Setup, Compatibility & Care
To ensure your Nike JA 1 trainers maintain their performance, begin by breaking them in with light activity before full-intensity use. These trainers are standard fit for adult male sizing; if you use custom orthotics, you may need to remove the factory insole for a better fit. For care, wipe down the white leather or synthetic surfaces with a soft, damp cloth after use to prevent dirt buildup. Avoid machine washing or drying, as this can degrade the specialized materials and adhesives used in the construction of the shoe.
