How to use: Just lace up these New Balance 1080V13 shoes and you're ready to hit the road or the track. They're great for running, but also suitable for casual walks. Notice: The 6 mm drop is approximate because of manufacturing differences, so keep that in mind if you're very particular about the drop. When choosing a size, make sure to consider your normal running shoe size. Maintenance: To keep your shoes in good condition, clean them regularly with a soft brush and mild soap. Let them air - dry away from direct heat. Avoid machine - washing as it might damage the shoe's structure. If you have the Holiday pack version, be a bit more careful with the metallic accents to prevent scratching.
