The North Face Shellista II Mid Insulated Boots are as stylish as they are practical - so much so you'll find yourself inventing excuses to wear them on nice days as well as stormy ones. Waterproof Nubuck with a sealed shell bottom and tall, mid-calf lace up shaft will keep you warm and dry in the nastiest of winter storms. TNF sweetens the pot with the addition of 200 grams of PrimaLoft® Silver insulation and Winter Grip® outsoles with IcePick® lugs for maximum security on icy steps and sidewalks.
