The running distance is just over 300km. They show signs of use, but I think you can still fully experience the potential of these shoes. NIKE Zoom Fly 5 ZOOM FLY5 25.5cm 【Product Description】 ◇ Durable design that can be used from training runs to race day. You can keep wearing them long after you've achieved your goals in your favorite races. With a propulsive, comfortable, and reliable fit, they support high-speed running without fatigue. You don't often see multi-functional shoes in the running field, but there's no reason why there shouldn't be. ◇ Enhanced Responsiveness: The midsole now incorporates ZoomX foam, pursuing a performance level one step above the renowned Zoom Fly 4. The addition of this foam has created a lighter and more responsive cushioning system. Take advantage of the performance of these versatile shoes and run more easily, faster, and more enjoyably. ◇ Stability Where You Need It: The forefoot and heel are slightly wider for increased stability, making it easy to change direction and run long distances. ◇ Maintain Your Rhythm: The carbon fiber plate provides propulsion and smooth transitions at any pace. The plate provides a forward-moving sensation that makes you want to take another step. ◇ Other Features: The upper is made of lightweight mesh material for softness and breathability, creating a perfect fit. The dynamic lacing fit and support that wraps around the midfoot provide a secure fit along the lines. Thank you for viewing.
