Purchased in July and used for approximately 200km, mainly for jogging. There is some wear on the soles and the uppers show signs of use, but overall, there are no noticeable stains or scratches, and I believe they can still be used. I am selling these shoes because I have purchased new ones. This model can be used for a wide range of activities, from jogging to speed training. How about it?
