we've had an unusually cold and snowy winter and my old boots just weren't cutting it...enter ulu suluk! i have worn them every day since they came, for all my outdoor activities (long walks in the snow with a puppy), and have also worn them to work. they have kept my feet toasty warm and dry! (i was a bit skeptical when i first put them on, but i have been through multiple snowbanks with them, and come out dry every time!) temps here have ranged from 0 to 16 degrees - my feet are usually always cold, but not with these on! plus they are really cute. great customer service with backcountry - they fixed a shipping snafu (ups' fault) - will definitely shop here again!
