I have one of the older pair, that uses the Omintrax V1 soles. The current crop uses Omnitrax V2 soles, and I understand their next batch will be a V3 sole, so there is some planned obsolescence in the boots and soles. I made the mistake of buying some V2 soles (because an Ebay seller wasn't 100% clear in their description), so I have some of those in my fishing junk container. As far as the boots go, they actually held up surprisingly well. I think I have used them for over two years; they are starting to wear out so now I'm stuck with soles that are still mostly good but no source of the original boots. My major complaint was the complete lack of arch support. I used them on a backpacking trip and my arches hurt so badly for a week after the trip. I bought some hiking inserts and replaced the arches/inserts and that solved that problem. I like the big screw-in stud soles for fishing the Erie tribs; they work well on the slimy shale. And I use the rubber cleated soles most of the other places, with the hiking soles periodically. However, I find the hiking soles to be extremely slippery on just about anything.
I will likely try to pick up a pair of boots that uses the V2 soles, so I can use the pairs of soles I bought that didn't fit. Or, if I found a pair of the original model, in size 11, I'd buy them again.
