how long do yours last. mine have all suffered catastrophic failure at the toe crease, with the upper material starting to tear at about 200 miles. Doesn't seem to matter if they're nasty miles or just easy, minimally abusive miles.
These ones (v2.5) have 46 hours on them and are in great shape. My first set (v1.5) was retired at 78 hours. Given that I mainly wear them on pretty rugged trail, that probably equates to a bit over 500 and 800 miles respectively (maybe more as they are also my primary trail racing shoes). IIRC, it was a toe crease tear that retired the first pair, but I have no problem forgiving that after that much use on tough trail.
Yeah, was just checking to see what your experience has been. 65 hours on my current pair. Mostly Greenrock and WT. Not sure they'll make it to 78. I don't think the inov8s fair any better.
