Adidas Running has today unveiled new colorways of the beloved UltraBoost and an updated version of the UltraBoost X, as part of the brand's new campaign "Energy From The Ground Up."

According to Adidas, the ventilation holes of the original UltraBoost return to the upper across the foot’s key sweat zones – the cage and forefoot. Combining this with a newly developed PrimeKnit composition, designed for reduced stretch to provide runners with a prime fit and additional support, the UltraBoost is a truly unique proposition. The silhouette also features a high-tech Fit Counter integrated within the heel to enable free movement of the Achilles tendon while complementing the built-in BOOSTTM midsole, providing the wearer with adaptability, cushioning and energy return. 

The new UltraBoost X takes learnings from the UltraBoost Uncaged and the Adizero Sub2 running silhouette, in which the cage and support features moved to the inside to give the silhouette a sleeker aesthetic for women. Fusing this aesthetic with modern, female-specific design features, including the Adaptive Arch, which permits the PrimeKnit Upper to mold to any foot while moving in sync with the wearer’s running style, the UltraBOOST X guarantees style and function. The integration of a purposely sculpted BOOSTTM midsole complements the Adaptive Arch design, allowing the elements to work together to provide enhanced support and cushioning. A 3D Sculpted Heel Counter is also designed to allow the Achilles tendon to flow vertically while keeping horizontal movements on lockdown.

The Adidas UltraBoost and UltraBoost X colorways shown in the gallery above will be available on adidas.com for $180 starting tomorrow, February 21 and in adidas stores worldwide starting February 28th.
