Drawn from adidas' eight-piece City Pack, the UltraBoost 2020 'Osaka' pays homage to Japan's port city with a design that blends a black Primeknit upper with a tri-tone Boost midsole, complete with 'OSA' lettering at the heel. Additional details include printed laces, contrasting red three-stripes and a 3D heel frame that cradles the back of the foot. It all rides on a black Stretchweb outsole, built with Continental Rubber for grippy traction.
