Adidas has officially launched its most technically-advanced running shoe, which incorporates a Primeknit flat kntted upper. The company launched Ultra BOOST, at an event in New York today, with the help of athletes Sammy Watkins, David Villa, Yohan Blake, Wilson Kipsang, Jenn Suhr, Tori Bowie and Ajee Wilson.

Ultra Boost’s carefully-engineered Primeknit upper is said to provide a precision fit and maximum breathability, while the midsole technology returns energy with each step. Primeknit was the world’s first running shoe with flat knitted uppers and was launched at the 2012 Olympics in London. Since then the flat knitted shoes market has boomed.

The full-length BOOST midsole is comprised of 3,000 energy capsules – 20% more than any shoe to date, according to the sportswear brand. “To answer the world’s athletes’ call for more energy we aimed to create the greatest running shoe ever and we’ve done exactly that with Ultra BOOST,” said Eric Liedtke, adidas executive board member. “Adidas has raised the industry standard with BOOST and will continue blazing a path in energy running for those who dare to follow.”

Elastic design

A Stretch Web outsole with a perforated, elastic design puts runners closer to the BOOST cushioning, allowing them to maximize the energy-return benefits, according to the manufacturer.

A new heel construction comfortably cradles the foot and adjusts to the Achilles tendon's natural movements. For a customized fit and feel, a new, featherweight sock liner is designed to adapt to runners’ individual foot forms.

Ultra BOOST also boasts a new dual-density TORSION SYSTEM, embedded into the shoe’s base. This, according to adidas, allows for more independent movements between the heel and forefoot, giving runners superior stability and a smooth, controlled run.

Ultimate comfort

To ensure Ultra BOOST can deliver ultimate comfort and energy return mile after mile, the company put the shoe through the ARAMIS testing system most commonly used by institutions including NASA, Boeing and Audi.

“Each technology featured in Ultra BOOST was built to complement each other providing energized adaptability through a customized fit, look and feel,” said Ben Herath, Vice President of Design for adidas Running.

“While we’ve taken innovation to the next level, the sleek silhouette of Ultra BOOST is built to look as good as it performs.”
