Setup, Compatibility & Care
There is no setup required for the Nike Flex Runner 4; simply slip them on using the dual pull tabs. For a proper fit, ensure the elastic straps are snug against the midfoot without being constricting.
Care Instructions:
- Cleaning: Spot clean the mesh upper using a soft cloth, mild soap, and cold water. Avoid soaking the shoes fully, as this can degrade the foam midsole.
- Drying: Always air dry in a shaded area. Direct sunlight or heat sources like radiators can warp the materials and ruin the adhesive.
- Maintenance: Check the soles periodically for embedded debris or small rocks that might affect traction.
