I have been wearing Salomon backpacking boots for many, many years now.  In fact, I stocked up on a couple of the Discovery GTX boots when I saw they were being discontinued.  I can usually get a couple of seasons out of my boots if I don't get them soaked too often and typically it's the tread that wears out first.  I was in search of a boot to replace the Salomon Discovery boot so I thought I'd give these a shot.  The tread is a different pattern which was not an issue for me but there was a problem for me with the height of the boot itself.  This boot is almost a full inch taller than the older Discovery boots, which made my upper ankle area uncomfortable.  I knew if it was bothering me walking around the house, it was going to be a killer out in the mountains.  I'm a bit puzzled as to the necessity of the extra height because I was able to backpack in my old ones just fine.  I returned these boots and ordered the Quest Prime instead which I think has the same height as my older boots.  There's only one upper hook instead of two which I hope is going to be adequate.  According to the reviews on the Quest Prime, it doesn't seem to be an issue.  I'll be leaving a review on those ones after I try them out.
