Very upset with the quality of the shoe. I used this only for a few runs and the bottom grip started coming off. I stopped running in order to stop the shoe from wearing out fast. Wondering whats the use of this shoe then. It might be so that my copy is defective. But I am stuck with it. I don't have the energy to send it to hoka and deal with the warranty process. I will have to buy a new shoe for interim anyways..
