UltraBoost 21 Primeblue 'Non Dyed'
The adidas UltraBoost 21 Primeblue ‘Non Dyed’ combines lightweight performance with a sustainable build. Designed to hug the unique contours of the foot, the undyed Primeknit upper is constructed in part with recycled Parley Ocean Plastic and zero virgin polyester. The sneaker’s supportive heel counter and midfoot cage maintain the blank-canvas aesthetic. Responsive cushioning arrives via a full-length Boost midsole, enhanced with adidas’ LEP Torsion System for increased energy return.
