I bought these boots since a pair of boots with 600 gram Thinsulate Ultra insulation were not keeping my toes sufficiently warm. I tend to be outdoors for activities such as shopping, snow removal, and other similar activities. There is no comparison in my view - these boots are far warmer. They ought to be since Baffin rates them for -148 degrees F or -100 degrees C.

These boots are outstanding. They slip on and off easily. They are sized well - I wear with a light to medium sock. Even though they are medium-width the inner boot adapts to my narrow foot well. The two-buckle fastening system makes for very easy buckling, unbuckling, and adjustment. Pants legs easily fit inside the boot. The soles have a deep tread that provide very good traction. You can drive in them if you're careful despite their width. You do need to exercise some caution to avoid pressing both the brake and accelerator pedals but it is readily done if cautious.

I only have one regret - that I didn't find them sooner.
