The Sorel 1964 Premium Leather Boot's combination of oiled leather uppers and seam-sealed waterproofing creates a rugged, stylish, and timeless look that keeps your feet dry. The insulated removable felted wool and leather liner holds its ground against freezing winter conditions, even down to -25 degrees Fahrenheit. A bonded felt frost plug midsole and waterproof vulcanized rubber shell soles offer durable and cozy cushioning, while the herringbone rubber outsole prevents slipping year after year.
