I ran maybe 20 miles with these. --My shoe mileage tracking (Strava equipment) is the last picture. I used the specifically for one trail race, so they did get a little dirty, but that's what trails shoes are supposed to look like. I prefer Nike Zegama due to foot issues that I have. I love these, so hopefully, someone else can benefit!! Encourages natural running form and reduces impact. Provides superior comfort and shock absorption. Features breathable mesh uppers, enhancing ventilation and keeping feet cool and dry during runs.
