The shoe features improved midsole technology and an enhanced upper fit that promotes the foot’s natural movement.
At a press event in New York City on Thursday morning, adidas unveiled the new Ultra Boost—a running shoe the 65-year-old German company is calling “the best ever made.”
The shoe, which weighs in at just under 11 ounces in a men’s size 9 and has a 10 mm drop (30.5mm/20.5mm stack heights), features a new Ultra Boost foam, a proprietary cushioning platform packed with 3,000 energy capsules compared to the 2,000 found in the standard Boost foam that graces most of adidas’ robust performance running shoe lineup. The new foam is said to be more temperature resistant than traditional midsoles, which helps it to provide a consistent feel in a variety of conditions.
Ben Herath, vice president of design for adidas Running, says the Ultra Boost foam provides unmatched energy return from the ground mile after mile. Its midsole is designed to feel consistent underneath your feet throughout the life of the shoe—that’s right, it claims to ride just as well at mile 500 as it did at mile 5. We haven’t been able to wear-test the shoe yet to substantiate this impressive boast, but stay tuned for an upcoming review on Competitor.com for a full overview on how this shoe fits, feels and rides.
“Each technology featured in Ultra Boost was built to complement each other providing energized adaptability through a customized fit, look and feel,” Herath says. “While we’ve taken innovation to the next level, the sleek silhouette of Ultra Boost is built to look as good as it performs.”
Aside from introducing the new Ultra Boost technology—which is built around a dual density Torsion system that is firmly embedded into the midsole, providing midfoot support and allowing for more independent movements between the heel and forefoot—the shoe’s lightweight upper is made of a woven one-piece material called Primeknit, a carefully engineered mesh that keeps your foot locked in place while reducing irritation and providing ventilation in a variety of conditions. The external heel counter of the shoe is designed to provide stability around the heel while a smartly designed cutout allows the Achilles tendon a frictionless freedom of movement. A small plastic wedge embedded into the midsole on the medial side of the heel provides mild stability for rear-foot strikers. Underneath, the shoe’s new stretch web outsole is designed to support the foot’s natural movements while providing an enhanced feel for the ground that can adapt to a variety of surfaces.
“The stretch web stretches in any direction where most midsoles are rigid,” explains Heiko Schlarb, a senior researcher at adidas. “The traditional flex grooves in most shoes only move front to back. We made stretch web adaptable because runners strikes the ground in a variety of ways.”
The new Ultra Boost will be available beginning on Feb. 11 and comes with a price tag of $180.
