Setup, Compatibility & Care
To get the most out of your Nike ReactX Infinity Run 4 Trainers, ensure you have selected the correct size; these trainers are designed to fit true to size. Before your first run, lace them comfortably—avoid overtightening the laces near the ankle to allow for natural flexion.
For care and longevity, avoid machine washing or drying the trainers, as high heat can damage the integrity of the foam cushioning and adhesives. If they become dirty, wipe the upper mesh and midsole with a soft, damp cloth using mild soap. Always let them air dry naturally in a cool, shaded area away from direct sunlight, which can cause the materials to fade or become brittle.
