The adidas Yeezy Foam Runner Infants ‘Onyx’ delivers a tonal colorway of Kanye West’s innovative slip-on. The molded one-piece upper is built with injected EVA foam, rendered in a stealthy black finish and shot through with a series of strategically mapped vents for enhanced breathability. A sculpted heel and a soft, textured footbed provide a snug and comfortable fit. adidas branding appears on the outsole, featuring a wavy traction pattern for optimal grip.
