F. McGillwrote a review of Diadora Polaris 2 Shoes on February 25, 2015
Familiarity: I've put it through the wringer
Fit: Runs small
After getting a fatbike last winter, I realized the main weak spot in my cold weather riding gear was my feet. I decided to order these instead of waiting for a much more expensive pair of 45NRTH W�LVHAMMER boots. After using these this winter, I can say these will not cut it for riding in the winters we have had the past couple of years in Michigan. I ordered a size up for me, to make room for an extra layer of socks, and even with the extra layer and chemical foot warmers, these shoes do not keep your feet warm when the temperature is under 30 degrees. And if you have to stand in the snow at all say, while a buddy fixes something on his bike, you may as well head to the car after that. The cold comes right through the bottom of these. Having said all that, they are not a bad waterproof shoe for weather between 35-45 degrees. I wore them on a 40 mile mudfest on a 36 degree day and they kept my feet warm and dry. So they are really more of a late fall, early spring shoe.
