LEGO x UltraBoost 21 J 'Color Pack - Red'
The LEGO x adidas UltraBoost 21 J ‘Red’ is taken from the kids’ ‘Color Pack,’ comprising assorted UltraBoost styles inspired by the iconic Danish toy manufacturer. This pair is rendered in a simple two-tone palette that pairs white textile with crimson accents on the signature three-stripes and heel counter, both of which feature a studded texture redolent of classic LEGO bricks. A matching red finish is applied to the full-length Boost midsole, reinforced underfoot by a black Stretchweb outsole made with grippy Continental rubber.
