I have been with Saucony for many years and this was the first time I have been disappointed with one of their products. My last pair of Sauconys were Perregrine 7s which I had for a couple of years. The upper of the 7 looks new but the shoes had to be replaced as the tread was worn. I received a pair of Perregrine 8s and after just a couple of weeks of brief use I noticed that the lining of the right boot had a half inch tear near the laces. Also, the left boot wears out in the same place, and that was before these shoes were used in trail running. Definitely a drop in durability compared to the Perrigrine 7 and previous Saucony running shoes. will return them.
