It's the ultimate cold weather waterproof boot. With a removable 9mm Thermoplus inner boot that's moisture wicking and quick drying and bomber waterproof outer construction that will last through years of wintertime abuse you'll stay comfortable down to -40° F / C should the need arise.
ThermoPlus Felt Inner Boots
Pioneered by Sorel in 1993 after extensive field testing. ThermoPlus InnerBoots provide superb warmth, moisture transfer, comfort, and durability. An advanced four-layer construction wicks perspiration from the foot, maximizes thermal insulation, and reflects body heat back to the foot for a warm, dry foot 'climate'.
Sorel -40° F / -40° C Rated
All Sorel boots that have this rating feature waterproof construction and remain flexible in low temperatures and include a 2.5 mm "frost plug" embedded in the sole for additional under foot insulation.
I bought these boots as a Christmas present for my husband. I got a great deal and quick shipping. My husband hasn't gotten them yet but I know he will love them.
These boots fit the bill! They are as described and the fit is true to size. My shoe size is 12D and ordered these in 13D, perfect! These folks make shopping easy and ship fast too.
