Update Nov. 2015 --
I had previously said I wouldnt buy another pair, but I saw another set of these at a local farm supply store and had a bit of a look, expecting to see the rotten garbage rubber on the soles that rotted away on my first pair.

To my surprise I found that Cat had changed out the offending material to a standard type rubber sole.  I was in a bit of a state when I wrote the last review, as the boots had just completely failed after only a few months wear, what I surmised is the soft gray rubber was eaten away by the oil in my work environment. Outside of that, and the waterproof issue, which I assume had alot to do with not having the actual sole of the boot intact, they were comfortable boots.

So , I went with my gut and gave these another shot and they have so far been very solid boots for coming up on a year and a month.  The nice leather finish didn't last super long, but I am hard on my equipment, the fact these haven't imploded after a year is great.  I estimate I still have about 4 months of life in them or better.

A couple notes, the waterproof capacity ended after about 9 months of wear, they are still marginally waterproof, but nothing like when they were new.  Aside from that they are very comfortable, and have withstood abuse well.  Kudos to Cat for fixing the design flaw.  5 star

Bought these end of January 2012.  As of this day the soles have almost completely disintegrated. The boots are no longer waterproof by any means, the padding in the soles has slowly rotted away and the rubber is breaking apart.  I noticed these problems beginning around the first part of July when they lost their water-proof quality.  These boots are better suited for style rather than actual work.  Something I would not have expected from this company.

Bottom line, I've had a few pair of $100+ boots, never have I had a pair fail so completely and swiftly. 2 stars here

Wouldn't even consider buying these for real work again.  They would probably be best suited for casual, comfortable wear.
