To use these New Balance running shoes, simply lace them up tightly for a secure fit. When you're out running, enjoy the soft step and great support they provide. As for maintenance, you can use a soft brush and mild soap to clean the mesh upper. Let them air - dry, and avoid direct sunlight or heat sources as this could damage the materials. Also, check the soles regularly for signs of wear. If the traction seems to be decreasing, it might be time to replace them. Remember to store them in a cool, dry place when not in use.
