I bought these specifically for my winter trip to Iceland in color Hawk/Gypsy. These are supper cute and stylish for this type of the boot. Unfortunately these were not as warm as I hoped.  I also brought a pair of UGGs with me on the same trip and gotta say in comparison UGGs where much warmer.  However Sorel are waterproof so that made them much more convenient in rain and snow, and compared to UGGs these are much more stylish!
