From frigid expeditions in the mountains to snowy backyard adventures, trust The North Face Boys' Alpenglow IV Lace Boot to keep your young adventurer's feet warm and comfortable. A waterproof ballistic nylon and leather upper comes seam-sealed for waterproof protection when he's building a snow fort or ripping down the backyard sledding hill, and the flexible TNF Winter Grip rubber outsole helps him break trail through snow and slush without weighing him down. With a Thermalfelt Plus liner, Junior will be able to stay outside in below freezing temps if he wants--and since he takes after you, he'll probably never want to come inside.
