BRAND NEW, IN BOX, NEVER BEEN WORN!! The adidas UltraBoost 2.0 ‘Red Gradient’ showcases the silhouette’s classic design ingredients: a lightweight and breathable Primeknit upper mounted on a full-length Boost midsole. The red knit construction, embellished with a lighter shade of red and orange across the vamp, receives structural support from the matching red midfoot cage and a contrasting black heel counter.
