The adidas Yeezy Foam Runner Kids MX Sand Grey applies a swirling mix of colors to a slip-on silhouette built with injected EVA foam. The flexible material, made in part with harvested algae, showcases a neutral tan base with streaky brown, grey and coral accents that appear to be painted on. Ventilation ports throughout the vamp and side panels provide breathable comfort. Underfoot, the outsole features a wavy tread for reliable traction.
