I know everyone has been on pins and needles waiting for a further report on my shoe wear issue. Your wait is now over and you can all go on to more exciting issues.
I put some effort into analyzing my stride/walking/hiking on various trail types since my initial post and made a startling discovery, at least for me. Though convinced I wasn't rubbing one shoe against the other that did in fact turn out to be the case. It doesn't happen often but occasionally I would feel a slight rub while merrily walking down/and up the trail.
I thought the wear was on top of the shoe collar but it turns out it was on the side and just appeared to be on top. This is due to, for lack of a better description, tension on the collar padding collar that slips towards the shoe interior once worn through. Checking my gators I'm seeing similar wear I hadn't noticed before.
The attached pics are the same shoes shown in my initial post, only about 60 miles later.
Thanks to all who provided input. Another bucket list item crossed off.
