Pros: Light, stiff for weight, great walk mode
Cons: Not good choice for high arches
I really liked these boots in the store and I like them for short runs but despite three trips to the boot fitter I am having a difficult time getting them to be comfortable for more than three hours.
I have very high arches (I can fully slide my index finger under my foot when standing). The prime problem is in how difficult the boots are to get on and off. I've bruised the top of my foot one more than one occasion and a couple times I've had to sit in the truck until the boots warmed up so I could even get them off.
The arch clearance and the toe pressure spots would probably be an easy fix for a boot fitter, if the boots were normal plastic. Unfortunately for me and my freakish feet they boots are some sort of new age plastic and will not hold a punch.
These are probably a great boot for someone with normal volume feet and normal width across the toes but for me they aren't working. It's a shame since I think they are fantastic boots and offer great performance for the price and weight.
Something else to be aware of. The lace system for the liner can jam or fail which leaves you in the position of either cutting the lace to get out of the liner, or having a liner that won't tighten. Don't go for a tour without having a spare lace and tensioner repair kit on you.
Here's another interesting review by a much more experienced skier than myself.
Dane essentially says that he likes the boots but hated the liners and had to replace them to get a good fit.
