Drawn from the kids’ ‘Color Pack,’ the LEGO x adidas UltraBoost 21 J ‘Multi’ showcases a familiar blend of colors inspired by the world-famous Danish toy brand. The lifestyle runner makes use of a white textile upper with a blue suede forefoot overlay and yellow TPU midfoot cage. Reminiscent of LEGO bricks, a studded texture distinguishes the external heel counter and signature three-stripes, rendered in contrasting green and scarlet hues. A reflective no-sew overlay offers added visibility along the forefoot. The sneaker’s tooling brings together a full-length Boost midsole and Stretchweb Continental rubber outsole.
