Warm and waterproof, the Sorel 1964 Pac Nylon WP Boot leans on a removable 9mm washable recycled felt liner and a seam sealed nylon upper to keep our feet happy when shoveling the walk or hitting the town after skiing. Other features like a cushioned and supportive midsole as well as a herringbone patterned rubber outsole keep our feet happy and provide tacky traction.
