I purchased these about a year ago. The running distance is about 5km on a dirt track. They are dirty, but there is almost no wear on the soles. The adhesive on the arch support of the left insole is a little weak from the time of purchase. However, once you put them on, your weight presses down and the insole doesn't shift, so there is no problem with running. Although they are in good condition, they are used items, so please understand this before purchasing. Also, the original box is not included. If you have any questions, please feel free to comment.
