But that’s a thing with all carbon-plated shoes. You get 200-300km out of it. They are usually only worth it, if you run around a sub-3 marathon. It can be worth it for shorter distances but you should have someone looking at your running style because those shoes increase your likeliness of injury if your running style isn’t well or you can keep it up for the whole distance when you are getting tired.
All people I know who use them, just run them once before a race to try them out and after that they are like a very good suit which you only use for special events.
This is really independent of Nike but a thing with those kind of shoes.
