I belabored over the decision of what boots to get for a long time, I made the right choice for sure! I needed a good all around boot to stand up to a variety of winter activities, hiking, biking, snowshoeing, around town use. These are them. Super warm,super comfy. The toe is small enough to fit in the stirups on my bike pedals. The souls are as good as any hiking boot and they fit my snowshoes and micro spikes great. Haven't used them with crampons yet, but besides the not-so-stiffness of the souls, I see no problems (I.e. no ice climbing...).
Spent a whole day walking around and no foot fatigue - which is awesome because all of my other boots have to have gel inserts in order for me to stay on my feet in comfort. They keep my feet warm and are not bulky, they are quite sleek looking actually. Went running around in the snow and no wet feet so far! My short take on these - light as sneakers with extra warmth (and waterproof) due to the magic of gore-tex.
