The Nike Zoom Fly 6 shoes are designed for immediate use. Simply unbox, lace them up, and go. Ensure you select the correct size for optimal comfort and performance; the fit should be snug but not restrictive, allowing your toes to wiggle slightly. These shoes are compatible with standard road running surfaces. They are not designed for trail running or extreme off-road conditions due to their road-specific traction pattern. To maintain the quality and longevity of your shoes, follow these care instructions: - Hand wash only: Use a mild soap and cold water. Gently scrub any soiled areas with a soft brush or cloth. Avoid harsh detergents or abrasive materials. - Air dry: Allow the shoes to air dry completely at room temperature. Do not use direct heat sources like radiators or tumble dryers, as this can damage the materials and adhesives. - Avoid submerging: Do not soak the entire shoe in water for extended periods. - Store properly: When not in use, store your shoes in a cool, dry place away from direct sunlight.
