adidas Yeezy Foam Runner Onyx develops the familiar adidas Yeezy Foam RNR profile through a specific colour treatment and details created for this edition. Black Onyx emphasizes the organic openings and the solid sculptural silhouette. Organic openings and a flowing shape remain the Foam RNR's main visual signature, while each specific shade changes the model's overall presence. Lightweight foam softens each step, while open sections support airflow and the structured underside adds traction.
