Use a soft brush or cloth to remove surface dirt after each wear, focusing on seams and the sole edge. For leather panels, apply a neutral cream sparingly and buff to maintain suppleness; for polyester sections, spot-clean with a damp cloth and mild soap, avoiding oversaturation. Let sneakers dry at room temperature and store them with shoe trees or paper stuffing to hold shape. Avoid harsh chemicals or aggressive washing, which can damage both the leather and technical components.
