Setup, Compatibility & Care
To ensure the best experience with your Nike ReactX Infinity 4 trainers, verify you have the correct UK size, as the fit should be snug but not restrictive around the midfoot. For care, keep the shoes away from direct high-heat sources like radiators to prevent foam degradation. If the trainers become dirty, hand wash them using mild soap and cold water, then air dry away from direct sunlight. To maintain the structural integrity of the cushioning, avoid wearing them for non-running activities that involve heavy lateral dragging or excessive friction on the upper material.
