I have always understood that Sorel was the way to go for winter boots. But, I have never owned a pair. When the winter got thick and my Red Wing work boots just weren't cutting it I took the plunge and decided to buy a pair of Sorel Conquest boots.
First off, the only place that even had them in my size (10.5 US) was backcountry.com. Thanks for that!
Within a week I had the boots and went out the next day for several hours of snow shoveling followed by sledding with my 2 year old daughter. I must have been out in the deep snow for a solid 5 or 6 hours and my feet stayed warm and dry!
The boots a very comfortable and as far as I can tell are very well constructed. Both are hallmarks of Sorel boots to my understanding.
I do have a couple of criticisms. First, getting your foot into the boot is difficult. The built in gater is great for keeping snow out and has a similar effect on the wearers foot. Second, the ankle support strap seems truly ancillary to me. The buckle assembly doesn't really allow you to draw the strap tight. I think Sorel should return to the drawing board for the ankle strap.
Overall these are worth the purchase price. As I put them through more winter weather I will do my best to update here with my experience.
Cheers!
