- Although there is a tear in the fabric on the heel, I always use a shoehorn, so the shape is still intact, and these are beautiful shoes. The following is from the website: A durable design that can be used from weekend training runs to race day. You can continue to wear them for a long time even after achieving your goals in your favorite races. They support tireless, high-speed running with a propulsive, comfortable, and reliable fit. In the running field, you don't often see multi-functional shoes. However, there should be multi-functional shoes. ◇ Enhanced responsiveness: The midsole now incorporates ZoomX foam, pursuing a performance one step above the popular Zoom Fly 4. By adding this foam, a lighter and more responsive cushioning system was born. Let's take advantage of the performance of these versatile shoes and run more easily, faster, and more enjoyably. ◇ Ensures stability where needed: 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 uses a lightweight mesh material to enhance softness and breathability, creating a perfect fit. The dynamic lacing fit and the support that wraps around the midfoot provide a secure fit along the lines.
