Setup, Compatibility & Care
Since the Flex Runner 4 features a slip-on design, no initial setup or tension adjustment is required; simply ensure the correct UK size is selected to ensure a snug fit. To maintain the appearance and functionality of the shoes, avoid machine washing them, as this can degrade the flexible materials. Instead, clean the exterior with a soft cloth and mild soap. If the shoes become wet, allow them to air dry at room temperature away from direct heat sources to prevent the material from warping or stiffening.
