Setup, Compatibility & Care
Since the Flex Runner 2 is a slip-on model, no initial setup or lacing is required. Ensure you verify the UK size 1.5 fit before long-term use, as the lack of laces means the fit should be snug but not restrictive. To keep these trainers in peak condition, wipe away loose mud or dust from the rubber outsole after outdoor play using a soft brush. If the fabric upper becomes heavily soiled, spot clean using a mild detergent and a damp cloth; avoid submerging them in a washing machine, as this can degrade the specialized fabric and adhesive components over time. Air dry away from direct heat sources to maintain the shape of the foam and fabric.
