As part of the kids' 'Color Pack', the LEGO x adidas UltraBoost 21 J 'Shock Blue' is being launched. This sneaker showcases a Cloud White textile upper with reflective detailing in the forefoot. The suede forefoot overlay, three-stripes, and molded heel counter are highlighted with contrasting blue accents, reminiscent of LEGO bricks. Comfortable cushioning is provided by the full-length Boost midsole, which is complemented by a Stretchweb Continental rubber outsole for support. The tongue tag and sockliner are adorned with both LEGO and adidas branding.
