I believe the running distance is about 50km. I wore these for long-distance runs, so even though the distance is about 50km, I haven't worn them many times. I think the soles are not very worn. These are training shoes, so you can still wear them for a long time. I have experience in track and field, so I take care of them with the correct cleaning method, so please rest assured. ⚠︎Limited color! Instant purchase available
