(EUC) Adidas Women’s Ultra Boost 20 Cloud White Gold Metallic Heel (Size: 7.5). The Women’s Adidas UltraBoost 20 'White Gold Metallic' delivers a pristine take on the lightweight and responsive runner. The sneaker's knit construction is made with Primeblue, featuring at least 78% recycled material that includes Parley Ocean Plastic.
