The Adidas UltraBoost 4.0 'Non-Dyed White' is a clean and stylish sneaker that is perfect for any outfit. The one-piece Primeknit upper is white with black peppered in for contrast, and the desaturated aesthetic is complemented by a pristine white midfoot cage, heel counter, and Boost midsole. The Continental rubber outsole is black, providing a sleek and sophisticated look. Released in December 2018, this clean rendition of the UltraBoost 4.0 silhouette features a ‘Non-Dyed White’ colorway.
