Nike ZoomX Vaporfly Next% 2 - Color: Yellow/Orange - Design: Mesh Upper - Sole: Rubber Sole - Features: Lightweight Design - Lace Color: Black Thank you for viewing. I purchased these from the official store about 3 years ago. The running distance is approximately 200km, including half marathons and full marathons. As you can see in the photos, there is some dirt on the heel of the right shoe. If you are concerned about this, I would recommend refraining from purchasing. The shoes still have plenty of durability, so I think they can still be used for training, such as for full marathons. Please feel free to contact me if you have any questions.
