These boots have exceeded most of my expectations. They are very comfortable, once sized properly. Note, I had to increase from my normal size 44 to a size 45 because they felt a bit constrained on the top of my foot with my foot bed inserted. Lengthwise they seem about ? size smaller than I expected, but then again my foot beds may have affected this fit too. Take all of this with a grain of salt, as others have told me that theirs fit more true. These boots are simple to lace/adjust on the outside and I have found that the inner boots can be quickly adjusted by adding/skipping eyelets. I haven?t had a lace break yet, but do carry a spare. Given the softer upper materials/design I wouldn?t expect these to last as long as a harder plastic boot might, but they should last several of my seasons. While they are warmer than my older plastics, I still needed over boots and chemical foot warmers on a recent (very cold) Aconcagua summit bid. Around the Pacific NW they have been plenty warm. I have also noticed that they seem to dry faster than my old plastics.

I did a week run in these boots to break them in. I used the boots for my snowshoes, they fit my crampons like they where designed together. The only time my foot where cold in the spantik boot, was the first 15-20 minutes in the morning. Once your feet get warm in these boots they won't be cold again until you take them off. I put my liners in my bag and left my boots out in the vestibule.

I wear these to the summit of Island Peak in Nepal. Super warm and comfortable. Even after 12 hours of climbing 35 to 45% degrees slopes. Crampons fit perfectly.
