The adidas Ultraboost 21 low-top running shoe with smooth cushioning and rebound

The adidas Ultraboost 21 low-top running shoe with smooth cushioning and rebound performance has been updated with a new look. The Ultraboost 21 replaces the traditional PK upper with a newly woven, textured Primeblue material upper, incorporating environmentally friendly elements for a richer visual experience and superior stability. The thickened Boost material is visually visible, and the slightly exaggerated design creates unprecedented tension and enhanced rebound and cushioning. The outsole has also undergone significant changes, consisting of three sections. The forefoot edge and core areas remain Continental rubber, while the heel and forefoot connection feature a transparent, textured outsole, adding a richer visual effect. Details also reveal translucent TPU supports on the sides and a slight change to the TPU support at the heel, further enhancing the overall look. This evolution represents a significant overhaul for the Ultraboost, promising a stronger, more comfortable feel.
