"I am the US General Manager for inov-8. First, let me apologize that you've had an issue with what you believe to be the quality of our shoes. I have visited the blog on which you've posted your correspondence with Tom and have seen the image of the shoe. I have also met with my designer on this issue. He is the lone inov-8 designer in the company's history.
He is in agreement with my assessment that it's your pronation that has caused the premature wear on the medial side and the subsequent delamination of the outsole, and not a manufacturing fault. It's possible that it would help to inspect these shoes in person here in my office.
As an aside, be careful how you use the brand name "vibram" when referring to the outsole of a shoe. Vibram is indeed a registered trademark and brand, and is not a generic name for an outsole. Inov-8 does not outsource the production of our outsoles to Vibram like many other footwear brands do, and consider them a competitor, so we'd prefer the brand was not used to describe our outsoles on these blogs."
"I've never had a pronation issue that I'm aware of though I'm not a foot expert, of course. My feet don't turn in or out and my ankles are straight. I have what seem to be quite normal, middle of the road feet. Of course, I'm not walking on level trails so feet have to compensate for that. I DID notice near the end of my last trip that the pictured shoe started to feel like it was sliding which puzzled me and that is when I took it off to discover that whole rear side of the sole had come loose.
I guess I don't have a problem shipping the shoes to you for inspection. Even if I did have some pronation issue, and I'd guess most people have slight issues they aren't aware of, I'd think such an issue would have to be quite severe to cause such a severe effect in such a short time.
Should I ship them to your attention at the address in your sig?"
