Craig S.wrote a review of La Sportiva Spantik Mountaineering Boot on January 20, 2017
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
Very happy with all aspects of these boots. Got them for the warmth and have been more than satisfied at 0 degrees with a steady 25mph wind. Feet were actually QUITE warm for someone with cold hands and feet. Thought the one handed lacing system was a little gimmicky until I re-laced them in the cold. Was able to do quite easily with one hand still covered with a liner glove. No issues.
One potential drawback came up. Am using these with Grivel G12 (Cramp-O-Matic style) crampons and the fit over the toe is less than perfect. They (crampons ) don't conform to the shape of the toe too well and needed to be readjusted several times over the first 4 miles of my trip. They just didn't seat correctly in the groove (any suggestions?).
