Setup, Compatibility & Care
To ensure the best performance from your Nike JA1 trainers, start by confirming your size—this model is specifically sized for the UK adult foot standard. When lacing, ensure a snug fit across the midfoot to maximize the internal support system. To care for your trainers, avoid machine washing. Instead, wipe the leather surface with a soft, damp cloth after use to remove sweat or dust. For tougher stains, use a mild leather-safe cleaner. Always allow your shoes to air dry naturally at room temperature away from direct heat sources, such as radiators, which can cause the leather to crack or lose its shape.
