Helly Hansen calls this boot "the most stylish, comfortable, and warm slip-on on the market." Who are we to disagree? The Helly Hansen women's Seraphina boots sure look the part. With a waterproof leather upper, the boots are perfect for navigating the cold and wet streets and resorts. Adding to that classic leather look is a quilted material that adds a ton of style and warmth to the boots. Slip-ons are super-convenient, so if you already have your gloves or mittens on, feel free to avoid the lacing process altogether. There is a medial zipper to use if necessary, but most wearers simply slip in and go.
