My friends used to sell these. We all worked in a department store just for shoes. They aren't warm. They should only be used in a ski slope or other areas where there is only snow, no pavement or anything like that.
Why don't you buy the same ones I got? I guarantee that they are warm. I only wore my beige ones once further away then just around the building where I live. I wore them for maybe 2 hours and every time we got back to the car I had to take them off cause they were so warm.
The sole is really good. Wait I'll copy and paste the specifications:
Beautifully feminine boots with a hard-wearing rubber sole. Fashionable fur lining provides superb insulation from the cold. Removable fur insole adds further insulation from beneath the foot. Innovative Receptor® technology supports foot intelligently and adds stability. Stylish nubuck construction in black, brown and sepia. Notice, all fur used in this product is synthetic.
ECCO Receptor® Technology is the outcome of a comprehensive two-year study of the ins and outs of the human bare foot. They define a realm beyond mere comfort - where your shoes enhance your experience by encouraging your feet to move precisely the way nature designed them to.
