It goes until how many celcius under zero???
There is no temperature rating associated with the DC Chalet SE. They would be considered more of a fashion style boot that protects from chilly weather. The materials used are not technical and made to keep things like wind and water from ruining a night out on the town. I would not put much confidence in these if I was using them for some type of expedition. I would be sure that they will keep your toes warm and dry if you were just going to wear them around town, to school, or even something to get you to your car and back while at work.
