Using these New Balance 880V13 running shoes is easy. Just lace them up securely using the adjustable laces for a snug fit. They're great for everyday running, jogging, or even casual walks. When it comes to maintenance, clean them regularly with a soft brush and mild soap. Avoid using harsh chemicals as they might damage the synthetic/mesh upper. Let them air - dry naturally. Don't expose them to extreme heat. For the best performance, replace the shoes when you notice significant wear on the outsole. Also, keep in mind that the 10mm drop is approximate due to manufacturing variances.
