Canada, in 1962, Sorel has long been synonymous with cold-weather footwear—and it was the first company to combine durable leather uppers with waterproof rubber bottoms and warm felt liners (which is totally genius, if you ask us). This boot comes in a color that's exclusive to us and is completely waterproof with a Thinsulate® liner that keeps your feet warm in temperatures as cold as 25 degrees below zero. That's some seriously heavy sledding. Leather upper. Synthetic lining. Rubber sole. Import. Select stores. Item K0723. Very gently worn, 3 times- in excellent condition as you can see in pics.
