Great boot! Ive got an average to wide, yet low-volume foot with average instep, very small ankles, and low calves basic boot fitting nightmare for the most part. I do more hiking than my current race boots allow without mind numbing pain, but was very worried that I wouldnt be happy with the performance due to what Ive heard about AT boots in general, but 3 days in- Im really happy. Flex ratings are relative- Id say they compare more to 90-100 flex of most boots Ive tried (depending on temperature), but lateral (side) stiffness is great. Im thinking that most of what Ive heard about AT boots and performance has been from larger guys who like stiff boots and the material technology just isnt yet there for them. However, for women, were lighter, so that doesnt apply.
Have had them paired with my mid-fat (90 underfoot) and wide (115 underfoot) skis and they drive both sets well through moguls, crud, ice- basically anything Ive thrown at them. Admittedly, they dont have the same hard pack performance and vice grip ankle hold that the race boots do, and Im sure I wouldnt want to run gates in them, but they ski much better on the wide variety of terrain I hit, so I would say theyre very comparable to a high end freeride type alpine boot in a lighter weight, more comfortable package. I did need to add a butterfly pad behind my ankles to avoid heel slip, but thats not a big deal to do, and would say that with the intuition liners filling in the extra space, these boots would allow them to fit a narrow foot as well. Also, I initially had a problem with the instep being too tight, but it turns out that the tongue on one of the boots had deformed a bit in the packaging and storing them buckled tight in a warm room for a couple of days solved that problem- I wonder if some of the instep issues that are noted in some of the reviews have to do with this as well and can be rectified.
Get this boot and try it on- if it fits your foot and you find it comfortable, it will do pretty much everything you want it to.
