The adidas UltraBoost 4.0 DNA 'Black Hearts' is a stylish variant of the popular running shoe that features a predominantly monochromatic design with a twist of subtle multicolor accents. Its sleek black Primeknit upper is complemented by a supportive midfoot cage adorned with small blue, green, and red hearts on the side. These hearts are cleverly transposed to the black sidewall of the Boost midsole, enhancing the overall aesthetic. Adding a vibrant touch, a Solar Red heel strip contributes an extra burst of color to this visually striking sneaker.
