Sorel was originally a line of winter sport/work boots that were introduced in 1962 by the Kaufman Rubber Company of Kitchener, Ontario. They became its most successful product line. Kaufman Rubber Co. became Kaufman Footwear in 1964. Kaufman Footwear declared bankruptcy in 2000. The Sorel trademark was bought by Columbia Sportswear. Following Columbia's purchase, the Sorel brand was expanded to other products, such as nylon outerwear and other work-related garments.
