I've purchased and run in four pairs of these and the first three pairs only lasted about 80 miles before they developed tears and the lugs of the soles came unglued.

The current pair I've been wearing 250 miles as of today which I'm sure is a glitch. One thing I did different is that I never once washed these. They've never touched water except on the trail.

But over the last few runs a tear has developed along the toe edge where it meets the rubber. Once it got about two inches and you could see my finger through the hole I decided to  sew it. But the stitching has come undone on the first run and obviously requires a more extensive stitching job for which I'll have to buy a curved sewing needle.

In conclusion I don't recommend Saucony shoes for trail running.
