I can't find any useful information about the level of insulation in their boots. Some say down to -20degrees and another says primaloft. Does anyone have a means of translating to the american standard of thinsulate grams?
There is a three and a half minute tutorial on YouTube about the Crispi Guide GTX boot which did clear up the questions I had about insulation. Ordered a pair and expect to have them in hand next week....
