Limited to 20,000 pairs in Japan for the first model!

The most significant feature of the "energy boost" running shoe is the world's first adoption of "BOOST™ Foam," a new material that combines the seemingly contradictory functions of "shock absorption" and "energy return."

This revolutionary sole material, BOOST Foam, was born from the collaborative development efforts of adidas, adidas's research institute "a.i.t. (adidas innovation team)," and BASF, a German chemical company and adidas's technology partner.

After 3 Years of Development, the Revolutionary New Material "E-TPU" is Complete

Since the late 1960s, EVA (Ethylene-Vinyl Acetate) material, which is easy to shape, has been primarily used for shoe midsoles. While EVA is a versatile material that can enhance shock absorption and energy return by adding composite materials, it had challenges regarding changes in hardness due to external temperature and durability.

Therefore, adidas focused on TPU (Thermoplastic Polyurethane Elastomer), a highly versatile polymer material. They devised a new manufacturing method: foaming TPU, which excels not only in lightness, durability, and impact strength but also in low-temperature flexibility and elasticity across a wide temperature range, before molding the material.

"E-TPU," BASF's TPU foamed into individual pellets, was molded into a sole shape using a high-pressure, specialized manufacturing process. By molding it as an aggregate while retaining its CELL-like foamed structure, a unique sole with a distinctive texture, characterized by its three-dimensional and memorable foamed appearance, was created.

After three years of development, "E-TPU" was completed in 2010. Through repeated trials, test runs, and improvements to ancillary materials, the energy boost was finalized.

Highly Durable Material with Minimal Sole Degradation Even After 500km of Running

BOOST Foam, with its fine, uniform, closed-cell structure trapping tiny energy capsules, provides long-lasting shock absorption and energy return. In the newly released "energy boost" running shoe, BOOST Foam is used as a single material throughout the entire sole. This allows for immediate energy return upon ground contact, reducing ground contact time and enabling an exhilarating, comfortable run.

At the press conference held on February 21st (Thursday) at the Tokyo Marathon EXPO 2013 venue, Norio Sasaki, coach of the Japan Women's National Football Team (Nadeshiko Japan), Yuki Ota, silver medalist in team foil fencing at the London Olympics, Kayoko Fukushi of the Wacoal Women's Track and Field Team, Miwa Asao, sports journalist Akemi Masuda, and adidas contracted physical trainer James Shuichi Nakano took the stage. The discussion about the appeal and potential of the energy boost was lively.

BOOST Foam, the latest material, expands the possibilities for all adidas products, not just running shoes. The dedicated energy boost website (http://adidas.jp/boost) features testimonial videos from celebrities, allowing you to experience the "unknown run" from various perspectives.

Furthermore, an energy boost experience event will be held on March 9th (Saturday) and 10th (Sunday) at Shinjuku Station Square (in front of Alta) in Shinjuku, featuring a giant 8-meter long running machine. Don't miss this event either.
