These are very nice and comfortable boots. I agree with other reviewers to order half size up for better fit. My foot is 10.5 and the size 11 fits me very good. I have not tried it in snow yet (I live in Los angeles) but the construction of the boot is very good and I am sure it can handle very old temperatures. I will be using it soon in Colorado were I visit my family members. I would highly recommend these boots.
