So far so good, I put just over 20 miles in these shoes in the first three days and the shoes are comfortable, soft and fit my feet. The shoes seem solid but I don't know yet. I was afraid they wouldn't have support with a sock as soft as the upper, but they do. The top is really comfortable. A small minus, the front tongue is high and started rubbing uncomfortably on the front of my ankles, but this is easily resolved by bending the tongue (stays folded for 7 miles) or with higher socks.
