My Inov-8 315's (subject line is wrong) have died a premature death. I have less than 100 miles on these shoes. The molding nubs are still visible on the treads. I have some 330s that have more than 400 miles and look far better.
I have pretty normal feet, and I use Superfeet Customs for additional control.
But this is downright scary!
I'm in contact with Zappos.com to see what my options are. I'll post again once things are resolved.
Update:
After explaining the situation, I received a full credit, a return shipper, and a "have a great day".
Zappos.com ranks very high in my list of where to shop!
And now I have to decide on another pair of shoes.
