The Muck Boot Company Kids' Rugged II Black Neoprene Waterproof Insulated Boots will protect your child's feet in severe cold with the 5 mm neoprene waterproof bootie insulation backed with a fleece lining. This lining adds extra insulation to keep cold out for kids that want to stay outside playing in the snow all day. Have these kids' snow boots on hand so they can stay protected while on their next adventure, whether at the park on a snowy day or building snow forts in the backyard.
