Have had these Sorel Caribou boots for years. I've often heard people swear by them. However, as one who works out of doors through winter and frequently stands for long periods on a cold barn floor, they are completely inadequate for keeping my feet warm. I'm not referring merely to temps below zero, or even in the single digits; my feet remain cold even at 34 degrees. I need to use those chemical handwarmers tucked into my socks to keep my toes from going numb.

Despite new liners each year and enough room to wear a silk liner and 2 pairs of Smartwool winter socks, my feet freeze. I do admit that my extremities are often cold from November until April. Ergo, I'm not condemning these boots all around; I'm merely saying that they don't keep *my* feet warm enough, even if I'm moving.

The difficulty seems to be that the sole allows the cold to seep through. With only a felt liner as protection, the insulation just isn't enough.

For temperatures of around 40 degrees, they're fine for me. Heavy and rather cumbersome, but, hey, it's good exercise and I feel light on my feet as soon as I take them off at the end of the day. This year, however, I already bought out all of the handwarmers in the two local stores. So, I'm biting the bullet and looking for new boots!
