In 2013, adidas launched Boost foam and used it in EnergyBOOST running shoes, what really made Boost foam famous was Adidas' UltraBoost midsole foam technology in 2015 and the launch of the UltraBoost series of running shoes, which completely shocked the running shoe circle at the time.
UltraBOOST的名称为"发泡热塑性聚氨酯",简称 E-TPU。 E-TPU的全称是Expanded-Thermoplastic polyurethanes,其中E就代表了Expanded,意思就是扩大的。
TPU can be foamed to expand up to 10 times its original volume like popcorn, and is lighter, cushioned, more regenerative and more durable than traditional EVA materials. Since the technology was first introduced, Adidas has been exploring it in depth.
It's been almost a decade since Adidas first launched Ultraboost in 2015, and now Adidas has completely redesigned its most popular running shoe with its fifth innovation.
On July 12, 2024, Adidas announced that the latest Ultraboost 5 and Ultraboost 5X will go on sale.
Adidas hailed the new Ultraboost 5 as the "biggest redesign" of UltraBOOST since its launch, with a completely rebuilt build that delivers the highest energy return of any UltraBOOST shoe to date, thanks to a new geometry that makes the heel and midfoot more responsive. Reduces weight, improves cushioning and increases forefoot energy return by 2% compared to Ultraboost Light 1.
The Ultraboost 5 midsole features Adidas' latest LIGHT BOOST technology, which delivers all the benefits of standard BOOST foam while reducing weight. Other technical improvements include the Primeknit upper, which weaves tighter in high-wear areas and looser in less stressful areas for enhanced breathability.
In addition, there is a modern version of Adidas' classic Torsion midfoot support system and a premium Continental rubber outsole.
Color-wise, the UltraBOOST 5 comes in a colorway that combines a subtle white and "Glory Grey" upper, while the midsole features a vibrant "Spark Orange" and "Lucid Pink" combination. Represents the burst of energy released by the shoe.
The new versions of the Ultraboost 5 and Ultraboost 5X are the shoes with the highest energy return in the Ultraboost family to date.
Simon Lockett, Director of Product Marketing for Footwear at Adidas, said: "Ultraboost is a true running icon and this is our best product to date. ”
"Eighty-two percent of testers said they preferred the energy return of the shoe, and 70 percent said they enjoyed running in the shoe more," Lockett said. This has always been a great feature of Ultraboost, especially now that it's back, and the Boost is stronger and weighs less than before. ”
