I've had them for a little over 1 month and wear them for 2-4 mile morning walks. Have worn them on several hikes of less than 5 miles each. I struggled to find the right level of comfort for them as they always move around a bit while healing. Wore them on a hike today and they gave me huge blisters. When I got back to the car and took them off, I noticed that the inside of the heel was already frayed and torn. That's what I'm expecting, maybe after a year of constant use, not a month. I just got out of the refund window so $130 was wasted. New Balance does not accept returns on items that were not sold directly to you. I'm staying with Keens from now on. Avoid these shoes.
