This is my fourth pair of these boots.  Pros, comfortable out of the box, excellent protection and water proof.  Cons, while previous pairs wore for years, this pair wore out after only 4 months of everyday use.  The soles are coming apart.  Certainly my use has been heavier, but not enough to go from over a year of wear to gone in 4 months.  I will try one more pair and see if this was just a single pair that was bad, but at $154 I expect them to last more than 4 months.  Update October 2015, the next pair lasted 7-8 months before the sole came loose from the shoe body.  Seems like they should last longer than that. So I reduced my rating to 2 stars.
