Introduced in the early 1960s, this traditional felt-lined Sorel Pac Boots Waterproof 1964 Pac T has been updated and improved over time. The leather upper has been coated with a thin layer of polyurethane, and all seams have been sealed, making this boot waterproof for the first time. Removable 9mm felt liner doesn't pill like liners of old, and, best of all, it is washable. The pac boot also includes a built-in 2.5mm frost plug designed to keep the cold from penetrating to your feet. The waterproof rubber shell on these Sorel boots features a self-cleaning herringbone outsole. D-ring lace-up system. 10"H. Imported. Men's size 10 only.
