Setup, Compatibility & Care
Because the Nike Flex Runner 2 uses a slip-on design, there is no setup required; simply slide the foot into the collar. The shoe fits true to size but is designed to be form-fitting. To maintain the appearance of the Light Smoke Grey and Red colorway, clean the exterior with a soft cloth dipped in a mild detergent solution. Avoid using a washing machine, as the high heat and agitation can degrade the adhesives and foam integrity. To ensure longevity, air dry the shoes in a shaded, well-ventilated area away from direct sunlight or heaters.
