Try 5.5 ounces to be precise... Not sure how that figure compares to the Mayfly, but this thing is a lot more practical and stable. We've been calling for some new-wave design to come through for a while now, and Nike have answered our prayers and delivered us the Lunar Racer. Rejoice! We can dig it! Hopefully enough like-minded cats out there can also feel the heat of this modern love.... applause where applause is due, this type of sporting-tech investment has many jaded heads finally raising an eyebrow or two. Time to get back into the game!
Given Flywire’s early success with middle-distance Track and Field events, bringing its lightweight support to distance racing seemed natural. So, too, did marrying the technology with Lunarlite foam, Nike’s most advanced new cushioning system. Flywire works like cables on a suspension bridge, providing precisely engineered support for the foot. The Flywire filaments are placed only where support is required, allowing for the reduction of materials, which equals reduction of weight. Made with Flywire, an upper weighs mere grams, while Lunarlite foam is both lightweight and highly responsive, two qualities which are usually mutually exclusive in cushioning. The foam also distributes the pressure patterns evenly across the foot more to protect it from pain and injury—all important for distance events. In the Nike Zoom Victory Spike—designed for middle distance Track and Field events—Flywire proved a great success in competition. After Nike athletes Kara Goucher and Bernard Lagat both medaled in the 2007 World Track & Field Championships in Osaka, designers looked at where else the innovation could be applied. The marathon was a natural choice.
On race day, marathon runners sacrifice cushioning. It’s not responsive enough, meaning that it absorbs too much energy so marathoners end up expending more energy as they run. The race might be more comfortable but it’s more work, and at 26.2 miles, energy conservation is critical. Nike designers didn’t think distance runners should have to sacrifice either in a road race, so they came up with a lightweight racing flat, the LunaRacer, that wasn’t stiff, that was soft and returned energy to the athlete. Articulated with flex grooves, the LunaRacer’s outsole follows the foot’s natural motion, while Flywire works with the foot, stretching where an athlete needs it and providing support where it’s needed—almost like an extra ligament. Over the metatarsal area, Flywire gives an important feature in a grueling road race, while simultaneously locking down the midfoot and heel.
The design team found that with a more flexible midsole and outsole, a Flywire upper has a more dynamic fit. As the technology’s creator Jay Meschter explains, “We started to realize the relationship of the bottom of the upper. Because you have an upper that's holding the foot accurately, when you put on firm outsoles, they compromise the fit. With a compliant, moveable outsole, you can actually feel the cable all the way around the foot instead of just landing on this hard plank on the bottom of your foot, which causes the Flywire upper to tent out to the side.” The LunaRacer weighs a mere 5.5 ounces, and elite athletes who’ve experienced Lunarlite foam cushioning are reporting that after their long runs they feel less beat up—a good sign for the marathon in Beijing.
