NIKE ZoomX Vaporfly NEXT% 2 Size: 25.5cm Men's I have run approximately 500km in them. They have become a bit stiffer, but are still in good condition for training runs. There is no sole separation. I am selling them because I have started using other shoes for training. *The sole on the outside of the left shoe near the toe has a slight scrape, but I don't think it affects running. Please note that returns are not accepted for purchases. Thank you for your understanding.
