Adidas expands their Ultraboost 4.0 line with an LTD rendition. This time around the sleek silhouette gets treated to a Cloud White/Silver Primeknit upper complimented by metallic silver UltraBOOST branding at the heel. Contrasting icy blue threads run throughout the upper, while the white TPU lacing system is complimented by light grey Three Stripe branding. As always, an Adidas tongue label and a Continental rubber outsole give the sneaker a finished look. Purchase your blue Adidas UltraBoost 4.0 LTD sneakers in-store and online today.
