The problem with the uppers seems to happen suddenly. After the first pair went I was vigilant with the next ones checking them after each run. The left one went first, the right one on the next run.
On my feet at least the flex point seems to fall exactly across the back of the toe box where it joins onto the upper. I assume this is causing a stress point in the material which eventually becomes the hole.
First pair bought in Feb and after relatively low mileage due to an injury (200km) before the uppers split just behind the toe cap. I had these replaced by Start Fitness but due to timings I had to buy another pair (from Sweatshop) to have some shoes to run in on holiday.
I'd only done 120km in those ones when the same thing occurred. Sweatshop refunded me rather than replacing them as they said it was a 'recurring issue'.
I'm now in the replacements for the first pair and have ordered a pair of Wave Paradox with the refund credit from Sweatshop.
It's a real shame as I love the Inspires. I've been through a few pairs of 8's, and 9's and had no problems with the uppers at all. I'll see how the Paradox perform although I'm concerned it is a heavier shoe. Hopefully they will sort things out with the Inspire 11's.
^What they both said. I've been through two pairs of Wave Inspire 8's and then three pairs of Inspire 9's and I'm currently on my first pair of 10's and they are the best yet. I have no personal experience of them but I understand the 6's were pretty good too but the 7's weren't so well regarded.
The basic fit an comfort is pretty much the same though and that's no bad thing. If it isn't broke don't try and fix it.
