NEW YORK – In an impressive launch event in front of some 400 media from around the world, adidas unveiled Energy Boost, its new running shoe, which the company feels will be a “game changer” in midsole technology.

The Energy Boost is unlike traditional shoes that use EVA in their midsoles, substituting BOOST, a revolutionary cushioning technology which provides the highest energy return in the running industry.

As part of the presentation, a steel ball was dropped onto concrete, a sheet of EVA, and a sheet of BOOST. The rebound from the BOOST was significantly higher and longer lasting than off the other surfaces.

According to Eric Liedtke, Head of Sport Performance at adidas, BOOST combines performance benefits that have been contradictory in the past: soft cushioning and responsiveness. “It’s like combining a limousine and a sports car,” he said. “In the past, you had to choose between a soft ride or peformance. Boost provides both. Most changes in running shoes have been evolutionary; this is revolutionary.”

The company trotted out some big guns to promote its new technology: 100 meter world champion Yohan Blake and multiple distance event record setter Haile Gebreselassie, who joked that “the IAAF may start looking at this to see if it’s legal.”

The foundation of the BOOST midsole is based on a groundbreaking development process created by adidas partner BASF, the world’s leading chemical company. Solid granular material (TPU) is literally blown up and turned into thousands of small energy capsules which make up the footwear’s distinctive midsole. With their unique cell structure, these capsules store and unleash energy more efficiently in every stride. Tests conducted by the adidas Innovation Team show that the highly durable material found only in Energy Boost products provides the highest energy return in the running industry.

Almost as important, BOOST retains these properties much longer than EVA, which tends to compress and lose its cushioning over the life of the shoe. In contrast, BOOST is just as resilient after 300 miles of running as it is out of the box.

Changing temperatures, which can also affect EVA, making it hard in the winter and soft in the summer, don’t change the cushioning and energy return properties of BOOST. Tests revealed that, when taken from +40 to -20 degrees Celsius, BOOST foam is three times more temperature-resistant than standard EVA material, providing a more consistent run.

While the midsole is the centerpiece of  the Energy Boost, the upper has not been neglected. It features adidas Techfit technology with highly durable and elastic polyurethane, providing optimal comfort and support to the entire foot while in motion. A stretch, breathable mesh material offers the fit of a sock while engineered powerbands across the upper provide targeted support and stabilize the foot where needed when moving. The company plans to expand the use of BOOST technology into its other top of the line shoes over the course of the coming year.
