The LEGO x adidas UltraBoost 21 J 'Multi' is a trendy lifestyle runner that perfectly captures the essence of the iconic Danish toy brand, drawing inspiration from the vibrant colors found in the kids' 'Color Pack.' Its white textile upper is complemented by a stylish blue suede forefoot overlay and a striking yellow TPU midfoot cage. To pay homage to LEGO bricks, the external heel counter and signature three-stripes feature a unique studded texture in eye-catching green and scarlet shades. Enhancing visibility, a reflective no-sew overlay is incorporated along the forefoot. In terms of performance, this sneaker combines a full-length Boost midsole with a Stretchweb Continental rubber outsole, providing optimal cushioning and traction for every step.
