I haven't tried these extensively, but took a pair for a spin at the store the other day. They're very good quality, much more so than the Targhee boots that they seem to be replacing. The leather is thicker and the overall build and feel are very good. The new sole is much more comfortable to walk in - it is more flexible and footfalls feel light instead of forced and clompy with the Targhees. They don't offer a lot of underfoot protection so depending on your needs they might be a bit on the soft side. As someone interested in building foot strength, I appreciate the more flexible outsole.

The fit is a lower volume and slightly narrower version of the Targhees. This suits me for the most part, as I have to tighten my targhees up quite a bit to keep them snuggly on my low volume narrow heeled feet. But, the boots are also a little narrower and lower volume in the toes - in the end, after going up a half size my wide toes are still too cramped in them. The tops of my toes are pressed against the tops of the boots, and my pinky toes are especially mashed against the sides and tops.

The lacing is all one slide, no fast loops or lace hooks. It works pretty well overall, but I would probably prefer customisable lacing options. Not a deal breaker.

A great idea overall - as person transitioning to more minimalist footwear, I love the new sole that is lower to the ground, more flexible, and has less heel rise than other Keen boot models. And the lower volume fit is in general good for me. But why did they have to make the toes narrower too? The wide toes is the Keen signature, with no other companies making squared wider toes in hiking boots. A lot of people have low volume feet with wide toes Keen, and for those that don't, a wider toebox doesn't hurt them.
