Thank you for viewing. This is an item I purchased as a stock. I couldn't smoothly transition to the Zoom Fly 6, so I had two pairs in stock, and this is the remaining one. By the way, I also have three used pairs. [Brand] Nike [Model] Zoom Fly 5 [Model Number] DM8968-001 [Color] Black [Size] Men's 26cm [Accessories] Box For reference: It's a race shoe for full marathons with a sub-4 to sub-5 finish, but it can also be used for point training and long runs for those aiming for sub-3 or faster. My 5km time is around 0:19:00. This shoe is no longer available. The Zoom Fly 6 is more suited for a forefoot strike, while the Zoom Fly 5 is better for heel strikers, which is common among Japanese amateur runners. I'd like someone running around 4:30 per kilometer to wear these. Thanks to the Zoom Fly 5, I made a leap from 5:00 to 3:30 in my first 3 years of running, making it my favorite shoe. As a feature, the 6 has a softer carbon plate and doesn't give a direct sense of rebound. The upper is soft, providing a comfortable fit. It's a lightweight shoe. Breathability is poor, so it's difficult for long distances in the summer. The 5 has a harder carbon plate, requiring some leg strength for the rebound, but you can feel the bounce and spring of a thick-soled shoe. The upper is firm, providing the right amount of pressure for racing. Breathability is better than the 6, so it's good for training over 10km in the summer. This is just my personal opinion.
