The UltraBoost 2.0 J ‘Triple White’ is a kids’ version of the shoe, featuring an all-white 2.0 Primeknit upper with breathable perforations on the toe box and collar. Supported by a tonal Three-Stripes cage and heel counter, a hit of color emerges on the metallic silver Ultra Boost branding. The sock-like runner rests on a white Boost midsole and a white Continental rubber outsole.
