Bought these for a trip on the Teton Crest Trail. I wanted a stiff boot that I could kick-step in as the snowfalls this year were high and the trails were under heavy snow. I did take them out for a light 9 mile hike before and didn't get any blisters.
However, as fate would have it, when I took the boots on the hike, they gave me blisters on both heels. I blame that on myself, however, as I know that boots need to be broken in.
The boots are QUALITY, though. They're rigid enough for crampons, sturdy enough to carry heavy loads and the goret-tex is honestly waterproof. The lacing system is ingenious. The bottom-most hooks on the lacing system are V-shaped and cinch the laces down, leaving the option to have the bottom section loose and the top section tighter or vice-versa. Also, they're are two footbed inserts which allow for versatile sizing options.
The soles were good, not great, as far as stickiness and traction.
Cons: The boots did take longer than usual to air/dry out every day and seemed to get more and more moist every morning, almost like they need 9 hrs to fully air out instead of the 8 that I gave them.
All in all, these are great boots that are well-made and I will have them for years.
